FIELD: transport engineering.
SUBSTANCE: device is made in form of at least two rigid hollow prismatic structures with cross-section in form of triangle, with flat and/or relief side surfaces, with straight and/or curvilinear ribs, each of them is located on the appropriate side of the vehicle mover. Besides, the device has support side surface connected by means of the kinematic links with external surface on the mover element interacting with soil, support side surface in contact during self-recovery with soil, made solid and/or perforated, third support side surface made by spacer or spacers. At that length of the side ribs of each prismatic structure is comparable with width of the appropriate mover elements contacting with soil.
EFFECT: reduced size and weight of the device, reduced labour intensity of installation and dismounting.
