Considering that the container spreader of rail container crane often sends fault alarm,a fault diagnosis plan of the spreader based on the system analysis of the whole machine is put forward by combining the factors such as electrical control logic,electrical alarm control and signal transmission.This plan is based on the combination of mechanical and electrical methods,from the data analysis of the fault alarm display system of the whole machine to the demonstration of signal transmission process,and simulates the driver's opening and closing conditions.A large number of simulation tests were carried out on the spreader by using the simulation control box,and optimization measures were given according to the test results.The on-site fault diagnosis test results show that the fault causes can be found in a more efficient and comprehensive manner by adopting this plan,which meets the fault detection requirements of container loading and unloading yards.
