The places where construction machinery is active are mostly mining sites far away from ordinary human life such as mountains and deserts, and sometimes even work at a distance of 2,000 meters underground. There are many types of this kind of machinery, from mineral crushing machinery to cutting machinery, screening machinery, loading machinery, conveying machinery, etc., all of which operate continuously 24 hours a day. Any failure of any of these machines will have a great impact on the production at the mining site. In addition, due to the recent increase in the size of the machines, maintenance operations have become very difficult.
