DEVELOPMENT AND EXPERIMENTAL RESULTS OF A NEW CONSTRUCTION OF THE ELEMENT OF PROTECTION OF THE BASE OF THE JAVE PART OF QUARRY EXCAVATORS

Аннотация

An analysis of the performance of quarry hydraulic excavators shows that many excavators used in mining operations operate at lower productivity than those specified in the technical description. This can be caused by unexpected interruptions during operation, rapid failure of parts and unreliable operation of excavator personnel. This article discusses the development of a protective element at the base of the jaw section of an excavator bucket that is technically and cost-effective in increasing the efficiency of quarry excavators. In addition, the results of experiments and their analysis of the proposed element of the protection of the base of the improved bucket jaw.
