Bulldozer

The high reliability power shift transmission, the stable hydraulic torque converter, and two-stage spur gear final drive feature high power transmission efficiency.

The engine can run normally and reliably under all load conditions and all hot environments required by the user, without overheating.

Product-Features

1.The high reliability power shift transmission, the stable hydraulic torque converter, and two-stage spur gear final drive feature high power transmission efficiency.

2.The engine can run normally and reliably under all load conditions and all hot environments required by the user, without overheating.

3.The semi-rigid suspension traveling system increases the ground area of tracks and improves the traction force of vehicle.

4.The ergonomically designed driver seat and armrests can be adjusted easily in vertical and longitudinal directions. The gearshift, steering, and accelerator controls are arranged on the left side with the adoption of flexible shaft structure. The working device controls are arranged on the right side with adoption of servo control system to achieve lighter and more flexible operations and relieve the operating fatigue.
