Key Features
Engine: Equipped with a CUMMINS engine that meets China's Tier II non-road emission standards. It offers strong power, high efficiency, energy-saving capabilities, adaptability to various diesel fuel qualities, and low maintenance costs.
Transmission: The gearbox uses a planetary gear structure with hydraulic valve control to switch between forward, reverse, and different gear modes. It adopts a multi-disc clutch, hydraulic engagement, and forced lubrication, providing three forward and three reverse gears.
Cooling System: A sealed system maintains internal pressure to improve coolant evaporation temperature and cooling efficiency. The fan, powered by the engine, provides forced airflow to enhance heat dissipation.
Electrical System: Waterproof connectors, upgraded relays, and molded gauges effectively reduce electrical faults. The integrated control box combines the A/C system, electrical components, and instrumentation, ensuring a sleek and efficient interior layout.
Chassis: The main frame is welded from high-strength steel plates and connected to the rear axle housing, offering excellent resistance to impact, bending, and torsion. High-quality welding ensures long service life.
Undercarriage Suspension: The oscillating beam suspension structure connects the beam to the frame and walking system, effectively transferring operational loads and enhancing stability, especially for small bulldozers in complex conditions.
Custom Attachments: A variety of blades and attachments, including straight-tilt blades, U-blades, angle blades, coal blades, rock blades, sanitation blades, rippers, and towing frames, can be installed to suit specific job requirements. Optional LED work lights improve night-time visibility, ensuring safety and reliability.
Cabin: The hexagonal cabin provides spacious interiors and wide visibility. Optional ROPS/FOPS structures are available for enhanced operator safety.
