Significant portion of the annual calendar fund-time work of mining excavators spent on maintaining its working condition by carrying out preventive and repair regulatory activities and recovery in the event of emergency failures and maintenance and repair expenses constitute a significant proportion of the cost of excavation of mining rock. To ass...
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...
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. These oil-servicing mobile workshops provide the possibility to organize maintenance at facilities, situated far from each other, and quick delivery of everything...

... Thus, the high share of emergency downtime (9%) after making changes to the design of excavators, including the use of on-board diagnostic systems and the transition to centralized lubrication systems with the solution of their refueling problems [18], tends to decrease. It is planned that according to the results of all warranty work to improve the design of excavators, the share of emergency failures will be within acceptable limits (3.3-3.8%). ...
... Unit setting up and software updating can be performed through USB interface in the unit with the help of a computer or remotely through the onboard computing system. For data storing, a power independent SD-card is installed in the unit [13,14]. ...
