Abstract. Study of travel mechanism in the walking excavators is a very important task, practical significance of which is determined by the need to find ways of how to improve undercarriage in the excavator-draglines through modernization of the ski bearing faces of the travel mechanism in the walking excavator.

Data of such studies are extremely necessary for determining actual parameters, which characterize operation of travel mechanism in different conditions, and finding out reasons of unsatisfactory traveling of excavators on different soils.

In this article, a new design of bearing elements for the skies is presented, which speeds up traveling of walking excavator due to the ski reduced skidding at each step. Further, results of experimental studies in conditions of rocky and weak soils (clay sands) are presented, which showed that implementation of the new design of bearing elements would greatly increase the excavator-dragline floatation.

Keywords: excavator-dragline, walking motor, ski, bearing elements
