During the use of the crane, 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 annual crane maintenance and maintenance should be carried out before the wear of the parts in the annual maintenance of the crane has reached the level of affecting the failure of the crane.
Doing a good job in crane annual inspection can play the following roles.
1. The annual inspection of the crane ensures that the crane often has good technical performance, is that each organization works normally and reliably, and improves its integrity rate, utilization rate and other management indicators.
2. To ensure that the crane has good performance, the annual inspection 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 electromechanical factors, and meet the normal use requirements of the crane.
3. The annual inspection of the crane ensures the safe use of the crane.
4. Comply with relevant environmental protection standards stipulated by the state and departments.
5. Reasonably and effectively extend the service life of the crane. Through the annual inspection 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.
