The receiving device 16 is aligned as vertically parallel to the housing 12 Retaining ring formed and is penetrated for example by a crane hook.

The lifting arms 14a, 14b define a load receiving space 18 with the housing 12 connecting them. The load receiving space 18 has a substantially rectangular cross-sectional shape and is open to one side, down here. Via this opening, a load-receiving means, such as a rope, a chain or a fixedly attached to the load eyelet, are introduced into the load receiving space 18. In the load receiving space 18, a component 20 can be inserted, which has a locking part 24 for closing the open side of the load receiving space 18. The locking part 24 is formed like a bar and connected to a control part 26 via a likewise beam-like web portion 28. The locking part 24, the control part 26 and the web part 28 form the movable member 20 of the lifting device 10. In the jargon, the component 20 is sometimes referred to as a "pawl".

In the 1a and 1b the component 20, which is movable about a pivot axis S, is pivoted into the load receiving space 18 and delimits, with the lifting arm 14a shown on the right, a receiving space 22 for the load-carrying means not shown in the figures. The receiving space 22 is a partial space of the load receiving space 18 and also has a substantially rectangular cross-sectional shape. According to a translational movement T1, in the representation of Fig. 1a from top to bottom, the locking part 24 has been brought into the locked position shown and there in abutment with abutments 30a, 30b. The abutments 30a, 30b are each arranged in the end region of the lifting arms 14a, 14b assigned to the open side of the load receiving space 18 and are designed as a cylindrical web (abutment 30b) or as a wedge-shaped receptacle (abutment 30a).

About a translational return movement T2, in the representation of Fig. 1b from bottom to top, the locking member 24 is in the released position and out of engagement with the abutments 30a, 30b brought. In Fig. 1b are the counter to the abutments 30a, 30b formed locking lugs 32a, 32b of the locking member 24 clearly visible. The one latching nose 32 a is at the in the Fig. 1a to 1d shown on the right, free end of the locking part 24 is formed and engages in the wedge-shaped abutment 30a on the lifting arm 14a. At the opposite end of the locking part as a kind of extension, the locking lug 32b is formed to rest against and on the cylindrical abutment 30b on the lifting arm 14b.
