摘　　要：双起升岸边集装箱起重机上架分离油缸是控制海侧、陆侧吊具相对位置和姿态的重要部件,分离油缸伸缩同步是其高效作业的关键。针对原机分离油缸同步精度不足问题,从节流阀控制、集装箱积载等方面分析原因,给出一种液压同步马达和旁路电磁阀协同控制的解决方案。实施改造后,油缸同步精度明显提高。The separation cylinder of the double hoisting quayside container crane is an important component to control the relative position and attitude of the lifting appliances at sea and land sides.And the telescopic synchronization of the separation cylinder is the key to its efficient operation.In view of the lack of synchronization accuracy of the original separation cylinder,the causes of throttle valve control,container stowage and other aspects are analyzed,and a solution for the coordinated control of hydraulic synchronous motor and bypass solenoid valve is given.After the reform,the synchronization accuracy of the oil cylinder is obviously improved.
