ABSTRACT:
A vehicle lift (10) for transporting a wheelchair passenger between a ground-level position adjacent the vehicle (12) to a position adjacent to and substantially coplanar with the vehicle floor (14) includes a contact sensor (16) for detecting when the lift platform contacts a curb or other object. A carriage assembly (20) includes a pair of slides (34) that ride on a pair of rails (36). As the platform is lowered, the relative position of the slides (34) and the rails (36) changes. The sensor (16) detects a relative position of one of the slides (34) and the corresponding rail (36). When the sensor (16) detects a relative position of the slide (34) and the rail (36) indicating that the platform has contacted a curb or other object, the sensor (16) generates a control signal. A lift controller (60) stops lowering of the platform in response to the control signal from the sensor (16).
