Abstract
The invention concerns a load balancing device consisting of a planetary or trochoidal mechanical differential speed reducer, arranged on a winch comprising two drums and enabling to balance the torque exerted on the drums. Thus, if a cable is improperly wound on one of th drums, the balancing device enables the tensile load exerted on each wire to remain identical. Such a device is particularly efficient to ensure security for a working platform operating on a building facade.
