Ports occupy an important position in the transportation and overseas trade of various countries, and mechanical equipment is an important part of the port. Without the normal operation of mechanical equipment, the port cannot operate normally. Therefore, mechanical equipment, as the "heart" of the port, occupies an indispensable status. In order to improve the long-term utilization rate of port equipment, equipment owners need to maintain it regularly.
