Abstract
A scissors lift includes a scissors arm assembly secured at one end to a base and coupled with a lift mechanism that expands and contracts the scissors arm assembly. A platform is supported at an opposite end of the scissors arm assembly via a plurality of load sensing pins that detect a vertical load on the platform. An interface module receives signals from the load sensing pins and communicates with the lift mechanism, wherein the interface module controls operation of lift functions and the lift mechanism according to the signals from the load sensing pins. Preferably, the load sensing pins are sized substantially the same as the conventional pins they replace. As a consequence, no redesign or additional structures are necessary to install the load sensing system and provide a safe operation of the scissors lift machine.
