If you are not careful when using a chain hoist, it can easily collide with sharp objects and the surface of the casing, causing the chain hoist accessories to sag. The groove of the sleeve will cause us a lot of trouble, which will not only reduce the performance of the chain hoist, but also pose a threat to our safety.
The groove of the hoist accessory cover will squeeze the internal space, which will reduce the working space inside the housing and affect its normal work. When the hoist is severely hit, internal components may also be damaged. This is very serious and we should try to avoid it;
Grooves in the housing can also cause problems with hoist chains. The groove of the casing reduces the running space of the lifting chain, so when we lift the hoist by hand, if the chain is slightly inclined, a chain problem may occur, which will cause trouble to our work;
The groove of the casing not only makes the hoist unsightly, but also speeds up the scrapping and seriously reduces the protection of the casing. The performance of the recessed shell is greatly reduced and it is easy to rust, so we should repair it immediately after the shell is recessed.
From a static point of view, the pH value of severely polluted weather is acidic and contains a certain amount of water vapor, so it will have a certain corrosive effect on the metal, and the chain hoist is just made of metal materials. So for the hoist, it doesn't matter, after all, the surface of the component is protected by a rust-proof paint layer. For a crane with a damaged surface, the consequences are serious, and corrosive substances directly contact the built-in metal to form it. Certain corrosive effects can extend indefinitely for a long time, and the chain hoist is likely to be abandoned.
From a dynamic point of view, the visibility of heavily polluted weather is extremely low, that is, only when walking into a chain hoist to see the operation, if someone misunderstands the operating environment, the possibility of an accident is very high. Caused by a heavy trip. It is necessary to put protective measures outside the work space and set warning signs to avoid such accidents. In addition, the operator should reduce the operating speed. If the lifting distance is high, it is beyond the visible range. Use lighting to help improve visibility and avoid accidents. Of course, if the visibility is low, we do not recommend that you continue construction.
