Types of Bulldozers
Some bulldozers are modified by replacing the blade with a large bucket and hydraulic arms that are used for lifting and lowering of the bucket. Loader tractors are created, thus making the bulldozer valuable for soil excavation, and loading the soil into trucks. Other functions of bulldozers are for deforestation, earth removal, and ground flattening. Heavy bulldozers are generally engaged for terrain leveling to organize it for construction. The construction is mostly executed by the use of small bulldozers. Broadly we can categorize bulldozers based on the following factors.
Type of Blade
Different bulldozers use different types of blades and depending upon the type of blade used, bulldozers are used at different construction sites. For grading of surface and evening of soil, straight blade bulldozers are most useful. Another type uses a U blade, which is also called a universal blade. It is best suited for pushing, hauling, and scooping works. However, one cannot use straight blade bulldozers or U blade bulldozers for very heavy works, and it will require working with a combination blade. Combination blade bulldozers can do petty jobs like pushing and cleaning debris and also work with heavy loads at the same time.
Hybrid bulldozers are advanced equipment making use of electronic components and are equipped with a combination of blades that can work in water logged and very hard conditions simultaneously. Today we have bulldozers that can work even in swampy conditions. We have customized blades too that can be mounted over any type of vehicle like a tractor, all-terrain vehicles, and skid steers.
Based on mobility, track and tire bulldozers are the two major types of bulldozers. A tire bulldozer will have better mobility and are light in weight. However they cannot perform heavy lifting tasks as compared to track bulldozers, which is the second type of bulldozers based upon their mobility. Track bulldozers are suitable for hard surfaces as they can damage the soft surface. For hauling purposes, track bulldozers are suitable, whereas for leveling and moving materials, a tire bulldozer is the best option.
