G30 Steel cut off the hydraulic system design, the principle is the use of hydraulic technology, steel cut in the saw blade to achieve fast forward, working forward, rewind and steel pipe clamp, pine folders and other processes, the entire cutting process automation. Hydraulic system design is mainly based on the hydraulic system of the machine, the hydraulic system than other systems have many advantages, and hydraulic technology to today
