摘要:
A lift apparatus has a frame with open sides and a web assembly slidably retained along the sides which extends from one end of the frame to the other. While the web assembly is retracted, the frame moves to pass around a mobility-impaired individual and rest against the surface supporting the individual. The web assembly is then extended to move underneath or behind the individual, providing lifting support. The frame is configurable for orientations ranging continuously between horizontal and upright sitting. The web assembly has an upper web contacting the individual, a lower web contacting the support surface, a strength layer carrying the individuals weight, and a roller nose bar assembly which is pulled to extend the web assembly. A hand-held power tool can drive the web assembly, adjustment of inclinations of the back and leg sections of the frame, and vertical motion of the lift arm.
