<p>Hand winch comprising a winding roll (5) for receiving a flexible elongated member, a manually operated shaft (15), acting on the winding roll, and a friction brake (17) including a brake disc (23) and a gear element (20) engaging with the winding roll and mounted on the shaft such that said gear element can move between a release position and a brake position in which the gear element enters into frictional contact with said brake disc, thus generating a braking torque opposite to a direction of winding off the flexible elongated member, for braking the winding roll, whereby a friction means (50) positioned between the shaft and the gear element and generating a frictional resistance between the shaft and the gear element such that, if a driving force acting on the gear element does not overcome the frictional resistance established by the friction means, the gear element drives the shaft via said friction means and that, if said driving force between the shaft and the gear element overcomes said increased frictional resistance, a relative movement of the gear element with respect to the shaft occurs.</p> |
