A gripper device () is provided for mounting rubber elastic rings () on the inner wall () of a workpiece opening and/or on the exterior of a workpiece. The device includes a basic housing (), forming jaws () that are displaced in relation to the basic housing () and bearing jaws (). To displace the plate element together with the jaws that are located on the element in an axial direction, the element is provided with a piston () which engages in a piston cylinder () in the basic housing. The displacement of the jaws that are located on the plate element () is mechanically coupled by a common actuator () and the actuator () is driven by an actuator piston () that is located in the piston ().

The invention relates to an overload protection device () comprising a housing () which is designed to be fixed to a manipulation device. The overload protection device comprises a tool holder () for fixing a tool that is attached to the housing in a displaceable manner, a pre-tensioning unit () 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 () 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 () and at least one electrically conducting contact element () that can be brought into electrical contact with the switching surface, the switching surface () and the contact element () being provided on an opposing surface section () of the tool holder and the housing. The contact element () is configured as a sealing element, which seals off at least sections of the pressure piston from the switching surface ().

A parallel gripper includes a housing and two adjustable gripper base jaws which are displacably guided in a jaw guiding recess. The base jaws are moved relative to one another by a wedge hook gearing that is adjusted by a piston guided in the housing. The jaw guiding recess is provided with complementary configured guiding grooves. The ratio of the wall thickness of the housing between the base of the guiding grooves and the outside of the housing to the width of the housing measured vertically in relation to the direction of displacement of the base jaws is at least 0.2. The ratio of the width of inclined traction of the wedge hook gearing to the outside width of the base jaws is at least 0.4.
