Scope of Application:
The HD22 Series Bulldozers integrate advanced technologies such as centralized lubrication, centralized pressure monitoring, and automatic track tightening systems. They can be outfitted with multiple work attachments and operator cabs to accommodate diverse operating conditions. Designed as ideal and highly efficient equipment for earthwork, rock construction, and bulk material scraping, they excel in demanding environments where precision and durability are critical.The Cummins QSNT-C235 engine meets your demands for power and reliability. It improves fuel economy compared to previous models, delivering robust torque output and low fuel consumption for exceptional overall fluid efficiency.
Highly reliable power shift transmission, a stable torque converter, and a two-stage spur gear final drive ensure efficient power transfer.
Automatic fault diagnosis and real-time monitoring capabilities are integrated for proactive maintenance. The cast-in-one instrument panel combines air conditioning, electrical controls, and gauges into a sleek, luxurious design.
Robust structural integrity: The main frame employs a fully enclosed box structure constructed from welded steel plates, integrated with the rear axle housing. This design offers superior impact resistance, bending strength, and torsional rigidity. High-quality welding ensures durability throughout the machine's lifecycle.
Ergonomic operator environment: The adjustable driver's seat and armrests allow personalized comfort. Controls for shifting, steering, and throttle are positioned on the left side with a flexible shaft mechanism, while work attachments are operated via a servo control system on the right, ensuring smooth and agile handling.
Standard straight-blade design provides exceptional cutting force. The machine can be equipped with a three-shank ripper for penetrating tough clay and frozen soil, delivering high efficiency and unparalleled penetration power.
This combination of advanced engineering and user-centric design makes the HD22 Series Bulldozer a versatile and high-performance solution for demanding earthmoving, rock excavation, and heavy-duty scraping operations.
