Situations in which electric chain hoists cannot lift

Electric chain hoist is also called chain-type electric hoist. When lifting operations, special attention should be paid to operation. It is forbidden to lift heavy objects when the hoist cannot be lifted. The following are several situations where the electric chain hoist cannot be lifted.

1. The lifting weight and lifting height are clearly indicated on the nameplate of the chain hoist, and it must not be overloaded, which is very prone to safety hazards. If the weight of the cargo is unknown, you should not lift it blindly. Try to use an electric chain hoist larger than the cargo tonnage for lifting.
2. When the site is too dark or in low visibility weather conditions, the operator cannot see the meeting signal, please do not carry out lifting work. If necessary, various protective measures must be taken.
3. In the process of lifting heavy objects, the chain hoist must not be lifted diagonally.
4. If the lifting goods have edges and corners, be sure to look for the central lifting point, and protect those corners and corners to avoid injury.
5. Containers containing dangerous liquids or gases, when heavy objects are full of liquids, can not be lifted casually. When lifting dangerous gas containers, the permission of professionals must be obtained.
6. In addition, if the cargo is difficult to find the lifting point, it is round or relatively large, it needs to be lifted with the help of slings. Do not lift it reluctantly, so as to avoid accidents caused by the unstable center of gravity of the cargo in the air.
