Lift systems with continuous in-rail charging

摘要

Abstract Rail-mounted lift systems are disclosed. In one embodiment, the lift system includes a rail having at 5 least one conductor positioned on an upper interior surface of the rail. A carriage may be slidably disposed in the rail for relative movement to the rail. The carriage generally includes a carriage body, at least one pair of support wheels rotatably coupled to the carriage 10 body and slidably engaged with the rail, and a conductor truck comprising at least one conductive roller rotatably attached to the conductor truck. The conductor truck may be mounted to the carriage body with a biasing member upwardly biasing the conductive roller into rolling 15 engagement with the at least one conductor. A lift unit may be coupled to the carriage body and includes a motor paying out and taking up a lifting strap. The lift unit is electrically coupled to the at least one conductive roller. 2?20332_1 (GHMatters) P87479.AU 27/06/11 o00
