The engine is equipped with advanced modular common rail fuel system (MSRS) to meet the Euro-IIIA/China-III emission regulation.
Cyclone intake system with double prefilter effectively prevents the earlier malfunctions of engine.
The hydraulic torque converter with locking function is applied to output the torque along with the variation of load, featuring powerful load adaptability (Hydraulic drive at low speed and mechanical drive at high speed) and high fuel economy (Fuel-saving by 10%~15%).
The normally closed brake plays the parking brake function to effectively prevent the machine gliding on slopes and realize high safety.
Not relying on the main frame, the final drive adopts modular design and can be assembled independently to ease the repairs.
