Abstract (en)
[origin: WO0138217A1] The invention concerns a load balancing device (4, 5) consisting of a planetary or trochoidal mechanical differential speed reducer, arranged on a winch (3) comprising two drums (32, 33, 36, 37) and enabling to balance the torque exerted on the drums. Thus, if a cable (210, 211, 220, 221) is improperly wound on one of the drums the balancing device enables the tensile load exerted on each wire to remain identical. Such a device is particular efficient to ensure security for a working platform (10) operating on a building façade (10).
