main control system, LMI system, auxiliary system and safety
monitoring system. CAN BUS is used for data communication
between controller, monitor and the engine;
▪▪Monitor: the working parameters and status are shown on the
monitor, such as the engine speed, fuel volume, engine oil
pressure, servo pressure, wind speed, engine working hours,
lifting conditions and boom angle.

Hydraulic System
▪▪Main pumps: open variable displacement piston pumps of
large displacement are adopted to provide oil supply for main
actuators of main machine;
