Bulldozer type equipment

FIELD: transport.

SUBSTANCE: invention relates to equipment bulldozer type. Equipment is located behind wheeled machine frame, reinforced by cross member, or at aft body sheet track or wheel machines. Equipment includes a dump, total length of cutting edge of which is not less than size of machine by width, side track machine rippers, teeth for forced penetration of dump and lateral openings in blade for automatic shank out thereof, thrust rods or length-adjustable flexible multi-link rods, retaining dump in working position. Number of parts of dump is increased up to three, each in upper part is hinged in two lugs with machine frame or two lugs with machine body bottom feed sheet. Two side parts are connected to each eye is pivotally via their teeth on rear side of dump, with mating lugs thrust bars or through eye of teeth on face side of dump, with mating lugs of flexible multi-link rods. Side parts of dump are retained in working position, pivot joints with mating lugs at crosswise beam amplification frame for fastening of thrust rods or mating lugs on aft body sheet for fastening flexible m ulti-link rods.

EFFECT: technical result is provision of self-entrenching vehicle, as well as higher efficiency of construction bunkers and other shelters in limited time.

FIELD: machine building.

SUBSTANCE: invention relates to main frame and machine with said main frame. Main frame (10) comprises front frame (21), rear end frame (22), opposite first and second side frames (23, 24) extending between the front frame and the rear end frame. connecting the front frame with the rear end frame. First side frame (23) so as the second side frame (24) are formed, respectively, by the first side plate (25) and the second side plate (26), the second side plate (26) is thicker than the first side plate (25), and at least one hole (27, 28)is formed in the second side plate (26).

EFFECT: according to the invention, the first side plate has relatively small thickness, and at least one hole is formed in the second plate which is thicker, and the result is a light weighting and strong frame.

Trenching machine // 2593504

FIELD: construction.

SUBSTANCE: invention relates to excavators and is intended for digging trenches. Trenching machine contains one or more rocket engines directed to a place of desired ground excavation. Structural design is made in three versions. In the first version the trenching machine has a fan directed to the dug trench. In the second version the trenching machine has a transversely located ahead and/or behind reflector in the form of letter V or of "gull wing” type. In the third version the trenching machine is made as a crossbar temporarily transversally attached to two tanks to support the rocket engines, tanks with rocket fuel, and an engine with the fan.

EFFECT: technical result is increased speed of ground excavation.
