Abstract: In the article the analysis of domestic traction drives for autonomous quarry dump truck of 240 t payload capacity is carried out. The manufacturers of traction electric equipment kits (TEEK), such as LLC "Sibelectroprivod", CJSC "PFTK ZTEO", LLC "Ruselprom" and JSC "Power machines" are marked. The characteristics of traction motors of each manufacturer are given. Dependences of torque on rotor rotations of electric motors under consideration together with electric motor efficiency isolines are presented. Traction and speed properties of 240-t autonomous quarry dump truck are estimated according to the technique of constructing dynamic characteristic of the machine. Preliminarily by the offered technique the dynamic characteristics of the developed dump truck with the different variants of the set of the traction electric equipment have been built. It is established that for different types of the drive efficiency difference for the typical mode reaches 4.45%, which is essential when considering the cost of operating the truck on the scale of its life cycle. As a result of the analysis the conclusion is made that the dump truck with TEEK of LLC "Ruselprom" meets the requirements in full, and in a typical mode of uphill movement the electric motor provides the highest efficiency of 97,05% in comparison with the considered drive variants.
