As a result of the studies, the possibility of assessing the state of the working surfaces of mining machines, in particular bearing assemblies as a whole without disassembling the gearbox, is confirmed. An innovative solution in this matter is to ensure the delivery of the lubricator to tribolcoupling through the channels of the lubrication system...

The article discusses various factors that have a significant impact on the performance of EKG-32R type powerful mining excavators. It was revealed that the most adverse effects are weather conditions that are different from the nominal ones for which mining machines are designed. The climatic factor includes the impact of solar radiation, low and...

Nowadays, the development of remote regions of Russia related to energy security is increasingly relevant. Existing production technologies have a significant anthropogenic impact on the environment. To reduce the negative consequences of this impact, it is necessary to develop complexes of mining equipment capable of complex processing of excavate...

An experiment was conducted to confirm the reliability of the evaluation of the technical condition of transmission elements during operation in terms of the magnitude and nature of the acoustic emission signal, while completing the negative effect of the artificial environment on the durability of the transmission elements. Thus, the results of th...

Currently in the mining industry there is an observed increase in demand for portable lubrication and filling units used by technical maintenance and repair of different quarry machinery.
