The lifting gear comprises two motors (1, 1') that are connected to a transmission (6) via respective drive shafts (2, 2'), couplings (3, 3'), with fitted brake disks (4, 4') or brake drums, brakes (14, 14') and transmission input shafts (5, 5'). The transmission (6) drives cable drums (9, 9') via transmission output shafts (7, 7') and couplings (8, 8'). Said cable drums have a cable pull (12, 12') and fitted brake disks (10, 10') or brake drums and safety brakes (11, 11'). The inventive lifting gear is characterized by comprising, in the drive shafts (2, 2'), devices (13, 13') that completely or partially disconnect the motors (1, 1') from the transmission (6) when an excess load exceeds the predetermined load. They are monitored on both sides of the devices (13, 13') and the brakes (14, 14') and/or safety brakes (11, 11') are activated in the event of disconnection.

Le dispositif de levage selon l'invention présente deux moteurs (1, 1'), qui sont raccordés chacun à une transmission (6) par l'intermédiaire d'arbres d'entraînement (2, 2'), d'accouplements (3, 3') sur lesquels sont montés des disques de frein (4, 4') ou des tambours de frein, des freins (14, 14'), et par l'intermédiaire d'arbres d'entrée de transmission (5, 5'). La transmission (6) frotte sur des tambours à câbles (9, 9') par l'intermédiaire d'arbres de sortie de transmission (7, 7') et d'accouplements (8, 8'). Les tambours à câble présentent un câble (12, 12') ainsi que des disques de frein (10, 10') ou des tambours de frein et des freins de sécurité (11, 11'). Selon l'invention, le dispositif de levage présente, dans les arbres d'entraînement (2, 2'), des dispositifs (13, 13') qui séparent totalement ou partiellement la liaison entre les moteurs (1, 1') et la transmission (6) en présence d'une surcharge dépassant une charge prévue. Une surveillance est exercée des deux côtés des dispositifs (13, 13') et, lors d'une séparation, les freins (14, 14') et/ou les freins de sécurité (11, 11') sont activés.
