Abstract

To meet the requirements of railway crane control,a crane performance is analyzed and a control system based on programmable logic controller is presented.By utilizing the analysis of programmable logic controller I/O the load signal and act speed commends are input to controller CPU,and speed control signals are output to electro-hydraulic proportional amplifier from the CPU.This control system is applied to a NS1251 railway crane,and results indicate that the system improves the efficiency,reduces the assembling and maintenance time of the railway crane,and its general performances are much higher than that of the full scale hydraulic control railway crane.
