Design and Operating Features

Shantui SD23 is designed for use in a variety of climates. This is due to the presence of Japanese components and clever dozer design. The chassis is the company’s own development and is distinguished by its durability. The format produces individual modules that are integrated into the design. This solution reduces maintenance and track replacement time. Additional chains are available for mounting on dozers with different track widths and types. At the same time, the undercarriage is tested for tenacity and strength to guarantee a long service life. A compensating weight suspension is used as the undercarriage.

Another feature of the Shantui SD23 is its high overall stability. The track drive is mounted on 2 track rollers and 7 support rollers on each side. The track rollers are made by a watering method. 78 large bottom plates provide low ground pressure and excellent buoyancy.

The shantui SD23 uses a reliable new transmission with 6 gears (3 forward, 3 reverse). It consists of:

  • Single phase single stage torque converter with 3 elements;
  • Planetary gears with forced lubrication, plate clutch and shift reservoir;
  • Axial drive, supplemented by a 2-speed head gear and splash lubrication device;
  • Continuously closed, hydraulically actuated lamella rotary clutch operating in oil;
  • Floating clutch brake type riement in oil bath. Control is via a hydraulically-actuated foot pedal.

Bulldozer is equipped with 2 hydraulic systems that are not connected to each other:

  • A hydraulic chassis drive system that maintains the necessary oil pressure supplied to the hydraulic transformer. Its operation ensures the lubrication of gears, lags and other elements that are used in the braking process and are subjected to friction;
  • The hydraulic system of the main working tools, which ensures the operation of the ripper. As a result, the shield and hydraulic cylinder pistons can move forward and backward while maintaining pressure in the hydraulic cylinders.
