    • The invention relates to a gripper for raising and lowering loads and having the following configuration: - it comprises a coupling part (3) and a connecting part (4), - the connecting part is guided on the coupling part for movement along a movement axis (5) between a first end position (E1) and a second end position (E2), wherein those ends of the aforementioned parts which are oriented away from one another are further apart from one another in the first end position than in the second end position, - at least two catch elements (7) are present on the coupling part (3) and can be moved between a gripping position (G), in which they use a rear-engagement surface (8) to engage behind a mating element (9) of the load (2), and a release position (F), in which they release the mating element, - the connecting part (3) is connected to the at least two catch elements (7) via at least one gear mechanism (10) such that, in the first end position (E1), the catch elements are located in their gripping position (G) and, in the second end position (E2), the catch elements are located in their release position (F), - the at least two catch elements (7) are spaced apart from one another in the circumferential direction of an imaginary circle (13) which concentrically comprises a centre longitudinal axis (6) of the gripper (1), said axis running parallel to the movement axis (5), - the catch elements (7) are spaced apart from the centre longitudinal axis (5) by a greater distance (14) in the gripping position (G) than in the release position (F).
    • 本发明涉及一种用于提升和降低负载的夹具,该夹具具有以下结构: - 它包括联接部分(3)和连接部分(4), - 连接部分在联接部分上被引导用于沿着移动轴线 (E1)和第二端部位置(E2)之间的第一端部位置(5),其中在第一端部位置中彼此远离的上述部件的那些端部比在第二端部中彼此进一步分开 位置上, - 至少两个止动元件(7)存在于联接部件(3)上并且可以在抓持位置(G)之间移动,在抓持位置(G)中,它们使用后接合表面(8) 其特征在于,所述连接部件(3)通过至少一个齿轮(7)与所述至少两个止挡元件(7)连接,所述至少两个止挡元件(7) 机构(10),使得在第一端部位置(E1)中,捕捉元件位于其中 在所述第二端部位置(E2)中,所述止动元件位于其释放位置(F)中, - 所述至少两个止动元件(7)沿着所述抓持位置(G)的圆周方向彼此间隔开 (1)的中心纵向轴线(6)同心地构成的假想圆(13),所述轴线平行于所述运动轴线(5)延伸,所述卡扣元件(7)与所述中心纵向轴线 (5)在夹持位置(G)上比在释放位置(F)中更大的距离(14)。
