Description

Frame of a mobile work machine with a transport magazine

The subject matter of the present invention is a frame of a mobile working machine, in particular a mobile thick matter pump, which has a lateral loading surface section aligned parallel to a longitudinal direction of the frame. The framework comprises a transport magazine extending along the longitudinal direction.

Mobile work machines regularly include such a frame structure, which can be placed directly on a chassis of a truck via a mounting frame or directly, or which can itself form the chassis or at least part of the chassis. Such frameworks regularly include a loading area on which the superstructures required for the respective working machine can be fixed. An elongated transport magazine extending along the longitudinal direction of the frame can be parked on a lateral loading area area, in which objects and/or materials such as operating resources or add-on parts that are required for the work operation can be stored and transported.

Such a frame can be used, for example, in fire-fighting vehicles, in which a fire-fighting water tank, a fire-fighting water discharge device and a fire-brigade ladder can be arranged on a central loading area section of the frame. Firefighting equipment can be stored in the transport magazine.

In the case of a mobile thick matter pump, a structure as described above positioned on the frame can be formed, for example, by a fold-out thick matter distributor mast arranged centrally on the loading area. along the A sludge line is usually routed through the sludge distributor boom to deliver sludge pressurized by a sludge pump unit. If a desired application location cannot be reached through the foldable sludge distributor boom, it may be necessary to connect additional sludge lines ( sludge pipes or hoses ) to the sludge pump unit or to be connected to the existing high-viscosity line to extend it. For this purpose it is known, for example from EP 1 117 883 or from DE 198 50 009, to provide a transport magazine positioned on a lateral loading area section with a plurality of compartments for receiving thick matter lines, the transport magazine being about an axis parallel to a vertical axis of the chassis is designed to be rotatable and can also be pivoted about tilting axes aligned parallel to the loading area from a transport position into a removal position.

In many situations, however, the solutions known from this prior art do not allow optimal access to the objects stored within the transport magazine and also require increased operating effort. Against this background, it is the object of the present invention to provide a framework for a mobile machine that at least partially avoids the above disadvantages.

This problem is solved with the features of the independent claims. Advantageous configurations are described in the dependent claims.

Accordingly, the invention relates to a frame of a mobile work machine, in particular a mobile high-viscosity pump, which has a lateral loading surface section aligned parallel to a longitudinal direction of the frame. The The frame also includes a transport magazine, which can be moved from a transport position that at least partially overlaps the side loading area section into a removal position located next to the transport position. The frame also has an adjusting device for moving the transport magazine between the transport position and the removal position, which comprises first linear kinematics for moving the transport magazine along a first axis and second linear kinematics for moving the transport magazine along a second axis.

First, some of the terms used in the present description are explained. The framework is designed to be connected to the chassis of a mobile working machine. The framework itself can also form the chassis or part of the chassis. The work machine can in particular be a mobile thick matter pump (truck-mounted concrete pump). It is also possible that the framework can be detached from the chassis of the mobile working machine in order to be parked on an underground and operated in a stationary manner.

The transport magazine is used to transport objects and/or materials such as operating resources or attachments that are required for the work operation. For this purpose, it can have one or more at least partially walled compartments in which the transported goods are protected from external influences. It is also possible that the transport magazine is formed by a transport frame. In one embodiment, the transport magazine is designed to transport high-consistency lines. Suitable pipe or Hose segments to be understood that are designed to be placed together. With the mobile sludge pump, an existing sludge line can be lengthened. In the transport position, the transport magazine at least partially overlaps the lateral loading area section. This means that the transport magazine is positioned at least partially in the vertical direction above the side loading area section. It is not absolutely necessary for the transport magazine to be able to be placed on the side loading area section. Also included in the concept of the invention is an embodiment in which the transport magazine is permanently carried by the adjusting device in the transport position.

In the transport position, the transport magazine extends along the longitudinal direction of the lateral loading surface section. A longitudinal extension of the transport magazine can be more than 0.2 times, preferably more than 0.4 times, more preferably more than 0.6 times the longitudinal extension of the frame. The transport magazine can, for example, have a length between 2 m and 6 m, preferably between 3 m and 5 m, more preferably between 3.5 m and 4.5 m.

The transport magazine can be moved from the transport position to the removal position by means of the positioning device. The removal position is located next to the transport position, so that the transport magazine can be moved outwards from the transport position, in particular transversely to the longitudinal axis of the chassis, in order to reach the removal position. The removal position is also regularly located below the transport position. After a sufficient movement transverse to the longitudinal axis, the transport magazine can be moved down, for example, in order to place it on the floor. However, it is also possible for the removal position to be above the transport position, for example if an unloading process takes place from a level above the loading area. The adjusting device can be designed to To position transport magazine in a plurality of removal positions. In this case, the transport magazine can therefore be positioned at a position within a removal area which is formed by the plurality of removal positions.

In the context of the invention, it was recognized that the first linear kinematics and the second linear kinematics, which can preferably be controlled independently thereof, can be implemented in a structurally simple and space-saving manner and are also significantly more user-friendly and flexible than the solutions previously known from the prior art. In particular, a transport magazine parked on the side loading area section can be lifted off the loading area by a linear displacement along the second axis, while the transport magazine can be moved laterally beyond the loading area by a subsequent linear displacement along the first axis. If the transport magazine completely releases the lateral loading surface section after the lateral movement, the transport magazine can then be flexibly lowered to a desired height or even completely to the ground by moving it again along the second axis, in order to enable the transported goods stored therein to be easily removed .

The first axis may be a substantially horizontally oriented axis and the second axis may be a substantially vertically oriented axis. It is also possible for the first axis to enclose an angle of between 0° and 15°, preferably between 0° and 5°, with the horizontal. The second axis can enclose an angle in the range between 0° and 15°, preferably between 0° and 5°, with the vertical. The adjusting device can be set up to place the transport magazine either on the side loading area section or to lift it off the side loading area section by means of a linear displacement along the second axis. In this configuration, the side loading area section can be designed accordingly to carry the transport magazine. The adjusting device can also be designed to move the transport magazine sideways over the side loading area section by means of a linear displacement along the first axis, so that the transport magazine completely releases the side loading area section. In addition, the adjusting device can be set up to move the transport magazine upwards and/or downwards by means of a linear displacement along the second axis, the latter in particular for placing the transport magazine on a substrate.

In one embodiment, the adjusting device is set up to lower the transport magazine in a controlled manner, utilizing the force of gravity of the transport magazine. In addition, the adjusting device is preferably set up to carry out the controlled lowering without the conversion of external energy into kinetic energy transmitted to the transport magazine. The term "external energy" refers to forms of energy that are supplied to the actuating device from the outside, for example hydraulically, pneumatically, electrically or mechanically, and which are converted into a movement of the transport magazine. If no such external energy is used, but gravity alone, for the controlled lowering of the transport magazine is used, it is in particular not necessary for an internal combustion engine to be kept running to supply the actuating device with energy during the lowering process. material can be saved. In the case of adjusting devices known from the prior art, in which the transport magazine is pivoted about a longitudinal axis, however, a hydraulic pressure must usually be permanently maintained by means of a hydraulic pump supplied with energy by an internal combustion engine in order to enable controlled lowering of the transport magazine.

The adjusting device can have a hydraulic lowering mechanism, which preferably includes a hydraulic valve for controlling and/or blocking a hydraulic fluid flow. A further lowering of the transport magazine can preferably be prevented by closing the hydraulic valve. In one embodiment, the hydraulic valve can be designed to be switchable manually, for example by means of a lever. Alternatively or additionally, a device for initiating a gradual lowering of the transport magazine can be provided. The device can be set up to lower the transport magazine by a predetermined height by suitable actuation of the lowering mechanism. The predetermined height can, for example, correspond to the distance between two adjacent rows of compartments of the transport magazine, provided the transport magazine has such rows of compartments. The positions that the transport magazine occupies in each case can be regarded as removal positions within the meaning of the present description. When unloading the transport magazine, it can first be provided that a first row of compartments located at the bottom in the transport magazine is lowered to a working height that is optimal for the operating personnel for unloading. If, for example, thick matter lines have been unloaded from the first row of compartments, the device described above can be actuated in order to lower the transport magazine so far that a second row of compartments adjoining the first row of compartments is at the optimum working height. The unloading of This makes the transport magazine significantly more convenient. A controlled and in particular gradual lowering was not possible with previous solutions known in the state of the art. Rather, it was customary in previously known solutions to move the transport magazine with the engine running by means of a hydraulic drive in one go from a transport position to a removal position and then switch off the engine and the hydraulic drive.

In one embodiment, the transport magazine includes a quick-release point, by means of which the transport magazine can be releasably connected to the adjusting device. This makes it possible to detach the transport magazine from the positioning device after it has been set down on the ground. The transport magazine can then be brought to a desired location using a separate lifting device (for example using a forklift). In addition, several transport magazines with different contents, for example with different types of high-viscosity lines, can be kept ready and a desired transport magazine required for an application can be connected to the adjusting device. If no objects or materials need to be transported with the frame, the frame can also be used without a transport magazine to save weight. If the transport magazine is damaged, it can also be easily replaced.

The transport magazine can have a longitudinal extension along which the objects to be transported can be introduced into and removed from the transport magazine, the transport magazine being connected to the positioning device in such a way that an imaginary two-sided extension of the transport magazine along the longitudinal extension (in particular in the removal position) the positioning device does not cut . In one embodiment, a connection area in which the Transport magazine is connected to the adjusting device, from one and preferably from both longitudinal ends of the transport magazine at a distance along the longitudinal extent of at least 50 cm, preferably at least 1 m, more preferably at least 2 m. The distance along the longitudinal extent can for example be at least one tenth of the longitudinal extent, preferably at least one fifth of the longitudinal extent of the transport magazine, with the connection area being particularly preferably positioned centrally on the transport magazine in relation to the longitudinal extent. This configuration leaves enough space in the area of the longitudinal ends to be able to conveniently load and unload the transport magazine via both longitudinal ends. In contrast, adjusting devices already known from the prior art are often so expansive that objects to be transported can only be loaded and removed at one end of the transport magazine. In particular when transporting objects with a large longitudinal extent (such as high-viscosity lines), the features mentioned above offer clear advantages.

In one embodiment, the adjusting device comprises a supporting element fixed to the frame, an adjusting element that can be displaced relative to the supporting element along the first axis, and a lifting element that can be displaced relative to the actuating element along the second axis and is designed to fasten the transport magazine. The first linear kinematics are preferably designed to move the actuating element relative to the support element. In addition, the second linear kinematics are preferably designed to move the lifting element relative to the actuating element. The first linear kinematics can be designed, for example, as extendable scissor kinematics or as extendable telescopic kinematics. The lifting element can be guided by means of a linear guide on the actuating element. The first and/or second linear kinematics can be designed to be driven hydraulically, electrically or mechanically.

In a preferred embodiment, a container (for example a trough) which is preferably open at the top is fastened to an upper side of the transport magazine. Tools in particular can easily be inserted and removed from these. The space available above the transport magazine is thus optimally utilized. Such a container cannot be used with previously known adjusting devices in which the transport magazine is pivoted about a longitudinal axis, since the tools would fall out when the transport magazine was rotated or would at least move uncontrollably in the container and collide.

The framework can have a thick matter distribution mast and a central loading area section which is positioned next to the side loading area section in relation to a transverse direction of the framework, the thick matter distributing mast being able to be placed on the central loading area section. In particular, two lateral loading surface sections can be present, which enclose the central loading surface section between them. The framework can also have a sludge pump unit.

In one embodiment, the framework has two front support legs, two rear support legs and an upper framework positioned above the framework by means of the support legs and extending in a longitudinal direction and in a transverse direction of the framework. The support legs preferably each have a first end area connected to the frame and a second end area connected to the upper frame, with at least one of the support legs in the first end area being connected to the frame by a first pivot connection. frame and is connected in the second end area by a second pivot connection to the upper frame. The upper frame is preferably part of the support element and can serve to accommodate and/or guide the actuating element. In particular, the upper frame can be designed to accommodate and/or guide a telescopic unit. By at least one of the support legs by a pivot connection both in the first end and in the second end with the frame or. is connected to the upper frame, torsions that occur, for example, during the operation of a mobile concrete pump in the frame are not passed on to the upper frame, or at least to a significantly lesser extent. This is particularly advantageous when the upper frame is designed to hold or guide a telescopic unit, since twisting, which in this case can in principle be passed on from the frame to the upper frame, would significantly impede the functional ability of the telescopic kinematics.

The embodiment described above may have independent inventive content, in particular without the frame having a side loading area section aligned parallel to a longitudinal direction of the frame and a transport magazine which can be moved from a transport position that at least partially overlaps the side loading area section to a position next to and below the transport position located removal position is movable, wherein the frame has an adjusting device for moving the transport magazine between the transport position and the removal position, which comprises a first linear kinematics for moving the transport magazine along a first axis and a second linear kinematics for moving the transport magazine along a second axis. In one embodiment, one or both of the pivot connections is configured to permit rotation about an axis parallel to the longitudinal axis of the framework. In particular, one or both of the pivot connections can have a ball and socket joint.

Provision can be made for the front support legs to be connected to one another in their second end region by a cross member. Provision can furthermore be made for the front support legs to be connected in their second end region to a respective first end of a respective diagonal beam, with the respective other ends of the two diagonal beams being connected to one another and to the framework. In this case, the cross member and the diagonal members can form a bearing block of a framework. The connection of the diagonal support to the frame can be realized by a swivel connection, which can in particular allow a rotation about an axis parallel to the longitudinal direction of the frame. This swivel connection can also have a ball and socket joint.

The subject matter of the present invention is also a mobile sludge pump which has a frame according to the invention.

Further advantages and refinements of the invention result from the dependent claims, the description and the accompanying drawings.

It goes without saying that the features mentioned above and those still to be explained below can be used not only in the combination specified in each case, but also in other combinations or on their own, without departing from the scope of the present invention. The invention is illustrated by exemplary embodiments in the drawings and described in detail below with reference to the drawings.

FIG. 15 shows a cross-sectional view of the part of the adjusting device shown in FIG.

FIG. 1 shows a three-dimensional view of a first embodiment of a framework 13 according to the invention. The frame 13 forms the chassis of a mobile concrete pump and comprises a loading area which extends in the longitudinal direction of the frame 13 and has a central loading area section 10 and two lateral loading area sections 14 . At a front end of the framework 13 there is a mast block 12 which is designed for the rotatable mounting of a concrete placing mast. The concrete placing boom is not shown in FIG. 1 for the sake of clarity. The concrete placing boom can be placed on the central bed section 10 . The lateral loading surface sections 14 are positioned on both sides in the transverse direction of the frame structure next to the central loading surface section 10 .

A transport magazine 15 is placed on each of the lateral loading area sections 14 . In the state shown, the transport magazines 15 are in the transport position. The transport magazines 15 have a plurality of compartments, into each of which a concrete pipe 16 is inserted. The compartments are closed in Figure 1 by protective grilles, so that the concrete lines 16 are not visible. A concrete discharge container 28 is also positioned in a rear area of the loading area. Concrete poured into the feed container 28 can be conveyed through concrete pipes and hoses by means of a concrete pump unit, which cannot be seen in the figure, in order to be discharged at a desired location.

Also arranged on the central loading area section 10 is an adjusting device 17 which is used to move the transport magazines 15 from the transport position into a removal position. The adjusting device 17 is connected to the transport magazine 15 in a connecting region 20 that is positioned centrally in relation to a longitudinal direction of the transport magazine 15 . The functioning of the adjusting device 17 is explained with reference to FIGS.

FIG. 2 shows a rear view of the framework 13 of FIG. In this view it can be seen that the adjusting device 17 comprises a carrying element 18 fixedly connected to the frame 13 , an adjusting element 19 designed to be movable relative to the carrying element 18 and a lifting element 22 designed to be movable relative to the adjusting element 19 . The transport magazine 15 is firmly connected to the lifting element 22 in the connection area 20 .

The adjusting element 19 is connected to the supporting element 18 via telescopic kinematics and can be extended out of the supporting element 18 along a horizontal axis. When the actuating element 19 is extended, the lifting element 22 is moved sideways outwards together with the transport magazine 15 starting from a longitudinal axis of the frame, so that the transport magazine 15 releases the lateral loading surface section 14 . In the state shown in FIG. 2, the side loading area section 14 on the left-hand side of the frame is completely released. The lifting element 22 can then be lowered together with the transport magazine 15 to a desired height (cf. FIG. 3).

FIG. 3 shows a rear view of the framework of FIG. 1 in a state after the transport magazine 15 has been lowered to the ground. During the lowering, the lifting element 22 together with the transport magazine 15 fastened to it is moved downward relative to the adjusting element 19 . For this purpose, the lifting element 22 is connected to the actuating element 19 via a hydraulic linear guide. In the present case, the lifting element 22 is lowered relative to the adjusting element 19 in a controlled manner by utilizing the force of gravity acting on the lifting element 22 . A lowering caused by gravity is accompanied by a corresponding flow of oil within the hydraulic linear guide.

The hydraulic linear guide also has a locking mechanism which is designed to prevent further lowering of the transport magazine 15 and to position the lifting element 22 at a desired height relative to the adjusting element 19 . The locking mechanism can have a hydraulic valve to block the flow of oil. Blocking the flow of oil prevents the transport magazine 15 from lowering further. The hydraulic valve can be designed to be switchable manually, for example by means of a lever. Alternatively or additionally, a device for initiating a gradual lowering of the transport magazine can be provided, which is designed to actuate the locking mechanism after the lifting element 22 has been lowered by a predetermined height. Starting from the state shown in FIG. 2, the transport magazine 15 can first be lowered to a height with the aid of the device for initiating a gradual lowering, which enables easy removal of tubes from a bottom row of compartments 35 (see FIG. 2). through a beta By means of the device for initiating a gradual lowering, the transport magazine 15 can then be further lowered by a height which corresponds to the distance between two adjacent rows of compartments. In this way, the second row of compartments from below 36 (see FIG. 2) can be unloaded in a convenient manner.

Due to the central arrangement of the connecting area 20 in relation to the longitudinal direction of the transport magazine 15 (cf. FIG. 1), after lowering, thick material pipes or -Hosees are removed from the transport magazine 15.

FIGS. 4 to 7 show another embodiment of a frame 13 according to the invention in a rear view. This embodiment differs from the embodiment of FIGS. 1 to 3 in particular in the configuration of the actuating device 17 . The functions of the remaining elements are essentially the same, so they are provided with the same reference symbols and are not explained again in detail.

In this embodiment too, the frame 13 forms part of a chassis of a mobile concrete pump which stands on the substructure 21 . In this view it can be seen that the transport magazine 15 has a plurality of compartments in which thick matter lines 16 are stored. The compartments form a plurality of rows of compartments arranged one above the other. In this embodiment too, the adjusting device 17 has a supporting element 18 which is fixed to the frame, an adjusting element 19 designed to be movable relative to the supporting element 18 and a lifting element 22 which can be displaced relative to the adjusting element. In contrast to the embodiment of FIGS. 1-3, the actuating element 19 is mounted on the support element 18 with the aid of scissor kinematics. For this purpose, the support element 18 comprises (see FIG. 6) a support mast 51 which is firmly connected to the framework 13 and is provided with a linear guide 52 . The adjusting element 19 has a support mast 53 which is also provided with a linear guide 54 . In the present case, the linear guides are designed as oblong holes. The scissor kinematics also includes a first scissor arm 30 which is attached at its first end in an articulated manner to the support mast 51 and at its second end is guided in a sliding manner in the slot of the linear guide 54 . A second scissor arm 31 is attached at its first end in an articulated manner to the support mast 53 and at its second end is slidably guided in the slot of the linear guide 52 . The scissors kinematics are actuated by means of a hydraulic cylinder 33 . As in the embodiment of FIGS. 1 to 3, the lifting element 22 is connected to the actuating element 19 by means of a hydraulic linear guide.

The sequence of FIGS. 4 to 7 illustrates the movement of the transport magazine 15 from the transport position (see FIG. 4) into a removal position (see FIG. 7). First, the transport magazine 15 is raised by a corresponding movement of the lifting element 22 relative to the actuating element 19 vertically upwards along the arrow 34 in order to lift the transport magazine 15 from the lateral loading area section 14 (see FIG. 5). The scissor kinematics can then be actuated in order to move the actuating element 19 together with the lifting element 22 and the transport magazine 15 attached to it sideways (see arrow 29 in FIG. 6) outwards, so that the transport magazine 15 completely releases the lateral loading area section 14. Finally, the transport magazine 15 can be lowered along the arrow 24 until it is placed on the base 21 (see FIG. 7). FIG. 8 shows an alternative embodiment of a frame according to the invention in a rear view. In this embodiment, the lateral loading area section 14 is formed by a free space above the chassis, which the transport magazine 15 occupies in the transport position. The transport magazine 15 is permanently held in the transport position by the adjusting device 17 . The lifting element 22 can be moved relative to the adjusting element 19 by means of a chain drive 40 . In addition, the embodiment of FIG. 8 has fastening elements 41 for attaching a container into which tools can be placed. Otherwise, the embodiment of FIG. 8 is comparable to the embodiment of FIGS.

FIG. 9 shows the adjusting device 17 of the embodiment of FIGS. 1 to 3 in an enlarged three-dimensional view. FIG. 10 shows the adjusting device with the adjusting element 19 fully extended on one side. In the views of FIGS. 9 and 10 it can be seen that each of the adjusting elements 19 has two telescopic units 192 which can be extended to the side relative to the support element 18 . This takes place via a hydraulic extension cylinder 194 which is mounted centrally on the support element 18 and is designed to extend and retract an extension element 193 in the lateral direction. The extension element 193 is in turn firmly connected to the two telescopic units 192, so that the telescopic units 192 can be extended or retracted to the side together with the extension element 193 by actuating the extension cylinder 194. to be retracted . In addition, two vertically aligned guide columns 195 are fixed to the push-out element 193 , on which the lifting element 22 is mounted. The lifting element 22 can be extended vertically downward relative to the guide columns 195, which is explained in detail in connection with FIGS. FIG. 11 shows the support element 18 in an enlarged view in an operating position. FIG. 12 shows the support element in a maintenance position. In the views of FIGS. 11 and 12 it can be seen that the support element 18 has an upper frame 181 which is connected to two rear support legs 182 and two front support legs 183 in the operating position. The upper ends of the front support legs 183 are also connected to one another by a crossbeam 189 and additionally connected to the framework 13 by a respective diagonal beam 187 . The cross beam 189 forms a bearing block together with the diagonal beams 187 .

The upper frame 181 is essentially rectangular and comprises two telescopic receptacles 179 for receiving the telescopic units 192 of the adjusting elements 19 both on its rear side (relative to the frame 13 ) and on its front side.

The support legs 182 , 183 and the diagonal supports 187 are used to fasten the upper frame 181 to the frame 13 . The rear support legs 182 can be connected to the upper frame 181 by means of detachable bolt connections 186 . On the upper side of the crossbeam 189 the upper frame 181 is pivotably mounted about a transverse axis in a region above the front support legs 183 by means of articulated connections 185 . By loosening bolt connections 186, the upper frame 181 can therefore be pivoted from the operating position of FIG. 11 to the maintenance position of FIG.

To carry out the pivoting movement, the support element 18 comprises a hydraulic cylinder 188 which is articulated on the one hand to the upper frame 181 and on the other hand is firmly connected to one of the diagonal supports 187 . The attachment point of the hydraulic cylinder 188 on the frame 181 is relative to the pivot axis of the articulations 185 in the longitudinal direction of the staggered frame 13 so that the upper frame 181 can be pivoted relative to the support legs by movement of the hydraulic cylinder 188 .

The rear support legs 182 are firmly connected to the frame 13 on their underside. The front support legs 183 are connected at their underside to the frame 13 by means of articulated connections 184 . The articulations 184 include ball joints that allow pivotal movement of the support legs

Allow 183 relative to the frame 13. In this way, twisting of the frame 13 that can occur during operation is not transferred to the upper frame 181, or at least to a significantly lesser extent. The diagonal beams 187 are also connected by means of such a joint

184 connected to the frame. To further reduce the transmission of torsion, one of the front support legs 183 is connected at its top to the cross member 189 by means of a pivot connection 184 having a ball and socket joint. This support leg 183 is therefore a pendulum support in which tensile and compressive forces are only transmitted along the longitudinal axis.

FIGS. 13 and 14 show side views of the guide columns 195 and of the lifting element 22 mounted thereon. In FIG. 13, the lifting element 22 is in a retracted position. In FIG. 14, the lifting element 22 is extended downward relative to the guide columns 195 . The lifting element 22 has a lifting frame 191 , at each of whose lower corners (in the area 200 , see FIG. 15 ) an adjusting chain 196 is fastened. The adjusting chains 196 can be lowered and raised by a pulling mechanism located in the guide columns 195 . This is explained in connection with FIG. 15, which shows a cross-sectional view of the guide column 195 on the right in FIG. A chain roller 197 is rotatably mounted within the guide column 195 . In addition, inside the guide column 195 there is an actuating cylinder 198 and a rotatably mounted chain roller 197 . The actuating cylinder 198 moves the linking roller 197 in the vertical direction relative to the guide column 195 . The adjusting chain 196 is guided around the chain roller 197 . One end of the adjusting chain 196 is connected to the lower end of the guide column 195 at the connection point 199 . The other end of chain 196 is connected to lifting frame 191 at connection point 200 . If the chain roller 197 is moved downwards relative to the guide column 195, starting from the position shown in Figures 13 and 15, the end of the positioning chain 196 connected to the lifting frame 191 is lowered by a corresponding distance until the extended position shown in Figure 14 Position of the lifting frame 191 is reached. By moving the chain roller 197 upwards in the opposite direction, the lifting frame 191 is correspondingly raised again.

The lifting element 22 also has a lifting slide 201 which is designed to be movable in the vertical direction relative to the lifting frame 191 . For this purpose, the lifting carriage 201 is connected in a connecting area 205 to two carriage chains 204, which are guided over deflection rollers 202 attached to the lifting frame 191 and each have their other end attached to a connecting rod 203, which in turn is firmly connected to the guide columns 195. When the lifting frame 191 moves downward relative to the guide columns 195 , the section of the carriage chain 204 between the deflection rollers 202 and the lifting carriage 201 lengthens, so that the lifting carriage 201 is lowered relative to the lifting frame 191 .

Due to the construction described above, an adjustment path of the lifting carriage 201 relative to the guide columns 195 can be achieved which is four times larger than that Adjustment path of the actuating cylinder 198 . The overall height of the lifting element 22 can be significantly reduced in this way while at the same time having large vertical displacement paths. A quick-release point for the detachable attachment of a transport magazine 15 is located on the lifting carriage.
