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 operation, and it can only be used normally after a series of standard unloaded 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 or replacements in case of damage, should be conducted.
The maintenance of electric hoists is divided into maintenance during installation and maintenance during operation after installation. Whether newly installed or disassembled, electric hoists must undergo a no-load operation to ensure normal operation. Power-on operations are not permitted before installation and debugging; only after completion of the debugging can the hoist be powered for a no-load test. Regarding the protective maintenance of electric hoists in use, if any operational anomalies are detected, it is crucial to promptly record the various values during the hoist's operation and conduct a technical analysis to ensure that the rated load is below the load required for debugging. At the same time, attention must be given to the cleanliness of the lubricating oil, ensuring that the oil is clean and free of impurities during the hoist's operation, and that the oil level is moderate.
In summary, enhancing and standardizing the protection and maintenance procedures for electric hoists is highly necessary. It is imperative to conduct scientific adjustment operations before using the electric hoist, and during inspections, pay close attention to the repair and maintenance of the brakes and reducers. By doing so consistently, the service life can be significantly extended, and power can be improved.
