If you are not careful when using a chain hoist, it is easy to collide with a sharp object and the surface of the casing, causing the chain hoist to sag. The groove of the shell 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 handle groove of the chain hoist accessory squeezes the internal space, which makes the working space in the casing smaller and affects its normal operation. When the hoist is severely hit, it may also damage internal components. This is very serious and we should try to avoid it;
The grooves in the housing can also cause problems with the lifting chain. The groove of the shell reduces the running space of the lifting chain, so when we lift the chain crane 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 chain hoist unsightly, but also speeds up the scrapping and seriously reduces the protection of the casing. The performance of the embedded shell is greatly reduced and it is easy to rust, so we should repair it immediately after the shell is sunken.
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 has a certain corrosive effect on metals. Chain hoists are made of metal materials. So it's okay for chain hoists. After all, the surface of the part is protected by a layer of anti-rust paint. For a crane with a broken surface, the consequences are serious, and corrosive substances directly contact the built-in metal to form it. Some corrosive effects extend indefinitely for a long time, and chain hoists are likely to be discarded.
From a dynamic perspective, the visibility of severely polluted weather is extremely low, that is, only when you enter the hoist to see the operation, if someone misunderstands the operating environment, an accident is likely to occur. Caused by a heavy trip. Protective measures must be placed outside the work space and warning signs must be provided 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 visibility is low, construction is not recommended.
