Gearbox
This machine is equipped with transmission of planetary gear and multi-discs clutch hydraulic engaged and force lubricated {five transmitting lines in total). Forward 3 speeds and reverse 3 speeds can be gained hydraulically by actuating control valve.
Torque Converter
The torque converters are of the single stage, single phrase, 3 elements hydraulic type with reasonable structure and excellent reliability, which provide optimum matching with the machines. The outstanding transmissions comparing to the normal ones means the automatic adjustment to the field condition, gradually speed change, improved machine lifetime and traveling ability, easy maintenance, improved working comfort and torque limit set protection function.
Final drive
The final drive adopts double reductions of Spur gear pairs, planetary gear pairs to multiple torque and the power is transmitted to travel mechanism by driving gears. It features splash Lubrication and floating oil seal.
