Abstract

See full text

A system for changing work tools on a loading crane includes a first coupling member on the work tool side or the loading crane side with a receiving opening and a second coupling member on the loading crane side or the work tool side with a guide member extending along a longitudinal axis. The guide member engages in the receiving opening by moving the first and second coupling members toward each other. The first coupling member comprises a support surface for axially abutting the second coupling member and the second coupling member comprises a bearing surface complementary to the support surface and a locking element which is movable by a drive between disengaged and engaged positions. The locking element has a clamping surface for frictionally abutting the first coupling member and the first coupling member has an abutment surface complementary to the clamping surface for zero-play axial clamping of the first and second coupling members.
