DT22D Desert Version Bulldozer Overview
The DT22D Desert Version Bulldozer is a specialized crawler bulldozer within the SD22 series, engineered for extreme arid and loose-surface environments such as deserts and Gobi regions. The DT22D Desert Version Bulldozer is designed to deliver stable traction, controlled ground pressure, and reliable earthmoving performance in conditions where terrain stability is limited and sinking resistance is essential for continuous operation.
Primary Operating Scenarios
The DT22D Desert Version Bulldozer is developed for demanding earthmoving and infrastructure projects in dry, sandy, and low-bearing-capacity environments.
Desert infrastructure construction
It is widely used in oilfield road construction, mining access roads, and camp site preparation in desert regions. The machine maintains stable performance on loose and shifting terrain, ensuring efficient construction progress.
Large-scale arid zone engineering projects
The DT22D Desert Version Bulldozer is suitable for excavation, grading, and backfilling operations in highways, railways, and airport construction projects located in arid regions with sandy soil conditions.
Soft ground and low-bearing capacity applications
In environments requiring controlled ground pressure, it can also be used in select urban construction, port development, and similar earthmoving projects where stability and traction are critical.
Desert Terrain Performance and Stability
The DT22D Desert Version Bulldozer is optimized for high mobility in sandy environments. It features 660 mm wide track shoes and a reinforced undercarriage system, achieving a ground pressure of approximately 56 kPa.
This configuration effectively reduces the risk of sinking in loose sand while ensuring continuous traction and stable operation in desert terrain conditions.
Power System and Transmission Efficiency
The machine is powered by a high-performance turbocharged diesel engine with a flywheel power output of 175 kW, providing strong and consistent power for heavy-duty earthmoving tasks.
The transmission system integrates a torque converter and a planetary power-shift gearbox developed by Shantui. This mature hydraulic-mechanical system ensures smooth power transfer, responsive operation, and high reliability under continuous load conditions.
Structural Design and Operational Reliability
The chassis system of the DT22D Desert Version Bulldozer is designed to maintain stable ground contact and balance during operation on uneven and shifting terrain. This improves control accuracy and reduces slippage in sandy environments.
The overall structural layout enhances durability and ensures long-term operational stability in harsh desert working conditions.
Working Equipment and Functional Flexibility
The machine is equipped with a straight tilt blade as standard, with optional angle blade, U-blade, and semi-U blade configurations available to meet different project requirements. With a blade capacity of 6.4 m³ and a maximum digging depth of 540 mm, it supports efficient material handling and site preparation.
Optional single-shank or three-shank rippers further enhance its capability in compacted or semi-hard ground conditions.
