Abstract

The invention relates to a gripper for raising and lowering loads and having the following configuration:—it comprises a coupling part and a connecting part,—the connecting part is guided on the coupling part for movement along a movement axis between a first end position and a second end position, 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 are present on the coupling part and can be moved between a gripping position, in which they use a rear-engagement surface to engage behind a mating element of the load, and a release position, in which they release the mating element,—the connecting part is connected to the at least two catch elements via at least one gear mechanism.
