Design and operation features

To improve ease of operation, the SD22 shantui machine has been designed with a block design that facilitates disassembly and reassembly of the units. Parts and units that are subject to maximum wear and damage during operation were placed in the shock zone. The machine has a short base, allowing to work in cramped conditions. Chains of different widths and configurations were incorporated into the design. Therefore, the best option for certain operating conditions was chosen. The main elements were placed on a sturdy frame and the street bikes were connected to the frame to reduce wobbling.

The Shantui SD22 used a suspension with a compensating rod. Track shoes were supplied, each with its own tunnel. The chassis used six rollers with 2 double-row and 4 single-row rollers on each side. Two more track rollers were used on the belts. The track division was 560 mm. The basic system had 38 rollers on each side.

The Shantui SD22 had a complex transmission with multiple factory assemblies:

  • Single-stage single-phase torque converter with 3 elements;
  • Planetary gear;
  • Lamella clutch.

The main elements were connected through a hydraulic system. The main drive was a spiral bevel gear with a 1-speed gearbox. Similar to other products, Shantui SD22 received a standard turning clutch with oil bath. The swing brake was housed in an oil bath and controlled hydraulically. The axle drive consisted of a 2-speed spur gear, complete with spark lubrication system. The bulldozer’s gearbox had three forward and three reverse gears.
