FIELD: transport engineering; self-propelled vehicles. ^ SUBSTANCE: proposed swamp tractor can be used for towing freight trailers. Said tractor with hollow supports at edges provides minimum load on surface of swamp which, firstly, brings to minimum resistance of swamp to movement of tractor and, secondly, unloads crawler propulsion unit making it possible to use track links of increased height of horns. ^ EFFECT: considerable increase in tractor pulling force owing to difference in lower edges of idler wheels and driving sprockets equal to height of horn. ^ 2 dwg |
