The hydraulic system of this machine includes motors, oil pumps, control valve manifolds, oil tanks and other systems and various connecting pipelines. The pipelines of the hydraulic system are all connected by high-pressure flanges to avoid leakage of hydraulic oil. All oil pipes are pickled before welding, and then after welding slag, deburring and secondary pickling to ensure the cleanliness of the hydraulic pipeline.
