Description

Maintenance basket and method for servicing a cable car

Technical area

The invention relates to a maintenance basket for cable cars, a cable car and a method for servicing a cable car.

State of the art

Cable cars transport cabins, armchairs or other transport containers hanging on a rope between two places. Preferably, the rope is circumferential. To support and / or guide the rope, the rope, in particular the hoisting rope, carried on supported by support structures roller batteries.

1 and 2 show an example of a section of such a cable car with a cable 3, a support structure 1 and a roller battery. 2

The support structure 1 is here as a pillar with a

Stützeschaft 1 1 and with a yoke also mentioned cross strut 12 executed. But the support shaft 1 1 and / or the cross brace 12 can also be replaced by other support structures, such as a building or a rock. Preferably, the cross member 12 protrudes on two sides, so that at each extremity of the cross member 12 a

Roller battery 2 can be stored on which the rope 3 in

different directions is moved. However, it is also possible that the support structure 1 carries only a roller battery 2. Often wise

Support structures 1 also include a lift-off yoke 13 on which certain parts of the cableway, e.g. the rope 3, can be attached.

The roller battery 2 is an assembly having a plurality of successively arranged rollers 21 for guiding and securing the cable 3. Roller batteries 2 carry the weight of a rope 3 and its hangers (high holder), push a rope 3 down (hold down) or combine these functions (change holder). 1 and 2 show an example of a high holder, which is shown in detail only in Fig. 1,

SCOTEC-1-PCT while Fig. 2, the roller batteries 2 only schematically as a quadrangle

shown. The roller battery 2 usually has a battery structure and pulleys or rollers 21, wherein the rollers 21 in the

Battery structure are rotatably mounted, so that the cable 3 is guided on the rollers 21 of the roller battery 2. The battery structure is usually mounted by means of a main axis 4 rotatable about a horizontal axis which is perpendicular to the cable direction, at one or both ends of the transverse strut 12. However, storage on other parts of a support structure is also possible. Preferably, the

Battery structure itself, a main rocker 24 and a plurality of rockers 25 which rotatably on rocker axes 23 (preferably with the same

Axial direction as the main axis 4) are mounted in the main rocker 24, on. The rockers 25 store the individual rollers 21 (or other lower rockers) on corresponding roller axles 22. Preferably, the lowermost rocker plane has two rollers 21. Preferably, the

Roll battery at least four rollers 21 on.

The roller battery 2 usually weighs more than 500 kg, often more than 1 or 2 tons, allowing for a shift and maintenance of the

Roll battery is impossible by a person on site. The maintenance of such a roller battery 2 includes the removal of all axes of rotation, their cleaning and testing and reinstalling the axes of rotation. For this purpose, the roller battery 2 must be removed with a crane or helicopter from the support pillar 1 to perform this maintenance, and then be mounted on this again. This further requires that the roller battery 2 is accessible from above, for which, as a rule, the cable 3 has to be removed from the rollers 21 of the roller battery 2 and moved inwards. This requires in addition to the high cost of transporting the roller battery several hours of preparation for each pillar. The current solution of the prior art for the maintenance of the roller batteries is therefore complicated and unsatisfactory. Also, due to the high weight of the roller batteries and the high load thereon, there is no solution in the prior art, as the axes of the roller battery can be maintained without removing the roller batteries.

SCOTEC-1-PCT Presentation of the invention

It is an object of the invention to improve the maintenance of cable cars, in particular of roller-type batteries.

According to the invention, this object is achieved with a method for maintenance and a maintenance basket according to the independent claims.

By using a maintenance basket, a maintenance technician can move directly to the cable car maintenance center and do the necessary on-site maintenance. The costly disassembly and removal of maintenance parts such. of the

Roller batteries are thus eliminated.

Further advantageous embodiments are specified in the dependent claims.

In one embodiment, the cable car has a roller battery at the service station, and the maintenance work includes the step of securing the load of the roller battery to a support structure of the roller battery. Thereby, the load of the roller battery, e.g. caused by their weight or by the rope of the cable car, are taken from the axis so that it can be moved, cleaned and / or checked without having to carry away the roller battery. Thereby, the load of the roller battery can be removed from the axle, so that it can be cleaned and / or checked while the roller battery 2 or the main rocker 24 remains in the secured position. Preferably, the load is secured to a support yoke of the support structure. To secure the load is preferably a

Lift mechanism used.

In one embodiment, the maintenance basket has a lifting mechanism with which the height of the working platform can be adjusted relative to the rest of the maintenance basket. This allows the maintenance technician located on the work platform to

SCOTEC-1-PCT Maintenance of the cable car to adjust the height of the work platform so that it reaches the appropriate maintenance point.

In one embodiment, the lifting mechanism has two lifting mechanisms. This allows the height of two sides of the

Working platform can be set differently.

In one embodiment, the maintenance basket has two hangers for hanging the maintenance basket in place at two attachment points of the rope. This has the advantage that the work platform can be large enough for the necessary maintenance work and still hangs stable on the rope. This embodiment is particularly advantageous in combination with the two lifting mechanisms, as this allows the height difference of the rope at the two attachment points with the two lifting mechanisms can be compensated.

Other embodiments will become apparent from the description of an exemplary embodiment.

Ways to carry out the invention

The elements of a cable car have already been described in the context of the prior art in FIGS. 1 and 2 and will not be described again here.

For maintenance of the cable car now a maintenance basket is proposed, which can transport a maintenance technician to a maintenance point of the cable car. Figs. 3, 4, 5 and 6 show a

Embodiment of such a maintenance basket 5. The maintenance basket 5 has a maintenance basket structure, a hanging device 6 and a working platform 8.

Hanging device 6 at least one hinge 63, 64 which rotatably supports the maintenance basket structure with one, two or more degrees of freedom. Preferably, the at least one hinge 63, 64 allows a rotatable mounting of the maintenance basket structure or the maintenance basket 5 about a horizontal axis 63 ', which is aligned perpendicular to the cable direction. Preferably, the at least one joint 63, 64 allows a rotatable mounting of the maintenance basket 5 or

Maintenance basket structure about a vertical axis 64 '. This is particularly advantageous, in the embodiment described below with two hangers 6. In the embodiment, the two joints 63 and 64 are provided for the two rotations. But it is also possible to provide only one common joint for both rotations. It is also possible to provide no rotatable mounting in the hanger 6. Preferably, the hanger 6 has two of the hanger devices 6 described above, so that the maintenance basket 5 can be stored at two attachment points along the rope 3.

Preferably, both hangers 6 are attached to the same cable 3. However, it is also possible to use the two hangers 6 on different ropes, e.g. to fasten or guide a pull rope and a carrying rope. The two attachment points of the maintenance basket 5 along the rope 3 are preferably located on the two extremities of the maintenance basket 5. The attachment of the maintenance basket 5 to two

Mounting points allows a stable (not fluctuating)

Work platform 8, which is a great help for maintenance. By the hinge 64 with the vertical axis of rotation 64 'may be such

Maintenance basket 5 or the maintenance basket structure better around the

Circulation points at the ends of the cable car or other curves are performed. However, it is also possible to attach the maintenance basket 5 or the maintenance basket structure to only one hanging device 6.

Preferably, the working platform 8 has a testing bench for magnetic-inductive material testing of parts of the cable car, in particular of the roller battery, in particular of axles, in particular of the main axle 4, the rocker axles 23 and / or the roller axles 22. This test bench

SCOTEC-1-PCT for magnetic-inductive material testing is also referred to as MT Prüfbank. The magnetic-inductive material test is preferably a magnetic particle test. The test bench is mobile on the

Working platform 8 attached so that the test bench for material testing of the main axis 4 of the roller battery to the recess 4 'in the support structure 1 can be moved. For the material testing of the remaining parts, the test bench is preferably mounted on the work platform 8, preferably on the work table. The material test is preferably one

non-destructive material testing (ZfP). This is useful, for example, for detecting cracks in the part.

Preferably, the working platform 8, preferably the work table has a small parts cleaner for cleaning the parts of the cable car to be serviced. Preferably, the small parts cleaner is designed to clean the said parts by means of a cleaning fluid. The

Cleaning fluid is for example compressed air or a cleaning fluid. As a cleaning liquid, a grease-dissolving liquid is preferably used to rid the parts of soiled oil or grease.

Preferably, the small parts cleaner has a cleaning tool, which is in fluid communication with a source or storage for the cleaning fluid, so that the said parts can be cleaned with the cleaning tool and the cleaning fluid leaving the cleaning tool. Preferably, the small parts cleaner further comprises a catching device to catch a drainage liquid. The small parts cleaner and / or the cleaning tool is so mobile that it can be guided to the recess 4 'of the main axis 4 in order to clean the main axis 4 on site.

Preferably, the working platform 8 has a plurality of transport boxes. The transport boxes are preferably on

attachable to different positions on the work platform 8.

Preferably, the transport crates on the railing 82 of the

Work platform 8 attached. Preferably, the transport boxes on the outside of the working platform 8 on the railing 82 of

Fixed work platform 8, so that the transport boxes does not restrict the working space of the working platform 8 within the railing 82. The

SCOTEC-1-PCT Transport crates are preferably completely closed (with the possible exception of a small opening on the lower side for condensed water), so that the cargo is protected against wind and weather. The

Transport crates are preferably attached to the side of the work platform 8 on the railing 82, which points away from the supports 1

(usually right in forward direction).

Spare parts such as spare rollers 21, spare rockers 24, 25 and spare axles 4, 22 and 23 are also transported in the maintenance basket 5 to replace these parts, if the test a

Damage to these parts tested results. The working platform 8 has on the side facing the supports 1 side of the working platform 8,

preferably on the local railing 82 brackets for the spare parts. These brackets are preferably designed so that the

Spare parts can be kept safe even when moving the work platform 8. Preferably, these brackets are arranged on the inside of the railing 82, so that the weight of the spare parts serves as a balance weight for the maintenance basket 5.

The work platform 8 preferably still has

Maintenance tools, in particular test and / or inspection tools and / or consumables such as lubricants, plain bearings, screws, nuts, etc. on. These can be transported, for example, in the transport crates and / or on the work table.

The work platform 8 also has at least one securing device, 9 such as cables, load slings and / or

Hydraulic cylinder on. This securing device (s) allow the working platform 8, the maintenance basket 5, the cable 3, the roller battery 2 and / or the rocker (s) 24, 25 on the support 1, in particular on the

To secure Abhebejoch 13. As a securing device 9, a hydraulic cylinder is particularly advantageously used. A hydraulic unit is used to confirm the hydraulic cylinder. Advantageously, a hydraulic unit is used for the actuation of a plurality of hydraulic cylinders. The hydraulic unit is preferably mechanically, i.

SCOTEC-1-PCT driven by a maintenance technician. However, an electric drive is possible.

The work platform 8 preferably has a hydraulic pump, the hydraulic fluid from a hydraulic accumulator in a

Hydraulic system pumps. The hydraulic pump can be driven manually or by an electric motor. The hydraulic system has a distributor block which holds the hydraulic pump with several

Hydraulic consumers connects. The connection to the consumers can be fixed or, as preferred, be implemented removably via connections. For example, a consumer could be a hydraulic motor to operate the lifting mechanism 7 or the other lifting mechanism. Further consumers could be hydraulic cylinders, which can be used as securing devices 9 as described above.

The work platform 8 preferably has a power generator which generates the power necessary for the tools and / or the test bench. The power generator could possibly also directly drive the hydraulic pump.

Preferably, the work platform 8, preferably the work table, on a further lifting mechanism. This further

Lifting mechanism is for example a scissor lift. The lifting mechanism is arranged on the work platform 8 or the work table so that it is located below the rope 3. The lifting mechanism can also be a crane. Preferably, the crane has a first support device, a second support device and a crane cross member. The first support device is mounted or attachable to the work platform 8. The second support device can be fastened or set down on the support structure 1, preferably on a flat platform (pedestal) of the support structure 1. The crane crossmember is arranged between the two support devices. The first and / or the second support device is adjustable in height, so that the crane cross member can be aligned horizontally. The first support device can firmly on the

Work platform 8 or on a movable in the cable direction of the structure

SCOTEC-1-PCT Work platform 8 mounted so that the first support device only in height and position in the cable direction must be adjusted and does not need to be mounted with each maintenance. Preferably, the first supporting device or its movable structure is mounted on the outside of the railing 82 of the working platform 8 or on the railing 82. As a result, the space on the work platform 5 is not restricted by the crane. The first support device thus remains mounted during the travel of the maintenance basket 5. However, the first could be

Supporting device can also be easily supported within the railing 82 and / or on the floor of the working platform 8. The second

Support device is preferably supported on the support structure 1. The first and / or second support device has two support legs, so that this support device is more stable. The cross member and / or the second support device of the crane can be retracted or folded or disassembled while driving the maintenance basket 5. Thus, for example, the cross member can be moved to the side facing away from the supports 1 side of the maintenance basket 5, so that the cross member, possibly does not interfere with the second support device while driving. On the

Cross member is preferably arranged a cable with which parts can be lifted. The position of the cable on the cross member between the first and second support device can preferably be moved (even under load) and fixed. This is preferably by a displaceable on the crane crossmember

Carriage or trolley reaches where the cable is attached. The crane is preferably made of metal, preferably of aluminum. With the further lifting mechanism, the roller battery 2 or parts of the roller battery can be relieved to disassemble the roller battery 2 for testing and / or maintenance. In particular, the other can

Lifting mechanism for supporting the rockers 25 and / or rollers 21 are used to expand the rocker and / or roller axles 22 and / 23 for testing and / or maintenance.

In one embodiment, the work platform 8 is movable relative to the maintenance basket structure. This allows the

Working platform 8 compared to the maintenance point better (than the predetermined by the maintenance grain structure position of the work platform 8)

SCOTEC-1-PCT position. In a simple case, the work platform 8 can be fastened to the support structure 1 during the maintenance work. This can be achieved, for example, with load slings, cables and / or hydraulic cylinders which are movable in their length. In one

preferred embodiment, the maintenance basket structure on a lifting mechanism 7, the working platform 8 against the

Can lift maintenance basket structure. Thus, the work platform 8 can be brought closer to the maintenance point. Preferably, a hydraulic mechanism is used as the lifting mechanism 7. However, mechanical lifting mechanisms are also possible. Preferably, the lifting mechanism 7 is actuated by the force of the service technician.

However, a motorized operation is possible. Preferably, the lifting mechanism has two lifting mechanisms so that the ends of the working platform 8 can be raised in the direction of the cable differently from the maintenance basket structure (and preferably independently of each other). Thereby, a rope pitch can be compensated when the maintenance basket structure is suspended at two attachment points along the rope 3. This is shown by way of example in FIG.

In a preferred embodiment with two

Hanging devices 6 and two lifting mechanisms 7 is the

Maintenance basket structure formed of two separate maintenance cortical structures, which are each attached to one of the two hangers 6. Each maintenance basket structure has one of the lifting mechanisms 7. The two lifting mechanisms 7 each have a lifting carriage 71, which is connected to a corresponding attachment point of the working platform 8 (preferably at its extremities in the cable direction).

Between one or both lifting mechanisms 7, preferably between the lifting carriage or carriages 71, and the working platform 8, a joint 81 is preferably arranged which allows rotation of the working platform 8 relative to the lifting carriage 71 about a horizontal axis 81 '. Preferably, each of the two maintenance basket structures forms one

Guide for the lifting carriage 71 off. Preferably, the two

Maintenance Korbstrukturen connected only via the work platform 8. This saves a lot of weight. However, it is also possible to have a common / connected maintenance basket structure between both hangers 6

SCOTEC-1-PCT provide on which then the working platform 8 (movable or not) is stored.

Fig. 8 shows a further embodiment of a

Maintenance basket.

The work platform 8 has a frame. The frame forms a railing 82 and a floor frame. The frame and / or base frame is made of (welded)

Metal bars formed. The floor frame carries a floor surface on which the service technician (s) can stand and move, and / or the worktable. The bottom frame preferably forms a platform surrounding the work platform 8 / circumferential. Preferably, the floor frame further between the

Frame linkage on another reinforcement or stiffening linkage.

The maintenance basket 5 in Fig. 8 has the same as the last one

Embodiment two hangers 6, preferably on the two extremities (in the cable direction) of the maintenance basket 5 on. These are described in more detail here. The hanger 6 has a

Suspension linkage 61, which is attachable to the cable 3 with a cable attachment mechanism such as a clamp, coupling or coupling clamp. The hanger rod 61 has a roughly U-shaped shape so that the hanger rod 61 is first led away from the cable 3 roughly horizontally (perpendicular to the cable direction), then roughly down vertically, and then again roughly horizontally (perpendicular to the cable direction ) is again guided under the cable 3 or under the cable attachment mechanism. Preferably, the hanger 6 further comprises a cross member 65. The cross strut 65 is attached below the hanger rod 61. The cross member 65 is preferably formed, the

Work platform 8, preferably the lifting mechanism 7, the

Working platform 8 height adjustable carries, to carry. The cross member 65 is preferably slidably attached to the hanger rod 61. The

Displacement direction is preferably horizontal and / or perpendicular to the cable direction. This allows the work platform 8 in the direction of displacement

SCOTEC-1-PCT optimally positioned to the support structure 1, in particular to the roller battery 2. The cable direction of the maintenance basket is also without

Attachment to a cable 3 of a cable car through the

Cable attachment mechanism through which through the two

Hangers 6 defined direction or through the

Fastening mechanism 62 defined. The displacement device for moving the work platform horizontally and / or perpendicular to the cable direction but could also be realized differently. The described hanging device 6 could also be used as a single hanging device 6 for a maintenance basket. The described

Hanging device 6 can also in the above-described

Embodiment of the maintenance basket 5 of Fig. 3 to 6 are used. The cable attachment mechanism preferably has one

Clamp on, with the hanger 6 can be mounted on the rope 3. For the circulation of the maintenance basket 5 from the first direction of travel to the opposite second direction of travel, for example at the mountain station, the hanger 6 can thus be uncoupled from the cable 3. Preferably, the

Rope attachment mechanism continues rolling on to the

Hang device 6 to lead in a designated circulation guide while disengaged during the circulation clamp. Preferably, the rolling means have two in the cable direction

arranged in a row on rollers.

The embodiment in Fig. 8 shows a further alternative for a lifting mechanism 7. The below-described

Lifting mechanism 7 is preferably at both extremities in

Rope direction of the work platform 8 is arranged so that the distance of the working platform 8 from the rope 3 and the hanger 6 at both ends of the working platform 8 can be adjusted. The lifting mechanism 7 described below can also be used in the embodiment of the maintenance basket 5 shown in FIGS. 3 to 6 described above.

The lifting mechanism 7 has a rope-like structure 75, the working platform 8 with the maintenance basket structure or with the

SCOTEC-1-PCT Hanging device 6 connects. The rope-like structure 75 is preferably a chain, but may also be formed as a rope, wire rope or other flexible, longitudinally supporting, elongate structure. The chain is preferably a one-dimensionally movable chain, preferably a roller chain. One-dimensionally movable chains have the advantage that the movement of the working platform 8 except in the plane of

Chain movement is not possible or only steamed. This prevents excessive fluctuation of the working platform 8 under the rope 3.

Preferably, the direction of movement of the one-dimensional chain is arranged parallel to the cable direction. However, it is also possible to use two-dimensionally movable chain, such as a link chain, or other one-dimensionally movable chain types.

Chains have a high load capacity and are very stable

External influences such as fire and weather. The rope-like structure 75 preferably has two rope-like substructures 75, which connect the working platform 8 with the suspension device 6 (in particular with the cross member 65) on two sides of the rope 3 or the rope attachment mechanism. Preferably, two corners of the work platform 8 are connected to two lateral extremities of the hanger 6 and the cross member 61, respectively. In the case of two lifting devices 7 thus the four corners of the working platform 8 with four rope-like sub-structures 75 are connected to the two hangers 6. In that shown in Fig. 8

Embodiment, the two rope-like sub-structures 75 are formed from a common rope-like structure 75. The common rope-like structure 75 extends from (a first end) of the crossbar 65 to (a corner) of the working platform 8. There, the rope-like structure 75 is deflected and again led back to (center of) the crossbar 65. There, the rope-like structure 75 is deflected again and led back to (another corner) of the working platform 8. There, the rope-like structure 75 is deflected again and led back to (the second end) of the crossbar 65.

The lifting mechanism 7 also has a mechanism that can change the length of the rope-like structure 75 between the hanger 6 and the working platform 8. The mechanism is preferably designed to engage in the rope-like structure and the

SCOTEC-1-PCT to move rope-like structures relative to the mechanism. This mechanism can be arranged either in the hanger 6 or on the work platform 8. In the exemplary embodiment in FIG. 8, this mechanism is arranged in the hanger 6, here the transverse bar 65, which shortens or lengthens the end (s) of the rope-like structure 75. The mechanism can, for example, as a rope or

Chain hoist are formed.

A disadvantage of the mechanism described is that the adjustability of the height is limited by the maximum length of the loop formed by the rope-like structure 75. Due to the zigzag guiding of the rope-like structure 75, a very long chain must be used in order to achieve great adjustability. This leads to a great weight.

9 to 12 show two alternative embodiments for the lifting mechanism 7. The two rope-like substructures 75 connect the hanger 6 and the work platform 8 as described above. A first end of the rope-like sub-frame 75 is (fixed) to one of the work platform 8 or the hanger 6 connected. The first end opposite the first end of the rope-like sub-frame 75 is connected to the mechanism on the other of the working platform 8 or the hanger 6. The mechanism can do that

Free to set breakpoint along the rope-like structure 75 and / or changed the distance between the hanger 6 or the

Work platform 8. This allows the distance between hanger 6 and the work platform 8 to adjust to the length of the rope-like sub-structure 75. As a result, the work platform 8, for example, without crane or other lifting device to a nearly arbitrarily high rope 3 to the attached to the rope 3 hangers 6 are pulled up. Only the hangers 6 need to be attached to the cable 3. Preferably, the mechanism is disposed on the work platform 8. This allows the remainder of the rope-like sub-structure 75 to be suspended or stored below the mechanism or work platform. The second end of the rope-like sub-structure 75 can for

Example in a box below the mechanism and / or below the

SCOTEC-1-PCT Work platform to be transported. Due to the open second end of the rope-like sub-structure 75, the two can

Hanging devices 6 are attached without the working platform 8 to the cable 3 and the working platform 8 are subsequently connected to the two mechanisms of the lifting mechanism 7 at the second ends of the four rope-like substructures 75.

In the embodiment in FIGS. 9 and 10, the mechanism for each rope-like substructure 75 has two support wheels 77. Each retaining wheel 77 engages the rope-like substructure 75 and holds the rope-like substructure 75 firmly. The rope-like substructure 75 extends between the two retaining wheels 77, so that the rope-like substructure 75 can not slip out of the two retaining wheels 77. By rotating one or both of the two support wheels 77, the position of the

rope-like structure 75 are moved to the mechanism or to the working platform 8. The support wheels 77 are preferably arranged so that the space between the two support wheels 77, through which the rope-like substructure 75 runs, is arranged (in the vertical direction) below the attachment of the first end of the rope-like substructure 75 to the suspension device 65. As a result, the rope-like structure 75 extends from the first end to the mechanism or the

Space between the two support wheels 77 and also after the mechanism straight in the vertical direction. The clamping means 78 and the bearing means 78 secure the axes of rotation of the two axes of rotation 76 on which the support wheels 77 rotate to prevent jumping out of the rope-like structure 75 from the support wheels 77. The axes of rotation 76 are arranged parallel to each other. The axes of rotation 76 are arranged parallel to the narrow side of the working platform 8 and / or at right angles to the long side of the working platform 8 or to the cable direction. The axes of rotation 76 are rotatably mounted on the work platform 8. The support wheels 77 are preferably sprockets, e.g. a gear for a roller chain or a pocket wheel for a link chain. For other rope-like structures 75, for example, clamping or friction wheels may be used as the retaining wheels 77. Preferably, the four support wheels 77 for the two rope-like sub-structures 75 run on the same two axes 76, so that the two support wheels 77 are simultaneously rotated on both sides

SCOTEC-1-PCT and the distance between the hanger 6 and the work platform 8 for both rope-like sub-structure 75 is equal. The mechanism further includes a rotating means 79 which causes rotation of the axle 76 and the axles 76, respectively. The rotating means 79 may have a translation which reduces the effort required to rotate the axle 76. The rotating means 76 is preferably hydraulic.

In the described embodiment, the two axes 76 of the support wheels 77 are arranged at the same height. Alternatively, it is also possible to arrange the axes of rotation 76 of the two support wheels 77 vertically (and horizontally) offset from one another, so that the axes of rotation 76 are arranged at different heights. This is shown, for example, in the embodiment in FIGS. 11 and 12. This allows the rope-like substructure 75 to lead from the first end of the rope-like sub-structure 75 to the lower support wheel 77, around this lower support wheel 77, back to the upper support wheel 77, to guide the upper support wheel 77 back down. The deflection around each retaining wheel 77 is preferably 180 °. A safety device 90 on the side of the upper support wheel 77 facing the second end of the cable-like substructure 75 can be used to prevent the cable-like substructure 75 from jumping out of the upper support wheel 77

prevent. A similar safety device 90 could be used on the other side of the upper support wheel 77 and / or on one or both sides of the lower support wheel 77.

In an embodiment not shown, it would also be possible to arrange the two axes of rotation 76 vertically one above the other, so that the rope-like substructure 75 once on a first horizontal side about the upper support wheel 77 and once on one of the first

horizontal side opposite horizontal side to the lower holder wheel 77 runs. Thus, the rope-like sub-structure 75 is guided in an S-shape between the two holding wheels 77. The weight of

Work platform 8 causes the rope-like substructure 75 are pressed against the support wheels 77.

SCOTEC-1-PCT In an embodiment not shown, it would also be possible to arrange the mechanism for adjusting the distance between the hanger 6 and the work platform 8 on the hanger 6. The first end of the rope-like substructure 75 is then placed on the work platform 8. The mechanism could thus consist of (only) two (instead of four) retaining wheels, wherein a respective rope-like sub-structure 75 is deflected by 180 ° about each retaining wheel. The second end of the rope-like sub-structure 75 can hang freely after the deflection around the corresponding retaining wheel. The rope-like substructured 75 is guided by the working platform 8 to the corresponding retaining wheel of the suspension device 6, where it is deflected by 180 ° and then guided downwards again (freely suspended). The two retaining wheels for the two rope-like substructures 75 may be mounted on a common axis 76. The common axis 76 may be mounted in the cross member 65 or at least parallel thereto.

Preferably, the hangers 6 have a hinge, not shown, which allows rotation about a vertical axis. For example, the hinge could be located between the hanger linkage 61 and the cross member 65 or in the hanger linkage 61.

According to the invention, the maintenance work on cable cars can be significantly shortened and simplified if the maintenance engineer is transported to the maintenance center with a maintenance basket suspended from the cable 3 of the cable car and the necessary on site

Maintenance works.

In Figs. 7A to 7E, the steps of a method of servicing a cable car are illustrated by the example of maintenance of a roller battery 2, e.g. described in the introduction.

In a first step, a maintenance basket, e.g. the maintenance basket 5, attached to the cable 3 of the cable car. Then the service technician with the maintenance basket 5 is sent to the service station, e.g. the location of the waiting roll battery 2, transported (see Fig. 7A).

When the maintenance basket 5 has a movable work platform 8,

SCOTEC-1-PCT can the work platform 8 still be positioned so that the

Maintenance work on the roller battery 2 can be performed well (see Fig. 6). This is preferably done with the actuation of the

Lifting mechanism 7 and the lifting mechanisms 7 realized. Of the

Maintenance basket 5 or the working platform 5 is preferably stabilized on the support structure 1. This is achieved for example by supporting rods.

In a second step, the maintenance work is now carried out. In the case of the roller battery 2, the first problem is that the main shaft 4, on which the entire weight of the roller battery 2 and the load of the cable 3 rests, must be removed. For this purpose, in a preferred embodiment, the roller battery 2 at the

Maintenance point to the support structure 1, preferably secured to the Abhebejoch 13. As a result, the load on the main axle 4 is reduced so much that the main axle 4 can be removed at the service station. For this purpose, a securing device 9 is used.

Preferably, the backup of the roller battery 2 is based on a

Suspending the load of the roller battery 2 on the support structure 1 and the Abhebejoch 13 (see Fig. 7B). This can be done, for example, with one or more lifting mechanisms 9, e.g. a cable, done. Cable also includes rope-like structures, such as bands, chains, etc ..

Preferably, the cable has a rope-like structure 91 and a

hydraulic cylinder 92 on. Preferably, the hydraulic cylinder 92 is a double-acting, dual hydraulic cylinder. However, in some cases, the fuse can also be based on the support on the support structure 1 or lift-off yoke 13, e.g. when the rope 3 the

Rolled battery 2 applied to the top and the roller battery 2 must be supported by the Abhebejoch 13 so that the main axis 4 can be removed from the roller battery 2 from the roller battery 2. After securing the roller battery 2, the main axis 4 is now removed from the main axis opening 4 'in the roller battery 2 and the support structure 1, while the roller battery 2 or at least the

Main rocker 24 is held in place by the securing device 9 (see Fig. 7C). Now the main axis 4 can be cleaned and / or tested. Preferably further (e.g.

SCOTEC-1-PCT Rocker and roller) axles 22 and 23 removed from the roller battery 2, cleaned and / or tested. As described above, the further lifting mechanism of the working platform 8 can be used to support the rocker 25 or the roller 21 for the removal of its axle 23 or 22. All removed axles 4, 22 and / or 23 are returned to the

Roller battery 2 installed (see Fig. 7D). Since the roller battery 2 is free of load or at least reduced load by the securing device 9, the maintenance technician can position the roller battery 2 to the support structure 1 so that the main axis 4 can be reintroduced into the Hauptachsöffnung 4 'of the roller battery 2 and the support structure 1.

Thereafter, the roller battery 2 is released, so that the load again on the main axis 4 superimposed (see Fig. 7E).

In a third step, the maintenance technician may transfer the maintenance basket 5 to a next service point, e.g. the next

Roll battery 2 are transported.

In an alternative second step, one or two of the following two maintenance steps are performed: a cleaning and / or revision / inspection of the main axis 4 and a cleaning and / or

Revision / check of the remaining roller battery 2. If both

Maintenance steps are executed, so their order does not matter.

Before carrying out one or both of the maintenance steps, the cable 3 is preferably secured to the support structure 1, preferably to the lift-off yoke, by means of a securing device, preferably a hydraulic cylinder. The securing of the cable 3 preferably includes lifting the cable 3 off the rollers of the roller battery 2. However, this step is optional and the maintenance steps could also be performed with the cable 3 mounted on the rollers 21 of the roller battery 2.

Preferably, the rope with a securing device on the main axis 4 and / or in the middle of the main rocker 24 on the

Support structure 1 secured. Preferably, the cable 3 is raised only so far that the cable 3 is guided on the first and second sides of at least one of the rollers 21 mounted in the main rocker 24. This

SCOTEC-1-PCT provides additional security for the guidance of the rope 3 and prevents cumbersome threading of the rope 3 in the rollers 21 after the

performed maintenance work.

In the following, the cleaning and / or inspection of the main axis 4 will be described. As previously described in one

Preferred embodiment, the roller battery 2 at the

Maintenance point to the support structure 1, preferably secured to the Abhebejoch 13. As a result, the load on the main axle 4 is reduced so much that the main axle 4 can be moved or removed at the service point. This is a safety device

used. Preferably, the safety of the roller battery 2 is based on suspending the load of the roller battery 2 on the support structure 1 or the lift-off yoke 13. Preferably, the safety device has two sub-safety devices, preferably two hydraulic cylinders, which connect the two extremities in the cable direction of the main rocker 24 to the support structure 1 or the Abhebejoch 13 secure or hang.

However, the roller battery 2 or the main rocker 24 could also be secured to the support structure 1 with the securing device 9 described above. Preferably, the main axis 4 is not completely taken out of the recess 4 'for testing or cleaning. The major axis 4 is supported on a first side (e.g., facing away from the support structure 1) and a second side of the main rocker 24 (e.g., facing the support structure 1) in the recess 4 'of the support structure 1 (see Fig. 13A). The main axis 4 is now pushed out in a first direction (perpendicular to the cable direction and / or away from the support structure 1) from the first side of the recess 4 '. The main axis 4 is (only) pushed out so far, so that the main axis 4 is still on the first side in the recess 4 'of the support structure 1 and the main rocker 24. At the same time, from the second side, an auxiliary axis 96 with the same diameter or a (somewhat) larger diameter as the main axis 4 is pushed into the recess 4 'of the support structure 1 and the main rocker 24 (see FIG. 13D). The auxiliary axis is pushed in so far, so that the auxiliary axis is located on the second side in the recess 4 'of both the support structure 1 and the main rocker 24. Thus, the main shaft 4 secures the main rocker 24 on the first one

SCOTEC-1-PCT Side and the auxiliary axis, the main rocker 24 on the second side. This also avoids a complicated alignment of the recess 4 'of the main rocker 24 to the recess 4' of the support structure 1, to the

Main axle 4 later re-introduce. Figs. 13B to 13D show a preferred method of partially pushing out the major axis 4 from the recess 4 'as described. The auxiliary axle 96 is arranged on the second side of the auxiliary axis 96 on the main axis 4, so that their ends lie on each other and their circumference flush

are arranged. With a hydraulic cylinder 94, the auxiliary axis 96 is pressed against the main axis 4, so that the main axis 5 is pushed out on the first side and at the same time the auxiliary axis is pushed on the second side in the recess 4 'of the support structure 1. As described, the auxiliary axis 96 far into the recess 4 '

pushed until the auxiliary axis 4 'is located both in the recess 4' of the support structure 1 and the recess 4 'of the main rocker 24 and the main rocker 24 carries on the second side (see Fig. 13C).

Preferably, the auxiliary axis has one along the axial direction

through recess on. Preferably, this recess is arranged rotationally symmetrical, so that the auxiliary axis 96

is formed hollow cylindrical. The hydraulic cylinder 94 has a punch 93, which can be moved by the hydraulic of the hydraulic cylinder 94 and the auxiliary shaft 96 can slide into the recess 4 '. Either the punch 93 has an attachment 95 which broadens the punch 93 so far that the punch 93 can not be inserted into the recess of the auxiliary shaft 96. Alternatively, the punch 93 may be slid so as to press against the auxiliary shaft 96. Alternatively, the punch 93 may be formed so wide that it does not in the

Recess 4 'fits. In the latter case, for the next step, the punch 93 must have an attachment which fits into the recess 4 '. The punch 93 is now pushed through the continuous recess of the auxiliary axis 96 and now pushes the main axis 4 further out of the first side of the recess 4 'out (see Fig. 13D). The main axis 4 is pushed out only so far that the main axis 4 is still in the

Recess 4 'of the main rocker and in the recess 4' of the first side of the support structure 1 is mounted. Thus, for most of the time, the main rocker 24 remains on both sides by the auxiliary axle 96 and partially

SCOTEC-1-PCT pushed out main axle 4 secured. This method has the advantage that the auxiliary axis 96 can be made relatively short and thus weight-saving. In addition, the auxiliary axis 96 can be easily inserted on both sides, even if there is little space.

Alternatively, the auxiliary axis 96 could be made longer, so that the punch 93 does not have to be passed through the auxiliary axis 96. Alternatively, the skin axis 4 could also directly with the

Hydraulic cylinders are pushed out. The protruding from the first page part of the main axis 4 can now be subjected to a cleaning and / or a test. For cleaning, the

Small parts cleaner and / or its cleaning tool to the projecting out of the recess 4 'of the support structure 1 main axis 4 out. For the test, the test bench is guided to the projecting out of the recess 4 'of the support structure 1 main axis 4 and the

Crack test performed there. On the second page can now the

Plain bearing in the support structure 1 and / or in the main rocker 24th

be taken out. If the roller battery is secured on the second side with the auxiliary axis 96, the auxiliary axis must 96th

be taken out. Since the roller battery is further secured by the at least one securing device on the support device 1, in particular the Abhebejoch 13, and / or by the main axis 4 on the first side of the support device 1, this is possible. Since the auxiliary axis 96 has a continuous recess, one can reach through the through-going recess behind the auxiliary axis 96 and pull it out. Depending on the force required, this can be done by hand / finger or with a tool. Preferably, the hydraulic cylinder used above for the clean sliding is in two

Operable directions and can also pull out for the

Auxiliary axis 96 can be used. The plain bearing is usually replaced (or cleaned and / or tested) and returned to the

Recess 4 'of the support structure 1 and / or the roller battery 2 introduced. Thereafter, the main axis 4 is again completely in the

Recess 4 'of the main rocker 24 and the support structure. 1

pushed back. This can be done by means of the now arranged on the first page hydraulic cylinder 94. If the roller battery is not perfectly centered, the main axle is inserted

SCOTEC-1-PCT 4 stiff and can cause damage to the plain bearing.

Therefore, the auxiliary axis 96 on the second side is preferably pushed back into the recess 4 'of the support structure 1 and the roller battery 2 / the main rocker 24. As a result, the recess 4 'is centered to the recess 4' of the roller battery 2 and the main axis 4 can now be easily pushed into the recess 4 'of the roller battery 2 and the second side of the support structure 1. At the same time the

Auxiliary axis from the recess 4 'from the second side again

pushed out. Preferably, the diameter of the auxiliary axis 96 is slightly larger than the diameter of the main axis 4, so that the auxiliary axis 96 causes optimal centering. The auxiliary axis 96 can thus both for additional assurance of the roller battery 2 and for better centering of the recesses 4 'of the roller battery 2 and the

Support structure 1 can be used. The process of centering the recesses 4 'and the introduction of the main axis 4 in the prior art often took more than one hour. The process described can significantly shorten this process. However, it is also possible to perform the process without the auxiliary axis 96. The same procedure is repeated analogously in the second direction. The

Main axis 4 is now in a second direction (perpendicular to the

Rope direction and / or to the support structure 1 way) pushed out of the second side of the recess 4 '. The main axis 4 is (only) pushed out so far, so that the main axis 4 on the second side still in the recess 4 'of the support structure 1 and the main rocker 24 is located. At the same time, from the first page, the auxiliary axis in the

Recess 4 'of the support structure 1 and the main rocker 24 pushed. The auxiliary axis is pushed in so far, so that the auxiliary axis is located on the second side in the recess 4 'of both the support structure 1 and the main rocker 24. The protruding from the second side part of the main axis 4 can now be subjected to a cleaning and / or a test. Thereafter, the main axis 4 is again completely pushed back into the recess 4 'of the main rocker 24 and the support structure 1 (in the first direction). At the same time, the auxiliary axis is pushed out of the recess 4 'from the first side. Thus, the entire main axis 4 can be tested and / or cleaned without having to remove them completely from the recess 4 'when the

SCOTEC-1-PCT Checking the main axis 4 shows that this is ok. Otherwise, this is completely pushed out and replaced by a replacement main axis 4.

The cleaning and / or testing of the remaining roller battery 2 will be described below. Preferably, this is the

Main rocker 24 on a first side / extremity in cable direction (for example, the mountain side) of the main rocker 24 with the safety device to the support structure 1, preferably the Abhebejoch 13 moves that at least one of the rollers of the first side in the cable direction of the main rocker 24 against the rope 3 is pressed. As a result, the roller battery 2 and the main rocker 24 rotate about the main shaft 4, and the cable 3 releases the rollers 21 of the opposite second side (e.g., the valley side). This has the advantage that the rope during the cleaning or the

Revision is always performed in at least one of the rollers 21 of the roller battery 2. The at least one rocker 25, axle 22, 23, sliding bearing and / or roller 21, which is (are mounted on the second side of the main rocker 24 (relative to the main axis 4) / can now / cleaning and / or the test and / or exchanged. For this purpose, the at least one rocker 25 of the second side of the main rocker 24 is secured with the further lifting mechanism, preferably the crane, so that the at least one axle 23 is load-free. The at least one axis 23, which supports the at least one rocker 25, can now be removed. Thereby, the mounted on the removed axle 23 rocker 25 can be lowered to the work platform 8, taken apart, the items are cleaned, checked and possibly replaced, reassembled and again with the also cleaned and tested axis 23 back in the main rocker 24 are attached. If the second side in the cable direction of the main rocker 24 has more than one rocker 25, this is done for each rocker 25. The securing device on the first side of the main rocker 24 is moved back again, so that the cable 3 passes back into at least one of the rollers 21 of the second side of the main rocker 24. The same thing is done on the other side. Preferably, this is the main rocker 24 on the second side of the main rocker 24 with the

Safety device so to the support structure 1, preferably the

Abhebejoch 13 moves that at least one of the rollers 21 of the second

SCOTEC-1-PCT Side are pressed in the cable direction of the main rocker 24 against the cable 3. As a result, the roller battery 2 or the main rocker 24 rotates about the main axis 4 and the cable 3 releases the rollers 21 of the opposite first side in the cable direction. The at least one rocker 25, which is mounted on the second side in the cable direction of the main rocker 24, can now be subjected to cleaning and testing. For this purpose, the at least one rocker 25 of the first side of the main rocker 24 is secured with the further lifting mechanism, preferably the crane, so that the

at least one axle 23 is free of load. The same maintenance steps as on the second page will now be on the first page in cable direction

carried out. The safety device on the second side of

Main rocker 24 is moved back again, so that the rope 3 passes back into at least one of the rollers 21 of the first side of the main rocker 24.
