bolt 29 which extends away from one end of the beam and can be inserted into a fitting bore 30 of the vehicle body 18 is. As soon as the fitting bolt 29 is seated in the fitting bore 30, the low-friction plates 5 or the rollers are 20 of the goods vehicle 1 on the low-friction plates 19 or the roller tables 20 of the vehicle body 18 aligned.

Fig. 8 shows a locking mechanism 31, which on Carrier 6 is attached to the truck 1 with the Vehicle body 18 to lock. The locking mechanism 31 consists of a coupling head 31a with a rectangular end face, the coupling head 31a can optionally be inserted into a locking bore 31b of the vehicle body. The coupling head 31a is connected to an adjusting lever 31c, which both is rotatable and movable in the longitudinal direction. The shape of the locking hole 31b is rectangular. It is slightly larger than the rectangular end of the locking head 31 · Once the locking head 31a is inserted into the locking bore 31b and rotated by a certain angle, e.g. 90 °, that is The cargo vehicle 1 is locked to the vehicle body 18. In this context, it should be emphasized that that when the fitting bolt 29 is inserted into the fitting bore 30, the locking head 31a is brought into one position in which it can be inserted into the locking bore 31b to effect locking.

The with the cargo vehicle according to the above Construction possible operation is explained in detail below.

First of all, it is assumed that a battery 44 standing on the vehicle body 18 is

030050/0666

tool 1 is to be reloaded according to the invention. To do this, the cargo vehicle is attached to one side of the vehicle body 18 rolled up. Then the oil hydraulic The cylinder is actuated until the carrier 6 has reached an altitude in which it can take over the battery 44. Before or at the same time the fitting bolt 29 is aligned with the fitting bore 50 and inserted into it, wherein the handle 31 is also operated to insert the locking head 31a into the locking bore 31 and to lock him in there. Then one of the two hooks 27 is connected to the hook 26, which is on a Side surface of the battery 44 is located. As soon as the Drive lever 28a is operated, the drive device 28 is moved so that the rotatable shaft 23a and the drive wheel 23 causes the chain 25 to revolve. The load hook 27 pulls the battery onto the low-friction Plates 19 and 5 or the roller tables 20 and 8 until the battery 44 rests against the stops 7 and in their end position on the truck 1 is.

Conversely, a battery 44- from the cargo vehicle 1 reloading onto the vehicle body 18, the cargo vehicle 1 is in turn aligned with the vehicle body 18 and thus locked. Then the drive device is operated in the reverse direction, so that the Drive wheel 23 rotates in the opposite direction and, via hook 27, battery 44 is placed on the vehicle body 18 is pushed until it is in the desired end position.

To lighten load. Otherwise is in the embodiment the Mg. 9 and 10 stop 7 is no longer provided and in addition, the drive device for the chain can only be moved in one direction. Of course it's possible, to provide a separate carrier 6 also in this embodiment of the goods vehicle 1, that of vertically adjustable Actuating means is raised. The non-reversible drive mechanism 43 engages the drive wheel 23 at. For this purpose, the drive wheel 23 is integrally connected to a rotatable shaft 23a which sits a drive pinion 32 rotatably relative to the shaft 23a - A ratchet wheel 33 is adjacent on the shaft 23a attached by the drive pinion 32. By actuating a cylinder 34, a rack 35 can be back and forth move forward, which engages in the drive pinion 32. A pawl 36 is pivotally attached to a side surface of the drive pinion 32 and is supported by a leaf spring 37 of the drive pinion 32 is loaded into engagement with the ratchet wheel 33. A guide 38 for the rack 35 is attached to the goods vehicle 1 or possibly the carrier 6 and supports a pivotable pawl 39 · A spring 40 on the cargo vehicle I loads the The pawl 39 engages the ratchet wheel 33. As soon as the cylinder 34 extends its piston rod forward, the rack 35 also moves forward with the rotation of the drive pinion 32. In this case takes the pawl 36 of the drive pinion 32 with the ratchet wheel 33, so that the shaft 23a with the ratchet wheel 33 turns. This results in a movement of the drive wheel 23 and the chain 25. The pawl 39 allows the ratchet wheel 33 a rotation in this direction, while locking its rotation in the opposite direction. The movement of the piston rod of the cylinder 34 becomes automatic conversely, when one end of the piston rod 35 with a Limit switches 41, 42 cooperate, which are arranged at the ends of the stroke of the rack 35. When going back

030050/0666

pulling the rack 55 turns the drive pinion 32, but the pawl 36 jumps over the ratchet wheel, so that the shaft 25 does not rotate. The pawl 39 secures the shaft 23a in this case a reverse rotation. It follows that the chain 25 can only be moved in one direction. Ever after whether the battery 44 from the truck 1 on the vehicle body 18 is charged or reloaded by it is to be, the position of the truck 1 is changed by 180 ° relative to the vehicle body 18.

As explained above with reference to the invention, conveying devices for moving are on a freight vehicle a heavy load arranged to work with or without a carrier, so that the work and the individual loading steps can be simplified or reduced. An expensive and complex mechanism for loading or reloading heavy loads, such as a crane or the like, can can be saved. Another advantage of the present invention is that the auxiliary worker is the person to be reloaded The load does not have to come into direct contact with the fingers, which significantly increases work safety. In addition, if the truck is using a non-reversible drive such as that shown in Figures 9 and 10, the operation can be carried out safely even if the plane in which the heavy loads must be moved is inclined at an angle lies.

Although the invention has been explained with particular reference to the illustrated embodiments, these embodiments only represent possibilities from a large number of possibilities. Changes in Details of the construction and the combinations and the arrangement of individual components can be made without that the scope of the invention would thereby go.
