PETERSBURG MACHINE-BUILDING PLANT LLC has modernized and launched production of bulldozer snow-cleaning equipment, which provides lifting of the snow mass before discarding, due to the use of an inclined dump sheet chute, which facilitates and accelerates the clearance of the territory. The developed designs of bulldozer equipment make it possible to install it both in front and behind the tractor.

Currently, wedge-shaped bulldozer equipment is manufactured with trough angles from 7 to 15 degrees, with a blade width from 3200 mm to 3700 mm.

For wedge-shaped bulldozer equipment with a blade width of 3700 mm, a model of a bulldozer blade with flaps has been developed, with an installed hydraulic drive for changing the position of the flaps. The width of the machine in the transport position (flaps folded) is 3150mm, which ensures the transportation of the machine without dismantling the bulldozer equipment on the railway platform and trawl. These modifications of bulldozer equipment are designed for punching roads in virgin snow, and are widely used in the construction and maintenance of winter roads. The design of wedge-shaped bulldozer dumps, which ensures the lifting of snow masses and their throwing away at a higher height, facilitates the clearing of territories and increases the speed of work, as a result, labor productivity increases, and the cost of road maintenance and maintenance is reduced.

Also, a deep modernization of bulldozer equipment for the construction and maintenance of roads, model DM-15, was carried out. The change in the design of the blade provides for the lifting of snow masses and throwing them at a higher height than it was before, which facilitates the clearing of territories and increases the speed of work, as a result, increases labor productivity, reduces the cost of maintenance and road maintenance. After modernization, this bulldozer snow-cleaning equipment was given the SP-45 marking.

The structures of the above dumps have a box section and are made of alloy steel, with a front plate thickness of 10 to 12 mm, which ensures their greater rigidity and the ability to withstand very heavy loads and allows them to be used, in addition to clearing areas of snow, when working with heavy soils ...
