DOMCS - Dynamic Optimized Matching Control System

Positive flow controlled hydraulic system

Main pump displacement is directly proportional to the signal pressure from the joystick.
The controller determines the flow demand and variation trend of the actuator and regulates the flow in the system.
 
Electronic control module achieves the best energy efficiency.
Control is integrated with sensors to conduct monitoring of all systems and auto adjust. 
 
Boom priority operation
 
Boom priority from swing rotation controlled by DOMCS improves operational efficiency.
 
Automatic idling system
