During the use of equipment in a mine in Shandong before 2016, frequent running, dripping, dripping, and leaking of the hydraulic system occurred, which caused heavy maintenance and high cost of spare parts. After fully introducing equipment operation and maintenance on-site services, the impact time of mechanical and electrical failures was reduced by 27%, and the use of spare parts was reduced by 18%. At present, this customer has become a model unit for Shandong coal mine equipment.
