Product Description

Products Description

* The high reliability power shift transmission and the planetary gear final drive feature high power transmission efficiency and high durability and productivity.

* The cooling system fan speed is automatically regulated depending on the engine coolant temperature to shorten the time required for the water and oil temperatures to reach best temperature zone, reduce the energy consumption of cooling system, save more fuel, and lower the working noise of vehicle.

* The high pressure hydraulic system effectively reduces the volumes of hydraulic units, saves the usage quantity of hydraulic oil, and eases the maintenances.
