ELECTRONIC LIFT INTERFACE USING LINEAR VARIABLE DIFFERENTIAL TRANSDUCERS

摘要

Disclosed is a method and apparatus to provide a pendant or operator interface (12) for controlling a variable velocity cable lift (10). In particular, the present invention is intended for use with an electrically-actuated cable lift (10), and simulating the performance of a pneumatic or similar lift mechanism. The invention is directed to the control handle or interface (12) for such a system, which employs a variable displacement transducer (124) as a substitute for a force-sensing handle.
