FIELD: transport.
SUBSTANCE: invention relates to machine building. Proposed track comprises rectangular-plate base. Plate inner side thickness is maximum at the center of mounting plane and minimum at side faces provided with beads. Two grousers are arranged in track base outer surface. Through trapezoidal-shape hole and two pairs of holes for bolt joint with caterpillar chain links are arranged between said grousers at the base center. Track is furnished with two stiffness ribs consisting of straight and arc-like sections. Said stiffness ribs are arranged outer surface in symmetry about crosswise axis of track symmetry between said grousers on said straight section and aforesaid holes for bolt joint. Width of straight sections of stiffness ribs is more than 1.4 times larger than width of arc-like sections. Transition from maximum base thickness to minimum thickness is made at α=10°-30° relative to mounting plane.
EFFECT: higher strength, redistribution of strains.
