Design and Application of Automation System for Bridge Grab Crane
In response to the shortcomings of traditional bridge type grab cranes in use,DCS control system and WCS linear absolute value encoder were introduced to automate the grab crane,achieving unmanned operation on site,reducing equipment failure rate and labor intensity of workers.The introduction of automatic control systems has made the transition between each stage of the entire process smooth,with higher control accuracy and faster operation speed,greatly improving the work efficiency of grab cranes.The design has been applied in the grab bucket transformation of coal gasification plant of Shanxi China Coal Pingshuo Energy Chemical Co.,Ltd.,and the effect is remarkable.
