Abstract

A quick coupling is proposed for attachments (2) to be displaced on the lifting frame (1) of a carrier vehicle, the lifting frame (1) being formed from two lifting arms (3) running essentially parallel to one another. The lifting arms (3) are mounted at one end on the carrier vehicle and the other ends (4) of the lifting arms (3) accommodate between them a hollow body designed as a crosspiece (5). A drawbar link pair (6) is mounted on the crosspiece (5) in an articulated manner. The free end of the drawbar link pair (6) can be connected to elements of the respective attachment (2) and in the area of its extension interacts with at least one drawbar mounted in an articulated manner. The drawbar in turn can be connected to further components provided in the area of the lifting frame (1), and the locking device for locking the lifting frame to the respective attachment is provided inside the hollow body. <IMAGE>
