Medium-Duty | Bulldozer 426F2

Bulldozers can be found on a wide range of sites, mines and quarries, military bases, heavy industry factories, engineering projects, and farms.

Typically, bulldozers are large and powerful tracked heavy equipment. The tracks give them excellent ground-holding capability and mobility through very rough terrain. Wide tracks help distribute the bulldozer's weight over a large area (decreasing ground pressure), thus preventing it from sinking in sandy or muddy ground.

Because of these attributes, bulldozers are often used in road building, construction, mining, forestry, land clearing, infrastructure development, and any other projects requiring highly mobile, powerful, and stable earth-moving equipment.

Blade
The bulldozer blade is a heavy metal plate on the front of the tractor, used to push objects, and shove sand, soil, debris, and sometimes snow. Dozer blades usually have three varieties:

1. A straight blade ("S blade") is short and has no lateral curve and no side wings, and can be used for fine grading.
2. A universal blade ("U blade") is tall and very curved, and has large side wings to carry more material.
3. An "S-U" (semi-U) combination blade is shorter, and has less curvature and smaller side wings. This blade is typically used for pushing piles of large rocks, as at a quarry.
Blades can be fitted straight across the frame, or at an angle, sometimes using additional tilt cylinders to vary the angle while moving. The bottom edge of the blade can be sharpened, e.g. to cut tree stumps.

Ripper
The ripper' is the long, claw-like device on the back of the bulldozer. Rippers occur as a single (single shank/giant ripper) or in groups of two or more (multishank rippers). Usually, a single shank is preferred for heavy ripping. The ripper shank is fitted with a replaceable tungsten steel alloy tip, referred to as a boot. Ripping rock breaks the ground surface rock or pavement into small rubble, easy to handle and transport, which can then be removed so grading can take place.
