Abstract
The invention relates to a self-locking descender wherein the pulley in the form of a cam is equipped with a drive finger cooperating with a mechanism having a transmission rod movable between an active engagement position with the finger to establish a unidirectional mechanical link between the handle and cam when the handle is actuated to an intermediate unlocking position in the course of the descending movement, and an inactive escape position to break said mechanical link after the intermediate position of the handle has been passed, causing disengagement of the pulley and automatic return of the cam to the locking position due to the action of the tension of the rope. The locking effect of the rope is thus preserved after disengagement, without maintaining a force on the handle.
