ABSTRACT:
The descender comprises a first flange for support of a pulley and a pad, and an auxiliary braking lever mounted with limited pivoting near the pulley between an inactive unlocking position for a first winding direction of the rope in the passage space, and an active locking position in which a jamming surface of the lever presses the rope against the pulley. Pivoting of the lever to the active position takes place automatically in case of incorrect winding of the rope according to a second direction opposite to the first direction, and in the presence of a tension on the rope when the descender is on load.
