The driving system of bulldozer adopts eight-girder windingtype and balance beam semi-rigid suspension structure, which guarantees its goodcushion effect, steady walking and comfortable operation. The steel-sealed andhexahedral cab can be equipped with air conditioner, anti-roll device, electricwashing device, ripper and different blades, which can meet different workingneeds.
The bulldozer is semi-rigid suspended, power shift, hydraulically controlled andtrack-type. It is applicable for road construction, water and electricity engineeringfarmland leveling, port building, mining and other engineering conditions.
