ABSTRACT:
A positioning appliance for accurately positioning a container suspended on crane cables with respect to a chassis on which the container is being placed comprises two slide chutes (30, 31) which are each pivotably suspended on a carriage (32 and 33 respectively). The carriages can be moved along a rail (34). In order to make the appliance suitable for any type of chassis whatsoever, including a chassis suitable for the public highway, the slide chutes must not come into contact with the chassis. The appliance according to the invention makes this possible in that a spacer (37) which can be moved in the direction of movement of the carriages is disposed between the carriages. Each carriage is provided with a stopping device (38 and 39 respectively) which can be brought into engagement with the spacer by moving said carriages. Hydraulic or pneumatic cylinders (35, 36) for moving both carriages are so coordinated in the event of contact between the two stopping devices and the spacer that the carriages, the stopping devices and the spacer are able to move as one unit.
