High Performance Used SHANTUI SD22 Bulldozer 220HP Semi-U Blade 23400kg Heavy

Used SHANTUI SD22 Bulldozer – 220HP Heavy-Duty Earth Moving Powerhouse

Introducing this Used SHANTUI SD22 Bulldozer, a robust heavy-duty crawler dozer engineered for large-scale earth moving, mining support, and major infrastructure projects. With 220 horsepower and a 23.4-ton operating weight, the SD22 delivers the muscle and productivity that contractors demand for production dozing applications. SHANTUI's decades of bulldozer manufacturing expertise are evident in this model's durable construction, reliable powertrain, and operator-friendly design. This unit has been thoroughly inspected and verified ready for immediate deployment.

Turbocharged Powertrain Engineering

Commanding this SD22 is a 220-horsepower turbocharged diesel engine that develops peak torque across a broad RPM band, providing responsive power for heavy dozing through compacted materials without the engine lugging. The engine's mechanical fuel injection system is prized for its field-serviceability and reliability in remote job sites where electronic diagnostic support may not be available. The high-capacity cooling system incorporates a large radiator core and hydraulically driven fan that modulates airflow based on actual thermal demand, maintaining consistent operating temperatures during continuous full-load summer operations.

The heavy-duty powershift transmission features three forward and three reverse speeds with a torque converter that automatically multiplies engine torque in response to increasing load. This characteristic provides seamless power delivery when the blade encounters hard-packed materials or buried obstacles, allowing the operator to maintain forward progress without manual gear changes. The transmission cooler is sized for the most demanding continuous operations, with a thermostat-controlled bypass for rapid warm-up.

Semi-U Blade and Production Capacity

The SD22 is equipped with a 6.4 cubic meter semi-U blade, an ideal configuration for production dozing applications where maximizing material moved per pass is the primary objective. The semi-U design combines the penetration capability of a straight blade with the material retention of a full U-blade, enabling the dozer to carry larger loads across longer push distances. The blade features replaceable cutting edges, end bits, and corner bits manufactured from through-hardened boron steel for maximum wear resistance.

The heavy-duty hydraulic system delivers rapid blade response with a variable-displacement piston pump providing hydraulic flow matched to demand. The blade lift cylinders feature cushioning at both ends of the stroke to reduce mechanical shock during aggressive operation.
