In the use of overhead hoist for lifting, various moving parts will inevitably wear, loose connectors, oil deterioration, and corrosion of metal structures, which will cause the technical performance, economic performance and safety performance of overhead hoist to be reduced to varying degrees. Therefore, before the wear and tear of the parts of overhead hoist has reached the level of failure, in order to prevent and eliminate hidden dangers and ensure that the overhead hoist for lifting is always in good condition, the overhead hoist should be maintained and maintained.
The maintenance and maintenance of overhead hoist for lifting can play the following roles.
1. Make the overhead hoist for lifting have good technical performance.
2. Make the overhead hoist for lifting have good performance, strengthen the protection of structural parts, keep the connection firm, the action and function of the electro-hydraulic components are normal, avoid abnormal vibration due to electromechanical factors, and meet the normal use requirements of overhead hoist.
3. Make the overhead hoist for lifting safe to use.
4. Comply with the relevant environmental protection standards stipulated by the state and departments.
5. Reasonably and effectively prolong the service life of overhead hoist for lifting. Through the maintenance of overhead hoist, the repair interval of the crane or mechanism can be effectively extended, including the overhaul period, thereby prolonging the service life of the crane.
