FIELD: transport machine building.
SUBSTANCE: invention relates to crawler fixtures for vehicle thrust. Device has an elongated body having a surface and a longitudinal axis. Bracket is configured to attach elongated body to caterpillar band. To the elongated body the first device for adhesion to the ground and the second device for adhesion to the ground are functionally attached, which protrude beyond surface of elongated housing. First device for engagement with ground has multiple teeth arranged in line. Second device for engagement with ground has multiple teeth arranged in line. Line of the first appliance for engagement with the earth passes at an angle relative to the longitudinal axis of the elongated body and at an angle relative to the line of the second appliance for adhesion to the ground.
EFFECT: higher thrust of vehicle.
