FIELD: construction.
SUBSTANCE: bulldozer equipment comprises main and additional working elements. The main working element is arranged with two symmetrical dump sections relative to the longitudinal axis of a pushing frame and with mechanisms for movement of dump sections in a horizontal plane. Dump sections of the main working element form an isosceles triangle together with a cross beam of the pushing frame in plan, the top of which is arranged on the longitudinal axis of symmetry of the pushing frame. The additional working element is arranged in the form of at least two dump sections and a mechanism for displacement of the latter in a direction perpendicular to the longitudinal axis of symmetry of the pusher frame. Dump sections of the additional working element are arranged symmetrically relative to the longitudinal axis of symmetry of the pushing frame.
EFFECT: increased efficiency of works with simultaneous reduction of energy intensity of soil movement process.
