The initial quality of the pre-production phase determines the lifespan of the crane electric hoist. However, to extend the lifespan of the electric hoist later on, proper protection and maintenance are indispensable. Appropriate protection and maintenance not only extend the service life but also enhance the flexibility of the electric hoist's operation.
The use of electric hoists is subject to many constraints. Generally, a trial run is required before use, and it can only be operated normally after a series of standard no-load operations. For electric hoists, it is crucial to prioritize the protection of the brake and reducer, as these are vital components that are also prone to issues. Regular inspections and maintenance, as well as timely repairs and replacements if damaged, should be conducted.
The maintenance of electric hoists is divided into maintenance during installation and maintenance during operation after installation. Whether newly installed or dismantled, electric hoists require a no-load operation to ensure proper functioning. Power-on operations are not allowed before installation and debugging; only after completion of the debugging can the hoist be powered on for a no-load test. For the protection and maintenance of electric hoists during use, any operational anomalies should be promptly recorded, including various parameters during the hoist's operation, followed by technical analysis to ensure the rated load is below the load requirements during debugging. At the same time, attention must be given to the cleanliness of the lubricating oil, ensuring it is free of impurities and the quantity is moderate during the hoist's operation.
In summary, enhancing and standardizing the protection and maintenance procedures for electric hoists is highly necessary. Prior to use, it is crucial to conduct scientific adjustment operations. During inspections, focus should be placed on the repair and maintenance of the brakes and reducers. By doing so consistently, the service life of the electric hoist can be significantly extended, and its power can be improved.
