When the crane is in use, various moving parts will inevitably produce wear, loose connections, oil deterioration, and corrosion of the metal structure, which will cause different degrees of reduction in the technical performance, economic performance and safety performance of the crane. Therefore, in order to prevent and eliminate hidden dangers and ensure that the crane is always in good condition, the crane should be maintained and maintained before the wear of parts in the daily maintenance of the crane has reached the level of affecting the failure of the crane.
Good crane maintenance can play the following roles.
- Crane maintenance ensures that the crane often has good technical performance, is the normal and reliable operation of each organization, and improves its intact rate, utilization rate and other management indicators.
- Ensure that the crane has good performance. The maintenance of the crane can strengthen the protection of the structural parts, keep the connection firmly, the movement and function of the electro-hydraulic components are normal, avoid abnormal vibration due to electromagnetically factors, and meet the normal use requirements of the crane.
- Ensure the safe use of the crane.
- Comply with relevant environmental protection standards stipulated by the state and departments.
- Reasonably and effectively extend the service life of the crane. Through the maintenance of the crane, the repair interval of the crane or mechanism is effectively extended, including the overhaul period, thereby extending the service life of the crane.
