Product Details
1. Loss of rated lifting capacity
Electric hoists are often used for years and months. Due to fatigue, wear and other damages, they have lost the ability to lift the rated lifting capacity. Even after repair, they still cannot reach the rated lifting capacity or have no repair value. If it is not allowed to use them with reduced tonnage, they should be scrapped and discontinued.
2. Excessive brake slip
When the sliding amount of the electric hoist during braking exceeds the specified value by a large margin, and after repair, the specified sliding amount cannot be guaranteed or there is no repair value, it should be scrapped and stopped from use.
3. Severe permanent deformation
When the main load-bearing components of an electric hoist suffer permanent deformation due to fatigue damage or overloading during long-term use, which seriously affects the basic performance of the electric hoist and loses its repair value, they should be scrapped and stopped from use.
4. There are visible cracks or potential crack hazards
When the main load-bearing components of the electric hoist have visible cracks or potential crack hazards detected, and cracks still appear after partial repair and replacement after a period of use, or there is a potential risk of cracks, they should be scrapped and stopped from use.
5. Severe corrosion
When operating an electric hoist in a corrosive environment, serious corrosion defects or significant reduction in thickness and size of the main load-bearing parts of the electric hoist due to corrosion should be scrapped and discontinued.
6. Abnormal impact vibration
When an electric hoist experiences abnormal vibration and impact during operation due to wear, fatigue, and deformation, and after repair, the abnormal vibration and impact cannot be avoided, it should be scrapped and stopped from use.
7. Excessive and abnormal noise exceeding the standard
Electric hoists, due to wear, fatigue, and deformation, may produce abnormal sounds or excessive noise levels. Even after repair, it cannot be guaranteed to be within the specified noise limit. If there are still abnormal sounds, they should be scrapped and stopped from use.
