The present invention relates to a device for changing work tools on a loading crane, comprising 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, which guide member can be made to engage in the receiving opening by moving the first coupling member and the second coupling member toward each other in the direction of the longitudinal axis, with the first coupling member comprising a support surface for axially abutting the second coupling member and with the second coupling member comprising a bearing surface corresponding to the support surface, wherein at least one locking element can be moved by means of a driver at right angles relative to the longitudinal axis of the second coupling member between a disengaged position and a retaining position. According to the invention, the locking element has a clamping surface for frictionally abutting the first coupling member and the first coupling member has an abutment surface corresponding to the clamping surface for zero-play axial clamping of the first coupling member and the second coupling member.

    本发明涉及一种用于更换装载起重机上的工作器具的装置,包括工作器具侧或装载起重机侧的第一联接部件及装载起重机侧或工作器具侧的第二联接部件,第一联接部件有接纳开口,第二联接部件有沿纵轴线延伸且由于第一联接部件和第二联接部件运动到一起可沿纵轴线的方向与接纳开口接合的引导部件,第一联接部件包括与第二联接部件轴向贴靠的支撑面,第二联接部件包括与支撑面对应的支承面,至少一个借助于驱动器能横向于第二联接部件的纵轴线在释放位置和保持位置之间移动的锁定元件。根据本发明,锁定元件有用于与第一联接部件力锁合地贴靠的夹紧面,第一联接部件包括与夹紧面对应的贴靠面,以用于无间隙地轴向夹紧第一联接部件和第二联接部件。
