Abstract
Traditional bridge crane control system lacks of reliability and efficiency.Hence,a new PLC and variable frequency drive technique are used to the crane on the vehicle body phosphating line of Zhengzhou Yutong Bus Co.,Ltd.This control system can automatically drives the crane to the desired position accurately.The new control and driving system improves the line performance and the operation safety.It also reduces the system failures,and can decreases the power consumption obviously at the same time.
