Rationale for vehicle parameters for the transportation of straw and hay

Vehicles for the transportation of straw and hay in loose pressed forms are considered. A scheme a transport vehicle hay, haystack truck, is proposed. The truck consists frame, wheels, trailer device, finger platform, mechanism loweringlifting front part sides, lowering-lifting rear platform. results studies to determine physical mechanical properties necessary rationale parameters presented. dependence coefficient friction oat straw, barley, winter wheat, millet, buckwheat alfalfa awnless brome on fingers loading unloading surfaces: soil, sod, asphalt, crushed stone load speed resistance introduction tip platform into density material angle inclination shown. determining angles during loading, stacks Recommendations use self-loading transporting form given.
