The process of co-operation dump working bodies with the developed soil is one of determinative duty cycle machines for earth-moving transport works. Character passing of process carries out the considerable influence on the construction of earth-moving transport machines. Passing process of cooperation dump working body machine with soil depends on the technological setting machine, namely from a kind of a robot, that is executed by a machine, physical and mechanical properties of soil and method of his destruction, geometrical parameters of working body, parameters of the mode digging (depth of cutting, cutting corner, corner setting of working organ in a plan and etc.), that determine power and power parameters of working process machine. Possibility optimization of geometrical parameters telescopic working body of bulldozer to different ground to the terms and technological operations will allow rationally to use hauling and coupling descriptions of machine, promote her productivity and universality. Purpose. There is a review and analysis of existent theories of cooperation of dump working bodies with soil and development, on their basis, algorithm of optimization calculation geometrical parameters of dump bulldozer telescopic type depending on the ground terms and hauling and coupling descriptions of base machine, determination of his productivity at digging and portage soil. Conclusions. On the basis of hauling balance the algorithm optimization of geometrical parameters dump bulldozer telescopic type is worked out after the generalized criterion optimization ПNG depending on engine of base machine and physical and mechanical properties of the developed environment power.
