HYDRAULIC SYSTEM

All the main hydraulic components (pumps, valve, motor, connector) are from well-known international brands such as Bosch-Rexroth, Brevenni, which ensure the entire system more stable, reliable, high-efficient and energy-saving.

CAT hydraulic system acts as the main circuit that takes the complete power control, distributive power control and negative flow control. Auxiliary hydraulic circuit is based on the most advanced and energy-saving load-sensing technique among international heavy-duty machine and equipment. Therefore, it realizes optimum pump power output matched with the loads of moving actuators.

The compound action of main winch and rotary drive head is controlled bu double circuits. it ensures independent operation  for their compound movements. So it improves the mechine capability dealing with complex case.
