In the actual operation process of crane truck, wheel flange and track side will extrude each other, resulting in friction, which is the gnawing phenomenon. During the operation of crane trucks, biting often occurs. The crane mainly uses displacement sensor to measure the deflection of the track. The main control signal is the deflection. The

Programmable controller is also called PLC. PLC is an electronic device specially designed for digital operation in industrial environment. It uses programmable memory to store instructions to perform logical operations, sequential operations, timing, counting and arithmetic operations within it, and to control various types of machinery or production processes through digital or analog inputs and
