Bulldozer was widely straight shovel

hydraulic track bulldozer uses a wide range of earth-moving machinery is the most commonly used operating machinery, occupies an important position in the earthwork construction. But because there is no wing blade, capacity is limited, in the process will cause earth leakage on both sides, it is not too long haul, otherwise it will reduce production efficiency. Typically small and medium haul bulldozer was 30 ~ 100 m, a large bulldozer haul generally not exceed 150m, bulldozer economic haul distance 50 ~ 80m.
When the transport conditions, earth-moving equipment was lifted lift cylinders, hanging in front of bulldozers; when the bulldozer into the working condition, the lower earth-moving equipment, the blade into the ground, can bulldozing forward, rewind can ground. When the bulldozer for tractor operations, the soil can push device removed.
Typically, hydraulic drive system bulldozers pushed forward dig earth, when the flat ground or piled loose material, widely it straight shovel; shovel or unilateral spoil hillside, often using oblique shovel; shovel cut on the slopes hard soil or digging ditches, using the side shovel.
