Abstract: Rail-mounted lift systems, systems comprising the same, and kits of parts for retrofitting rail-mounted lift systems are disclosed. A lift system includes a rail having a carriage support channel formed therein, a carriage slidably disposed in the carriage support channel for relative movement to the rail, a lift unit coupled to the carriage, the lift unit having a motor that extends and retracts a lifting strap, and a locating system having a first component and a second component separate from the first component. One of the first and second components is a transmitter providing a code that corresponds to a predetermined location and the other is a receiver detecting the code when the first and second components are moved in proximity to one another due to movement of the carriage along the rail.

Abstract: A method of determining a lifting event of a person lifting apparatus is provided. The method includes receiving one or more of (i) current load information from a current measuring device that is indicative of current drawn by an actuator operatively connected to a lifting strap of the person lifting apparatus; (ii) strap position information from a position sensor that is indicative of a paid out length of the lifting strap of the person lifting apparatus; and (iii) weight information from a weight sensor that is indicative of a load supported by the lifting strap of the person lifting apparatus. A computing device comprising a processor using logic is used to identify at least one of a raising event, a repositioning event and a lowering event based on the one or more of the current load information, strap position information and weight information.
