The scope of bulldozers refers to work on Earth. They are often used to clear the territories from the upper layer of the soil so that there are no roots, residues of stumps and other vegetation on it. At least often they are used to cut irregularities in the planning of the territory. With the help of bulldozers, the hollows are filled up and excess soil is removed, the embankments are built for the construction of roads. This machine will provide irreplaceable assistance when erecting a barrier dam or develop a pit. Of the companies, we can recommend Shantui bulldozers known for their high quality.
There are two types of bulldozers, if we consider the method of installing the dump. The first type of machines have a dump that is a non -rotten. The second type implies a machine that has a rotary dump and can establish various provisions for it, which makes it possible to do the work better. Work on such a machine gives more opportunities for the operator. In order to increase the productivity of the machine on light soils, the dump is supplied with special lateral openings.
For bulldozers with hydraulic control, the dump is risen and drops using two or one hydraulic cylinder. Hydraulic cylinders are installed in the front of the machine, on her tuitioners. Due to the fact that the dump is forced, and with effort, you can flex the knife in any type of soil, even the most severe. At the same time, the position in which the dump was established is unchanged and makes it possible to carry out work under a clearly defined mark.
An important indicator for the bulldozer is the power measured in horsepower. But this is not the only important indicator. The good work of the bulldozer will also depend on the type of chassis and width of the dump. The width of the dump will be directly dependent on the power of the machine. Power can reach from 55 to 250 horsepower, depending on the dimensions of the dump and the chassis. The chassis is a wheeled and caterpillar species. A car with a wheeled part is more practical in transportation, but less effective when working on complex soils. The caterpillar bulldozer can work on almost any soils, but complicated in transportation. Also, the disadvantage of the caterpillar machine is increased weight. If the distances are small, then cars can go their own. If you need to overcome a long distance, then special platforms or trailers are used on which the equipment is transported.
