摘要

Gripping device (26) for raising and lowering a submersible unit such as a submersible motor-driven pump or stirring device comprises a hook-like second coupling element (46) guided on a guide device and which can be coupled to/decoupled from an eyelet-like first coupling element on the submersible unit. The second coupling element has a hook element (44) pivotably suspended on a first pivot axle (40) and provided with a release element (52) spring-mounted about a second pivot axle (56) between a mechanically tensioned first position and a second position releasing the first coupling element by mechanical release. Preferred Features: The hook element has a shaft (42) hanging downward from a hook holder (30) and freely pivoting about the first pivot axle. A hook fluke (60) protruding from the under side of the shaft is assigned to the spring-mounted release element.
