Chinese Earthmoving Machinery 21Ton 240HP Bulldozer SD20-B5 for Sale

 

Product Description

Power System

The modular design is adopted to achieve easy assembling and disassembling and simple repairs.

The Weichai WP12 engine conforms to the China-II non-road machinery emission regulation, featuring strong power, low fuel consumption, high intelligence and efficiency, high parts universality, and low maintenance cost.

The modular units adopt cushioned installation to isolate the vibration and transmission and promote the machine reliability and life.

The normally-closed brake system is adopted to apply the braking whenever the engine is stopped, featuring high safety.

The four-point semi-suspension shock-absorbing installation reduces the machine vibration and improves the driving comfort.

 

 

 

 

 

Drive system

The normally-closed brake design is applied so that the machine is braked automatically after the stop of engine to ensure high safety.

The shock absorbers in crossing shaft rubber block structure are applied to effectively mitigate the vibration from the engine and protect the engine and drive system.

 

 

 

 

 

Driving/Riding Environment

The integral ergonomic hexahedral cab features large space, excellent vision, and good airtightness.

The single accelerator pedal features comfortable operations.

The extensively adjustable seat and armrests provide the driver with the most comfortable operation;

The cab adopts integrally sealed shock-absorbing system and sound-absorbing sponge to realize low vibrating noise.

The optional A/C and heating system, the intelligent display and control terminal with integrated instruments, cigarette lighter, USB charging port, radio, toolbox, and fire extinguisher are installed to provide more abundant personalized driving/riding experience and guarantee the comfortable and safe driving/riding environment.

The safety passage system of the machine guarantees the driver's safety.

 

 

 

 

 

Working adaptability

The undercarriage system features long ground length, high ground clearance, stable driving, and excellent trafficability.

Depending on specific working condition, the semi-U blade, straight tilting blade, angle blade, three-shank ripper, traction frame, and winch can be installed to achieve power operating capability.

The standard LED working lamps improve the illumination capability and achieve higher safety and reliability during nighttime operations.

 

 

 

 

 

Easy maintenances

The structural parts inherit the excellent quality of mature products.

The electric harnesses adopt seamless corrugated pipes and deconcentrators for branching, featuring high protection grade.

The core electric and hydraulic parts adopt imported products, featuring stable and reliable quality and extremely high reliability;

The modular structure design of the machine features easy disassembling and assembling, simple repairs, low failure rate, and easy maintenances.
