Abstract: The invention relates to a stop module for the swiveling motion of a rotation body (14) that is swivelably received in a housing (10). The stop module comprises a catch (26) following the trajectory of the swiveling motion on the end of the rotation body and a stop (48) comprising a damping element for delimiting the motion of the catch (26). At least one intermediate element (56) is provided between the catch (26) and the stop (48) and is supported, when impinged upon by the catch (26), on the housing (10) and on the stop (48).

Abstract: The invention relates to an overload protection device (1) comprising a housing (2) which is designed to be fixed to a manipulation device. The overload protection device comprises a tool holder (3) for fixing a tool that is attached to the housing in a displaceable manner, a pre-tensioning unit (4) for generating a pre-tensioning force between the housing and the tool holder, the pre-tensioning unit being configured as a piston assembly with a pressure piston which can be loaded by a medium and with a switching unit (5) that operates by means of relative displacement between the housing and the tool holder. The switching unit has a least one electrically conducting switching surface (6) and at least one electrically conducting contact element (7) that can be brought into electrical contact with the switching surface, the switching surface (6) and the contact element (7) being provided on an opposing surface section (8) of the tool holder and the housing.

Abstract: The invention relates to a rotating or pivoting device (110) comprising a housing (12), at least one working piston (14) which is mounted in the housing and subjected to a pressure medium, and a pivoting part (20) which is rotatably mounted in the housing and is rotatably driven by the working piston by means of a rotating coupling mechanism, the working piston being mounted in the housing in such a way that it can be displaced in a housing-side cylinder, The inventive rotating or pivoting device also comprises an abutment part (114) that limits the stroke of the working cylinder in at least two positions and can be locked at least in its axially inner intermediate position.

Abstract: The invention relates to a rotary or pivoting device (10) comprising a housing (12), at least one working piston (14) that is located in the housing and can be impinged by hydraulic fluid and a pivoting part (20), which is rotatably driven by the working piston via a rotary coupling (18) and is rotatably mounted in the housing. According to the invention, the working piston is displaceably mounted in at least one cylindrical tube (22).
