The design key of the trolley hydraulic drive mechanism of the hydropower station two-way gantry crane is to keep driving the trolley to run synchronously on both sides of the hydraulic cylinder,and take measures to prevent the piston rod produce deflection and bending and twisting deformation.Hydraulic pipeline symmetrical layout,reduce the pipeline influence to the cylinders synchronization.Hydraulic systems use flow speed control valve correction circuit by-pass oil drainsynchronization control.Joint bearing and sliding bearing group and resist to deflection bracket,to achieve the hydraulic cylinder to the outside generated torsion,bending and twisting of the adaptive.Engineering practice proves that: the trolley hydraulic drive mechanism run steady,regulate synchronous accurate,no skew traveling phenomenon and meeting the actual working condition needs.
