220HP Crawler Bulldozer SD22
Load and Unload Method:Front Discharge
Certification:CE, ISO9001: 2000
Production Capacity:4000 Units/Year
It's equipped with a hexahedron damping cab, which features a beautiful design, wide visibility, and comfortable operation, as well as a highly efficient charged engine, which has excellent power, reliability and a long service life.
It is also equipped with an improved hydraulic drive system with hydraulic control technology, front-extending anti-rolling frame and an advanced structure, providing reliable quality and convenient and flexible operation.
The SD22 uses Shantui's patented central lubrication technology, central pressure measurement and automatic track tensioning, as well as a GPS satellite positioning system.
With options such as straight tilt, angle, U type and semi-U type blades, single/triple shank rippers and a mechanical winch, the SD22 has various capabilities allowing it to adapt to and work in a wide range of earth moving projects.
The imported engine with original packing has strong power, and can meet the requirements of high-efficient work.
- Precise matching design with advanced energy conservation control can reduce the oil consumption of the machine.
- Low emission meets the Europe II standard.
- The adoption of new cooling fan and large-scale silencer lowers the noise of the machine.
- The adoption of the advanced turbocharging technique increases the highland adaptability of the machine.
- Automatic preheating system improves the working capacity in the low temperature.
- Unique fan cover with the shape of hopper opening greatly improves the air supply of the engine and the radiating capacity of the system, guaranteeing the successive high-efficient work of the machine.
- Restart prevention system effectively avoids the misoperation, and improve the use security of the machine.
