Features:
HD160G hydraulic drive bulldozers is a kind of crawler dozer with160 horsepower, which is hydraulic direct driving, semi-rigid suspended and hydraulic controlled. It adopts Shangchai C6121 diesel engine manufactured under Caterpillar license, which features big torque reserve coefficient and capacity against over-load. Hydro-mechanical torque converter is adopted, whose power is divided outside. It features wide high efficiency range. Steering and braking can be controlled by the same control rod. Braking system employs the convenient and labor-saving hydraulic boosting structure. The final drive gear has such features as large displacement coefficient value. This design improves the carrying capacity and lengthens the service time. The final drive also adopts the structure of free adjustable bearing clearance, which is convenient for service. The balance bar is designed with free lubricating structure, which helps to decrease service cost.
