ABSTRACT:
An overload protection device (1) with a primary section (4) for the coupling of the overload protection device (1) with a drive device (2) and with a secondary section (6) for coupling of the overload protection device (1) with an operating section (7). The primary section (4) and the secondary section (6) can be turned around a rotation axis (8), with respect to one another, around a rotation angle phi. A spring element (5), which is interposed between the primary section (4) and the secondary section (6) is formed in such a way that the spring element (5) counteracts a rotation of the primary and secondary sections (4, 6). The invention is characterized by a spring element (5) that extends concentrically around the rotation axis (8) in an angular range of at least 180°.
