D165
To meet the market demand, D165 bulldozer is developed by absorbing advanced techology from abroad. It boasts reasonable overall arrangement, beautiful design, flexible and comfortable driving, superior performance, convenient maintenance, safety and reliability.
Technological Advantages of D165 Bulldozer
1, We adopt SDEC C6121ZG57 diesel engine under CAT license, which use CAT C3306 engine technology with high coefficient of torque reserve and low fuel consumption and high reliability.
2, The appearance of the vehicle is based on optimization design.
3, Hydrauliclly powered, automatic speed change, shift the gears without stop the vehicle.
4, 3 elements, single stage and single phase torque convertor features high efficiency and capacity.
5, The updated hexahedral cab features outstanding visibility and good tightness.
6, Using the triangle spline and the gear of crowned teeth and tip relief in the final drive to average the loads on the trans-mission components for more stability, prolong the lifetime.
7, New blade is more durable and capacious.
8, Implement controls are piloted to minimize operating effort.
