Torque Converter and Transmission
Torque converter of the bulldozer has single-stage, three unites structure.
Our bulldozer has a stable power output which is of high performance.
Its planetary type power shift transmission is of three speeds forward and three speeds reverse, which makes the shift of speed and direction quicker.

Travel Speed (in Theory 1900/min Engine Speed)

  Forward Reverse
First speed (km/h) 0- 3.32 0-4.00
Second speed (km/h) 0-6.26 0-7.57
Third speed (km/h) 0- 11.40 0- 13.87

Steering and Braking
The steering clutch is tightened by pressurized springs and separated by oil-type multi-powder-metal discs.
The braking system is made up of oil brakes, two-direction floating band brakes with mechanical foot pedals. The steering and braking can be actuated in one control device.

Transmission, Steering and Braking Operation
A single lever controls the operation of transmission, steering and braking. With three speeds forward and three speeds reverse, these operations can be controlled by one handle.

Undercarriage System
The undercarriage is made up of a section steel welded track roller frame with diagonal brace. The floating seals of track rollers, carrier rollers and front idlers are the same. They have long-service life and are leak-proof.

Number of track rollers 4 single-flange on each side; 2 double-flange on each side
Number of carrier roller 2 on each side
