Chinese bulldozer

Closed system hydraulic oil in the hydraulic system in a closed loop, compact, Chinese bulldozer high transmission efficiency, and the air is not easy to enter, drive smooth and good; but the closed system structure is complex, poor thermal performance. Construction machinery working device actuator control system to intermittent work based on the transmission efficiency is not critical, it is generally the choice of an open system.
Hydraulic driven system from the power components, actuators, control components and auxiliary equipment and piping components.
