HD22 Crawler Bulldozer

HD22 series bulldozers adopt advanced technologies such as centralized lubrication (optional), centralized pressure measurement and automatic track tensioning. They accept a variety of working devices and cabs, making them ideal for earth and stone construction and bulk scraping.

A Cummins NT855-C280S10 engine delivers strong torque with low fuel consumption. A highly reliable powershift transmission, stable torque converter and two-stage straight-tooth final drive transmit power efficiently.

Automatic fault diagnosis and full monitoring are standard; the one-piece cast instrument panel integrates air conditioning, electrics and instruments.

The steel-plate welded full box-type main frame is integral with the rear axle box, giving high impact load capacity and bend/torsion resistance, with high-quality welds for full life-cycle strength.

A semi-rigid suspension travelling system increases track ground contact area and raises tractive effort.

The ergonomic cab places shifting, steering and throttle on the left through a soft-shaft structure and the work equipment servo controls on the right; the seat and armrests adjust in four directions.

Standard straight-tilt blade; optional large single- or three-shank ripper with adjustable penetration angle for clay, frozen ground, gravel and compacted salt deposits.
