  • Design of articulated pneumatic roller for construction of winter highways

    In the Russian Federation, there are settlements that can only be reached by special equipment: swamp walkers, SUVs. Permanent access to such settlements is hindered by swamps, rivers, etc. Temporary winter roads "autozymniki" are laid to such settlements in winter. The construction of "autozymers" includes several stages: the preparatory stage, the main stage of construction, operation of the autozymer and disposal. If a temporary winter road passes through swamps, then it is advisable to push such soils with tractors with widened tracks or tracked tractors. The article proposes the design of a articulated pneumatic roller for the construction of winter highways, and also carried out a design calculation including: calculation of resistance to movement, hydraulic calculation, selection of hydraulic equipment.
