Abstract
Disclosed is a method and apparatus to provide a pendant or operator interface for controlling a variable velocity cable lift. In particular, the present invention is intended for use with an electrically-actuated cable lift, and simulating the performance of a pneumatic or similar lift mechanism. The invention is directed to the control handle or interface for such a system, which employs a variable displacement transducer as a substitute for a force-sensing handle.
