Abstract

This bachelor thesis is dealing with the calculation and construction design of globular track of large–scale excavator according to parameters of upper construction. Part of my job is also a basic calculation of drive of rotary device of this upper construction. This work clearly in the introduction is summarizing the designs of rotary devices of upper construction of large–scale excavators and is allowing for easier orientation in this issue. One chapter of research is summarizing rotary devices, which currently is operating in the localities Doly Bílina a Doly Nástup Tušimice. The principal aim of this work are basic design considerations on the issue of globular tracks, with regard to relevant working and operating load and weather conditions.
