= Abstract The present invention relates to a system for changing work tools on a loading crane comprising a first coupling member (1) on the work tool side or the loading crane side with a receiving opening (4) and a second coupling member (2) on the loading crane side or the work tool side with a guide member (21) [sic; (22)] extending along a longitudinal axis (20), which guide member can be made to engage in the receiving opening (4) of the first coupling member (1) by moving the first coupling member (1) and the second coupling member (2) toward each other in the direction of the longitudinal axis (20), with the first coupling member (1) comprising a support surface (11) for axially abutting the second coupling member (2) and with the second coupling member (2) comprising a bearing surface (27) complementary to the support surface (11) and at least one locking element (32) which can be moved by means of a drive (30, 31, 32) [sic] at right angles relative to the longitudinal axis (20) of the second coupling member (2) between a disengaged position and a retaining position. According to the invention, the locking element (32) has a clamping surface (34) for frictionally abutting the first coupling member (1) and the first coupling member (1) has an abutment surface (13) complementary to the clamping surface (34) for zero-play axial clamping of the first coupling member (1) and the second coupling member (2). ..
