Its working equipment utilizes hydraulic pilot control and is equipped with a new-generation operator system, delivering superior construction performance.

Multi-Purpose: Tailored configurations are available based on operating conditions and environments, including blade, ripper, tow frame, and winch attachments. Custom development options maximize personalized customer requirements.

Power Options: The powertrain can be configured with the Heavy Duty NT855-C280S10 or QSNT-C235, or Weichai WP12 engines. Engine rated power is increased to 170 kW, delivering robust power, intelligent efficiency, and low fuel consumption.

Hydraulic System: Equipped with a fixed-displacement gear pump, the system achieves pressures up to 14 MPa. Operation utilizes mechanical linkage combined with servo valve control, reducing operator effort and enhancing overall operational efficiency.

The 22D bulldozer achieves perfect matching between the torque converter and engine. The hydraulic torque converter reaches up to 87% efficiency, reducing rated fuel consumption by 4.5% while increasing maximum torque by 5%. This delivers optimal output balancing power, efficiency, and energy consumption. 

The ergonomic hexahedral integrated cab offers spaciousness, excellent visibility, minimal vibration, tight sealing, and low noise. It can be configured with FOPS/ROPS as required for safety and reliability. Equipped with electronic hand and foot throttles for precise and comfortable operation, it features premium interior trim as standard, paired with climate control for a more enriched, user-friendly driving experience, ensuring a more comfortable and safer operating environment.

The H22D bulldozer boasts low maintenance costs and rapid servicing. Its intelligent display terminal with GPS fault detection accurately diagnoses issues, reducing repair time and costs.

The 22D bulldozer adapts to diverse operating conditions. Tailored versions address specific challenges in coal mines, deserts, soft ground, forestry, extreme cold, sanitation, and rocky terrain, fully meeting customized customer requirements.
