Topic: How to solve the shaking problem of electric chain hoist?
Some customers experience cargo shaking during lifting operations using electric chain hoists and do not know how to solve this problem. The following is a detailed analysis of the reasons for the shaking of the electric chain hoist and the corresponding solutions. I hope it will be helpful to you.
Reasons for shaking of electric chain hoist:
1. The main reason for the shaking of the electric chain hoist is inertia, which usually occurs when the operation starts and stops.
2. If the amplitude of shaking depends on the magnitude of inertia, what determines the magnitude of inertia? It is determined by the size of the speed difference. For a fixed speed, it depends on the speed is fast and slow.
3. Under the same speed, the longer the drooping chain or rope, the greater the inertia and the greater the shaking amplitude.
4. When two electric chain hoists of the same model and specification, that is, when the rated load is the same, the lifting and speed are the same, and the lifting height is the same, when the same object is lifted separately, the electric hoist with the thinner lifting chain will shake more.
5. There is another situation that the electric chain hoist is improperly connected with the lifting object, that is, the lifting object is not tied or the center of gravity is not found.
Shaking solution of electric chain hoist
1. The lifting speed is kept at a constant speed. If the speed is single speed, a slow speed can be used. But considering the work efficiency, and don't want the speed to be too slow, then choose the frequency conversion.
2. Don't use thin chains when lifting. Double chains can be double chains. The greater the number of chains, the more stable. However, the speed is slower, and the more the number of chain links, the larger the volume of the electric chain hoist.
