The bulldozer is a special construction machine with cyclic action on wheels or tracks. The main functions of the machine are performed using the blade (accessories), which helps it dig, cut, move soil, as well as perform a number of other works on construction sites and in places where the surface is inclined at significant angles: in quarries, hilly landscapes, etc.
To make the right choice, you need to understand exactly what goals you are pursuing when purchasing this special equipment. It is better to make the final decision based on the list of planned works, as well as the materials with which the bulldozer will work.
To choose the right model, both in terms of price and quality, it is important to understand the modification criteria. First of all, as a rule, the weight of the equipment is determined. If you need a bulldozer for building a small house, a standard size machine (20-25 tons) with a straight blade will do the job. If you need a bulldozer for the construction of larger buildings, it is better to opt for more productive machines with a powerful engine and a front blade. It is not difficult to guess which special equipment will be most effective with the correct ratio of power and weight. A heavy bulldozer for small items will be extremely unproductive. To see things more clearly, let’s look at the main traction classes of bulldozers:
- small class – weight up to 0.9 tons, engine power – 25-50 horsepower;
- light class – weight from 1 to 1.4 tons, engine power – from 50 to 130 hp;
- middle class – weight from 6 to 25 tons, engine power – from 140 to 210 hp;
- heavy class – weight from 25 to 35 tons, engine power – from 300 to 550 hp;
- extra-heavy class – weight over 35 tons, engine power – from 690 hp.
We also advise you to pay attention to the design features of the moldboards, as well as the type of work for which they are used. There are rotating, non-rotating and universal buckets. The group of non-rotating buckets includes straight, spherical and hemispherical buckets. For earthmoving and construction work, it is advisable to use straight, spherical and hemispherical buckets. Each of them can be equipped with a hinged roof. It should be noted that these types of molds are rotating and tilting. Straight mills can be used for jobs such as developing unfrozen soils and light rocky soils. Spherical moldboards can be used to move large volumes of light soil. The hemispherical moldboards combine the capabilities of the two previous models.
