Patent

CA 2737727

A fall protection system comprising a line wound onto a rotatable pulley having a centrifugal clutch which activates a gearbox which in turn drives an input shaft of a hydraulic actuator whereby the hydraulic actuator controls the rate of rotation of the pulley, and a secondary brake which slows the rotational speed of the pulley should it exceed a predetermined speed, whereby in use, the line is attached to a user to restrain a fall and then the system facilitates unwinding of the line at a controlled speed to effect descent.

Linvention concerne un système de protection antichute comprenant un câble enroulé autour dune poulie rotative dotée dun embrayage centrifuge qui actionne un boîtier dengrenage, qui à son tour entraîne un arbre dentrée dactionneur hydraulique. Ledit actionneur hydraulique commande la vitesse de rotation de la poulie, et un frein secondaire ralentit la vitesse de rotation de la poulie même lorsquelle dépasse une vitesse prédéterminée. Lorsquon lutilise, le câble est fixé à un utilisateur pour lempêcher de chuter, puis le système facilite de déroulement du câble à une vitesse maîtrisée pour effectuer une descente.
