Description:
The bulldozer, also called dozer, is a piece of earthmoving equipment widely used in the construction site. There is a front-mounted dozer blade used to push solid forward to make formed land. The bulldozer is widely used for road construction, water and electricity engineering, farmland leveling, port building, mining and other construction conditions. We can offer all kind of bulldozer from 80HP to 420HP by introducing Komatsu and Caterpillar technology.
The main subassembly of a bulldozer includes: tracked chassis, protective driver cage, rear-mounted ripper claw and a variety of front-mounted blades. Bulldozer blade and the ripper are the primary tools of bulldozers or dozers. There are straight blade (S-blade), universal blade (U-blade), U combination blade that can be used in the dozer to push piles of large rocks. The ripper is equipped with a replaceable tungsten steel alloy tip that can be installed on the back of the bulldozer (dozer). It can let the large rocks broken into small rubble for easy handling and transport
