Some netizens say that the explosion-proof chain hoists they use always shake when lifting heavy objects. Is this a normal phenomenon? How to avoid it if it is abnormal?
First of all, it is certain that slight shaking during the lifting of the explosion-proof chain hoist is normal. However, if the shaking angle is too large, it is abnormal. We need to eliminate them one by one from the following aspects.
1. When the explosion-proof chain hoist is overloaded, it will cause shaking because it cannot bear the load. Such shaking can easily cause the items to fall off and hurt others.
2. Inclined and crooked lifting can also cause heavy objects to shake during the lifting process, and crooked and crooked lifting is very dangerous, which will not only cause wear on hooks, lifting chains and other components, but also cause explosion-proof chain hoists in some cases. Overloaded.
3. Excessive jerk when pulling the chain will also cause greater swaying. During the lifting process, no matter the weight is rising or falling, when pulling the hand chain, the force should be even and gentle. Do not use too much force.
In addition, there is one point that is particularly easy to overlook is that the lifting point of the heavy object hanging by the explosion-proof chain hoist hook is not determined, which will also cause the tilt to shake greatly during lifting. We must stop and adjust the crane in time. point.
