Device for detachably fixing interchangeable bodies to flat-bed lorries

摘要

The device comprises a holding unit on the vehicle side and having a holding bracket (12) with opening (13) which is to be brought opposite the opening (9) in the holding console (8). A holding wedge (11) for insertion through the console opening and bracket opening has at least one of its opposing pressure faces running inclined to the insert direction so that in the fixing state one pressure face of the wedge is in constant pressure contact with the console opening and the opposite pressure face is in constant pressure contact with the bracket opening wall. The holding wedge can have a plate or conical shape and is moved hydraulically, pneumatically or electromechanically between its locking and release position. The holding wedge can be constantly pretensioned in the insert direction in the fixing state. A guide element for the wedge protrudes in the direction of the lift cylinder (17) over the console.
