【正文】 全鉗 Safety Linkage under outer platform Linkage in the crosshead Platform Wood floor Load weighing sensor Floor brick Welded frame Sill support Rubber pad Toe guard Sill Platform Plank Platform Rubber pad Toe guard Sill support Load weighing Sill Load Cell LOAD CELL DEFINITION Load cell is a safety device that sends out warnings and makes car not moving with door opened when load exceeds rated duty. Besides Overload function, it can also (1) Weigh the load, send signals to controller, which then can give machine pretorque to start car smoothly. 1. Definition: What is load cell? 2.
