Abstract

The present invention relates to a mobile crane with an undercarriage with a chassis and a superstructure with boom, in particular telescopic boom, the undercarriage having a turntable on which the superstructure is rotatably mounted about a vertical axis of rotation and wherein the undercarriage in the region of the turntable connecting elements for releasable Connection with lateral support units are provided.

Description

  • The The present invention relates to a mobile crane with an undercarriage with a chassis and a superstructure with boom, in particular telescopic boom, wherein the undercarriage has a turntable on which the superstructure is rotatably mounted about a vertical axis of rotation.
  • Such Mobile cranes usually have several axes, at large mobile cranes usually eight or more axles, on which the mobile crane on the road is movable. Due to the current legislation is doing for Road transport allowed a maximum axle load of 12 t. In general, this will be for large appliances with a total weight of up to 100 t driving permits relatively easy and issued quickly. For total weights over 100 t However, these are very expensive or impossible to obtain.
  • One Mobile crane should therefore be for road travel do not exceed a total weight of 100 t. It should be noted that for a given maximum total weight after deduction of all machine parts such. B. Motor, axles, etc. a residual weight for the supporting steel construction remains in crane operation. The design weight for The structural steelwork of the assemblies is distributed over the Boom, the turntable, the vehicle frame, the support and the luffing cylinder. The more weight assigned to an assembly the stronger it can be done. The design weight is depending on the user requirement divided to the individual modules, so that the individual modules maximum be utilized and a homogeneous load table with respect to the discharge and load results.
  • In order to maintain the maximum weight for road travel, it is known to transport individual modules separately and to connect to the mobile crane at the hub. So z. B. the boom with or without rocker cylinder to be transported separately, as is made DE 20 2006 007 486 U1 is known. By separately transporting the boom, the total design weight for the remaining components revolving platform, vehicle frame and support can be used. Furthermore, it has already been envisaged to achieve the country-specific permissible axle loads or the permissible total weight for road transport by dismantling the rear sliding beam box with the rear support bars.
  • Also Other cranes are usually disassembled into individual parts Delivered at the hub and only there mounted. The situation at such cranes such. As stationary cranes or crawler cranes, however not comparable to the mobile crane situation. With stand or crawler cranes are all components anyway brought on transport vehicles to the hub, so that the items just have to make sure that this over Transport vehicles remain transportable.
  • At the Mobile crane, however, the basic unit must be designed that this automatically over the road can be driven to the place of use. In this respect arise for Mobile cranes completely different requirements than others Crane types.
  • task The present invention is now to provide a mobile crane to provide, in which the permissible weight of the Road use used basic unit highest possible load is maintained.

Such a mobile crane has an undercarriage with a landing gear and a superstructure with a boom on, in particular with a telescopic boom, with the undercarriage a turntable on which the superstructure about a vertical axis of rotation is rotatably mounted. According to the invention are now on the undercarriage in the area of the turntable fasteners for detachable connection with lateral support units intended. Through the detachable connection can the lateral support units are transported separately, so that the transport weight of the mobile crane is reduced. The lateral arrangement of the support units has the decisive advantage that the steel structure of the undercarriage can be performed much easier than conventional Support units, which front and rear of the undercarriage are arranged. Such arranged front and rear of the vehicle frame Support units must namely over a stable and thus very heavy steel construction with the relative distant turntable can be connected. The lateral support units on the other hand, they can be arranged directly next to the turntable, so that steel structure weight can be saved here on the undercarriage can.
  • advantageously, Here are the fasteners directly to the steel structure of the undercarriage which carries the turntable arranged. So here are no boxes with side boxes can be connected to the undercarriage, but used a direct Connection of the lateral support units with the turntable pot. This allows the connection areas between the turntable pot and the Abstützholmen, which for power transmission made very solid, removed from the undercarriage and form part of the lateral support units.
  • advantageously, The lateral support units are supported by this in the assembled state directly on the pot plate of the turntable carrying pot. This results in an optimal introduction of force at a minimum design weight of the undercarriage. advantageously, In this case, only pressure forces in the pot plate in crane operation initiated while pulling forces over a separate Verbolzung, which advantageously below the pot plate is arranged to be recorded.
  • Farther Advantageously hooks are provided on the mobile crane, in which the support units can be hung for easier installation are. These hooks prevent in the unloaded state also a lateral tilting away the support units.
  • advantageously, are still the fasteners for releasable connection with the lateral support units within the outer contour arranged the undercarriage. So that's the connection areas, which connect the undercarriage with the support beams and which necessarily outside the outer contour of the undercarriage must be arranged, part of the removable side support units and must so not be transported.
  • advantageously, the mobile crane is alone in the crane operation over the lateral support units can be supported. hereby can dispense with the front and rear support bars and in particular the heavy steel construction, which these with connects the turntable. Advantageously, are the lateral Support units arranged symmetrically to the turntable, to ensure optimal support.
  • advantageously, However, an auxiliary support for mounting a lateral Support provided by means of the boom of the mobile crane. Over a Such auxiliary support, which z. B. in the area of the turntable can be arranged, the mobile crane can be supported, about a lateral support unit by means of the boom to mount the mobile crane itself.
  • In furthermore advantageously, the inventive Mobile crane on a hydraulic axle suspension. advantageously, This hydraulic axle suspension is fixable to the undercarriage to give a certain stability. In further advantageous Way is about the hydraulic axle suspension of the undercarriage movable in the vertical direction.
  • advantageously, the mobile crane according to the invention has two lateral Support units on which he at the hub can be supported. These are over the fasteners releasably connected to the undercarriage of the mobile crane connectable, so that they can be removed for transport. This allows the permissible design weight on the remaining components of the mobile crane are distributed.
  • The The present invention further comprises a lateral support unit with connecting counter-elements for releasable connection with a mobile crane as described above. Such a lateral Support unit can be transported separately and be mounted at the hub to the mobile crane for the Support hub.
  • advantageously, the lateral support unit has a central element on, on which the connection counter elements are arranged, wherein arranged on the central element Abstützholme hinged are. This allows the lateral support units easy to transport by folding the outriggers are and are thus arranged parallel to each other in a line. If the support units are then mounted on the mobile crane the support spars unfolded and the support spar arranged support cylinder extended to the mobile crane so support and the largest possible To ensure supporting surface. advantageously, In this case, a fold-out drive is provided on the support unit, z. B. a hydraulic cylinder.

  • The The present invention further encompasses two methods for Assembly of the lateral support units according to the invention on the undercarriage of a mobile crane.
  • A first method comprises the following steps:
    • - Positioning the lateral support unit on a transport vehicle in the range of the mobile crane, and
    • - Lifting and moving the lateral support unit in the mounting position on the mobile crane by means of the boom of the mobile crane.
  • Here, therefore, the boom of the mobile crane itself is used to bring the lateral support unit in a mounting position on the crane. Advantageously, this is the axle suspension of the mobile crane, in particular the hydraulic Achsfe tion, blocked to ensure a certain stability of the mobile crane.
  • In Further advantageously, the mobile crane via a Auxiliary support supported to a sufficient Stability for mounting the support units to ensure.
  • An alternative method for mounting a lateral support unit on the undercarriage of a mobile crane, however, comprises the steps:
    • - Positioning the lateral support unit on a transport vehicle directly next to the connection area with the mobile crane, and
    • - Approach the lateral support unit to the mobile crane by means of a arranged on the transport vehicle displacement arrangement.
  • The Movement through the displacement arrangement can be different Individual movements must be composed and not purely translational be, so z. B. tilting or hanging the side Include support unit.
  • advantageously, However, when mounting a relative change in height between support unit and mobile crane by a in the Height adjustable axle suspension of the mobile crane causes. Advantageously, the displacement arrangement takes only one linear sideways movement of the lateral support units in front. This allows the displacement arrangement on the transport vehicle be made considerably simpler. Furthermore, an alignability be provided in the longitudinal direction to the positioning to facilitate the support units.
  • The inventive method for mounting a lateral Support unit are advantageously with lateral Support units and carried out on mobile cranes, as described above.
  • Farther The present invention comprises a transport vehicle for a lateral support unit with a displacement arrangement to carry out a process as described above has been.
  • hereby Obviously the same benefits arise as above with respect to the method.
  • The The present invention further comprises a mobile crane, in which the lateral support units over a mounted on the crane cab power lift can be mounted can. Such a mobile crane has an uppercarriage on which a boom can be augered about a horizontal axis is articulated, and a cab for the crane operator, which pivotable about a pivoting device on the superstructure is arranged. According to the invention, the Cabin or the pivoting device a power lift to lift the lateral support unit, so that a means of the Power lift lifted support unit by means of the pivoting device is movable relative to the crane. This makes it possible the without existing pivoting device for the cabin to use for the assembly or disassembly of the mobile crane. One separately delivered to the job site support can so over raised the power lift and the pivoting device moved to the mounting position on the crane and mounted there. The pivoting devices and the power lift enable the Assembly and / or disassembly of a lateral support unit. Such support units advantageously have one Central box, which is connected to the undercarriage and on which supports are provided. These support units can now over the power lift and the pivoting device to be assembled. The invention further comprises a corresponding mobile crane with a means of the power lift and the pivoting device mountable and / or removable side support unit.

  • at the present invention remain boom, turntable, Vehicle frame and luffing cylinder on the mobile crane for road driving assembled. The entire support with the force-inducing Recordings, on the other hand, are not transported by vehicle, but instead on public roads on a separate Move transport unit. The special implementation of the support units, which are detachably connectable to the undercarriage of the mobile crane, ensures that by dismantling the support units as much weight as possible can be removed from the crane. In addition, procedures are provided via which the support units can be mounted, to give the mobile crane its full working capacity. According to the invention can thus to a considerable extent Saved design weight or the saved construction weight distributed to the other components.
  • This is based on the 1a and 1b clarified, with in 1a the embodiment of a turntable and the turntable bearing steel structure according to the prior art is shown. Here is the range of the circulation of the turntable 20 to the receiving points of the supporting spars, which on the vehicle frame 70 are arranged, heavily loaded and partly long. Therefore, this area needs a lot of steel construction weight.
  • The present invention can be considered to rotate the part carrying the slewing ring through 90 ° as shown in FIG 1b is clarified. As a result, on the one hand, the area between the support of the turntable 20 and the receiving points of the supporting spars are significantly reduced, so that even by itself steel construction weight is saved. In addition, the heavily loaded areas 80 , which connect the steel frame carrying the slewing ring with the support beams, are also removed from the undercarriage, since they are not at the same time the connection to the vehicle frame 70 serve. This also allows the permissible vehicle width 90 be respected.
  • Therefor are suitable releasable connection points on the undercarriage provided with the power from the turntable directly into the fasteners with initiate the support beams. The remaining areas the vehicle frame, however, can be weaker be dimensioned, since these are relieved in crane operation, if the wheels are lifted off the ground.
  • An embodiment of an undercarriage 8th a mobile crane according to the invention is in 2a shown. This one has a heavy, the turntable 20 bearing steel construction 25 on which are lighter, primarily for driving purposes the ending steel structures 21 and 22 connect to which the chassis with the wheels 23 is arranged. On the undercarriage 8th are now in the area of the turntable fasteners 102 . 111 and 121 provided for releasable connection with lateral support units. The fasteners are directly on the steel structure 25 of the undercarriage which carries the turntable arranged.
  • In addition, the lateral support units in the mounted state directly on the pot plate 111 support the pot bearing the turntable.
  • The Connecting elements are symmetrical to the turntable on both Side of the undercarriage arranged so that a stable support results. The connecting elements for releasable connection with the lateral support units are within the outer contour of the undercarriage arranged so that they Do not increase the width of the undercarriage during the procedure. In addition, these are the designed as a heavy steel structure Connecting areas with the supporting beams part of the supporting units, so that weight can be saved on the undercarriage.
  • The connection of the lateral support units is off 2 B and 2c seen. The lateral support units have connection counter-elements 100 . 110 and 120 on which with the fasteners 102 . 111 and 121 detachably connectable to the undercarriage of the mobile crane. In particular, there are Verbolzungen 100 . 102 intended. Furthermore, the steel construction of the lateral support units can also be supported flat on the steel construction of the undercarriage, in particular on the pot plate 111 of the turntable carrying pot.
  • The lateral support units have a central element 30 on, on which the connecting counter-elements are arranged. At the central element 30 are still two support beams 32 folded out. For this purpose, a fold-out drive in the form of hydraulic cylinders is provided. For transport, the supporting spars can be folded so that the two supporting spars and the central unit are aligned in a common plane. At their ends, the support spars 32 while supporting cylinder 31 on which the crane can be supported. Furthermore, the support beams can be telescoped.
  • The following will now be based on the 2a to 2c the connection of the lateral support units with the undercarriage 8th of the mobile crane according to the invention explained in more detail. There are at the turntable 20 supporting steel structure 25 of the mobile crane bolting elements 102 arranged, which with Gegenverbolzungselementen 100 at the central box 33 the lateral support unit via bolts 101 can be bolted. These are on both sides of the undercarriage 8th two bolt connection elements each 102 symmetrical to the slewing ring 20 arranged. Furthermore, there are hooks 121 above the bolt connection 102 on the undercarriage 8th of the mobile crane, in which the lateral support units via bolts 120 can be hung. In addition, the lateral support units are supported by the sheet metal 110 on the side edge of the pot plate 111 the turntable pad.
  • In the crane operation, the vertical forces that must be transmitted between the support units and the turntable pot, of the respective bolt connections 100 . 101 . 102 transfer. Furthermore, this bolt connection primarily serves to transmit tensile forces in crane operation. Of course, however, all other absorbable from the bolt connections forces can be transmitted, which, however, occupy only a minor role here. To record the moments occurring during crane operation via a pair of forces, is still the connection between the pot plate 111 the turntable pad and the sheet metal 110 of the central box 33 the lateral support unit provided. Here, only compressive forces are transmitted in crane operation. Thus, in this case, the connection between the sheets 111 and 110 which clash, are formed. A further complicated bolt connection can thus be saved. Another advantage of this arrangement is that the existing anyway strong pot plate of the turntable pad can be used without additional strong sheets are needed. In addition, a short power flow is available.
  • So that the support unit can not tip over in the unloaded state, this is over the bolts 120 in the hook 121 on the undercarriage 8th hooked. The suspension of the support unit is used in the hooks 121 also the easier assembly.
  • When mounting the support unit are first the bolt holders 100 and 102 pushed on support unit and undercarriage. As a result, the support unit assumes a defined position in the longitudinal direction, so that an attachment of the support unit to the hook 121 becomes possible. Then the support unit is positioned so that the bolts 101 the bolt connection can be inserted. These are drives for the bolts 101 provided, over which these are moved. The bolts are thus externally driven and not manually inserted. A targeted phase on the bolt facilitates the assembly.
  • In 2c is now the support unit over the Central box 33 mounted on the undercarriage, with the supporting spars 32 already unfolded. The folding drive in the form of a hydraulic cylinder is not shown for clarity.
  • If the side elements are mounted, the support bars can be folded out. The support units from the two support beams 32 and the central element 30 , which forms the complete connection area between the steel ring supporting the slewing ring and the support beams, thereby form an assembly which can be handled as a whole. However, a further dismantling of the support units could also be provided. The support units can now be transported either individually or in pairs to a trailer.
  • The mounting of the support units can be carried out by means of two methods:
    • Case A: by the crane itself with its own boom,
    • Case B: by a suitable auxiliary device.
  • Case A is in 3a and 3b shown. Here, the assembly is done by the crane itself with its own boom 2 without an auxiliary crane The boom is aufippbar on a hydraulic cylinder on the superstructure 1 arranged on the mobile crane, which on the turntable of the undercarriage 8th is mounted rotatably about a vertical axis. As a basis for this case, it should be noted that the crane still has no ballast and no main support. Will be in this state, the superstructure 1 with the heavy boom 2 turned, the center of gravity of the superstructure changes very quickly. The method according to case A is thus as follows:
    • 1. Mobile crane and trailer are positioned to each other.
    • 2. The hydraulic axle suspension is switched to "blocked".
    • 3. In order to ensure the permissible axle loads and the stability, an auxiliary device 10 be attached to the crane or be. This device may act as an additional support unit, and be telescopic or hinged, for example. Also, the device may be located within the vehicle width.
    • 4. For picking up the support units 30 The trailer uses its own boom. For this application, a special payload table, backed by the LMB, can provide the required safety so that the support unit can be mounted on one side of the crane. The support unit on the opposite side is mounted analog. If necessary, the already attached Abstützholme 32 placed in a corresponding position and by means of support cylinder 31 be supported on the ground. This achieves a higher tilting safety.

    It is also possible that the trailer is repositioned to the mobile crane.
  • Case B is in 4a and 4b shown. Here, the installation is carried out by a suitable auxiliary device, wherein the quick and easy installation of a mounting device 11 which is used in road transport on the transport vehicle 95 (and thus not on the mobile crane) is transported and so the weight distribution on the mobile crane is not further burdened. The mounting device 11 has a displaceable mechanism for positioning the support units 30 on the mobile crane. In this case, the Monatgevorrichtung 11 advantageously detachable on the transport vehicle 95 be mountable. A transport vehicle can be easily equipped for transporting and mounting the support units with the mounting device. The assembly takes place without the use of the own boom of the mobile crane in the following steps:
    • 1. Mobile crane and trailer are positioned side by side.
    • 2. The hydraulic axle suspension is switched to "blocked".
    • 3. The support units 30 can be attached to the turntable via a sliding mechanism from the trailer. The sliding mechanism accommodates the respective support unit to be mounted and brings them into the mounting position. The support units are doing over their central box 33 from the mounting device 11 held. The movement of the mounting device can be composed of various individual movements (tilting, hanging) and does not have to be purely translational. For the sake of simplicity, the purely translatory movement is preferable and the design must be designed accordingly. In addition, a mobility of the mounting device may be provided in the longitudinal direction, through which a not completely parallel alignment of the transport vehicle 95 or the support units can be compensated for mobile crane.
    • 4. Any lifting movement that may be required can be taken over by the height-adjustable axle suspension of the mobile crane.
    • 5. Thereafter, the positive connection between turntable pot and support unit, z. B. via bolts.
    • 6. The second support unit is mounted analogously after repositioning of mobile crane and trailer side by side.
  • For the drive of the sliding mechanism can be a separate source of energy be provided or it will be connected to the mobile crane.
  • Both for Case A and Case B applies:
    Between the wheels and the support in the folded state, a corresponding distance is provided in order not to have to dismantle the support units when driving on the construction site. Due to the distance, the wheels can hit and the crane can be moved on the construction site.
  • The Assembly and disassembly of the lateral support units will monitored by the crane control independently of the assembly process. The monitoring is carried out as necessary and possible.
  • In 5 Another Ausführungsbesipiel the mobile crane according to the invention is shown, with mounted support units 30 and 40 , The support units 30 and 40 each have a central box, which with the undercarriage 8th the mobile crane is connected. For this purpose, connections are provided on the central box, which can be quickly connected to the undercarriage. The connections may be mechanical, hydraulic, electrical, etc. At the central box are support bars 32 provided, which may be pivotable and / or telescopic. At the outer end of the supports 32 are supporting cylinders 31 provided, which are extended for supporting the mobile crane.
  • At the in 5 shown above second support unit 40 are already swung out the supports and telescoped. In the first support unit shown below 30 the support units are still in their transport position, in which the supports 32 not yet swung out.
  • 6 now shows an embodiment of the mobile crane according to the invention with a pivoting device 4 over which the driver's cab 3 with respect to the vertical axis of Verschenkachse 28 opposite the uppercarriage 1 the mobile crane can be pivoted and moved over the telescopic extension of the pivoting device in the radial direction. In this case, the power lift is on the cabin side end of the pivoting device 5 provided, which thus also pivots about the pivoting device and can be moved in the radial direction. Pivoting device and power lift 5 thus form an auxiliary crane, over which one on the transport vehicle 60 stored crane part can be raised and moved.
  • 7 now shows the assembly of the first lateral support unit 30 , The support unit is on the means of transport next to the mobile crane on the side where the cabin 3 and thus the power lift 5 located, driven. The boom 2 is in its transport position. The power lift 5 is now by pivoting and telescoping the pivoting device 4 above the connection point with the lateral support unit 30 positioned and connected.
  • The support unit 30 is now lifted by means of power lift from the transport. Again, the attachment point to the position of the center of gravity of the support unit 30 positioned so that the mounting of the support unit is facilitated. By pivoting and telescoping is now the support unit 30 brought into mounting position, drained and then hung at the joints. The support unit 30 gets on the undercarriage 8th mounted and the power lift is released again. Subsequently, the quick coupling, not shown, for example, for the hydraulics, electrical or pneumatic closed.
  • Because the superstructure 1 of the mobile crane due to the heavy boom 2 Without a support can not be turned, the mobile crane is now, as in 8th shown, first on the already mounted first support unit 30 supported on one side, so that it receives one-sided sufficient stability. Now the superstructure can 1 be pivoted so that the boom 2 swings over the support. As a result, enters the pivoting and telescoping cabin 3 with the power lift on the other side of the crane, so that the power lift for mounting the second support unit 40 can be used on the opposite side. Also the second support unit 40 will now, as in 8th shown mounted in the same way as the first support unit 30 ,
  • The disassembly of the two lateral support units then takes place in the reverse order. So it is first the second support unit 40 disassembled by means of the power lift and the pivoting device while the crane is still on the first support unit 30 supported on one side. Then the superstructure with the boom 2 pivoted so that the pivoting cabin is moved to the other side with the power lift. This is the boom 2 positioned for reasons of stability so that it is aligned substantially parallel to the longitudinal axis of the mobile crane forward, that is, that it is substantially in its transport position. Now also the remaining first lateral support unit 30 be dismantled by means of the pivoting device and the power lift.
