A bulldozer with specialized dumps for moving coal, wood chips and peat rear tractor ballast weight is suspended from acting as a counterweight. To work in extreme situations when clearing blockages in the MOE used bulldozers Komatsu with blade 8 and 81) reduced width, which fit into the railway gauge. This allows a high degree of willingness to work as bulldozers with an attached blade are in the open platform in anticipation of an order for shipment. On the bulldozers of the middle class traction firm Liebherr uses hydraulically reamer, which the cab can be installed at any angle to the dumps. When transporting Bulldozers on trailer reamer turn back, and blade fits into the envelope. Similar dumps applies firm Fiat-Kobelco. Dumps for garbage collection are designed to move the waste to landfills. The shape of this straight blade, with increased width and curvature of the surface of the front plate, as well as the height of the peak, roughly equal to the height of blade.
When using such dumps tractor units subject to additional alterations to protect them from sharp objects and abrasive materials, suspended behind the tractor ballast weights. These dumps provide firm Saterrillar , Dressta and Liebherr . Kustorezny Blade (V-shaped), produced Saterrillar and Komatsu, intended for clearing overgrown with shrubs and low forests of the areas under construction. Lowered into position in the form of angled blade cutter formed by two cutting blades, glide on the earth's surface, cut shrubs and small trees and dump them into the sides, forming a passage for equal widths of blade. Security fence as a steel frame protects the tractor from damage if dropped cut trees. Kustoreznye dumps are made by firms Rimco and Rome. Dumps-stubbing – either dumps lattice form with teeth or teeth that are attached to the front plate straight blade. They are designed to extraction from the soil of large stones and tree stumps and transporting them to close the distance.
The tractor is equipped with top of an additional protective barrier. Such dumps produced by "Saterrillar, Komatsu, Liebherr, Rimco and Rome. The right choice consumer bulldozer blade is the main condition for achieving the best possible performance. First of all, we should evaluate the possibility of digging the ground blade, traction and performance characteristics bulldozer. The possibility of digging the soil are determined by the ratio of the maximum traction bulldozer to the length of the knife blade. The higher the value, the more stable soils can develop a bulldozer. Traction characteristics bulldozer estimated its operating weight, design of Track and transmission. Speed characteristics determine the cycle time of a bulldozer. The smaller its value, the above shall be the rate of working and vehicle movements, and hence higher productivity bulldozer. Engine power, per 1 m3 of loose soil in a prism drawing, in practice, is used to estimate selection blade on the ability to move the material with a large working speed. Transportation speed, especially reversing determine the return time a bulldozer to the starting position.
