Abstract:

Theoretically is estimated the lateral movement of unit at transversal operation on slope that would be caused by lateral skid of tires as well as by slipping. Due the value of lateral movement are determined such operational characteristics of tractor unit, as coefficient of movement resistance, traction force utilization factor, velocity utilization factor, time utilization factor, coverage utilization factor, and so on. Are obtained design formulae by hour and shift theoretical and actual efficiencies.
