Abstract. The work is devoted to ways to improve the efficiency of preparatory and excavation works in road construction using bulldozers equipped with universal working equipment. Studying the state of the bulldozer Park of road construction organizations of the city of Bryansk and the Bryansk region, it was revealed that the Park contains obsolete bulldozers.

In this paper, the authors proposed options for improving the university of the working equipment of the bulldozer with the addition of a controlled knife system or controlled lower sections. At the equipment-driven knife system, the working equipment of the bulldozer is characterized in that the edges of the bottom of the blade of the inserted knife system imposed on the surface of the blade, consisting of metal sheets with cutting edges, stiffeners and connected to gidrol linkami their management by means of brackets , and with a blade – with the help of duosonics, hydraulic cylinders control the cutter systems, BAP-pyatsya the edges on the back side of the blade with eyes limited to residing their turn to increase the rigidity of the structure. If necessary, the cutting knives can be replaced with a cargo fork to effectively pick up the goods.

When the equipment controlled the lower sections of the working equipment is characterized in that the push bars have cutouts for the installation of cross beam and pivotally connected via axles to the main building-som of the blade, which has a pivotally mounted visor with snarling face and eyes with hydraulic cylinder control. The lower sections are connected to the lever by means of hinge rods. The expansion of technological capabilities is achieved through the installation of an additional module-a loosening tooth with a tip or a cargo fork.
