Chain electric hoist, also known as chain hoist, electric chain hoist, is mainly used in major factories, warehouses, wind power generation, logistics, docks, construction and other industries for lifting or loading and unloading goods. Its performance structure is advanced, small size, light weight, reliable performance, convenient operation, and wide application range. The operation contents of the chain electric hoist during operation are as follows:

6. The lifting chain should be hung vertically, and its inclination should be kept within the range of no more than 10°-15° between the chain and the plumb line. The double-row chain should not be turned over and twisted. When the diameter of the worn part of the chain is reduced by 10% of the original diameter, the chain should be replaced with a new one. The chain must be replaced when plastic elongation reaches 5% of the original length. The chain is severely rusted and should not be used.
7. It is strictly forbidden to abide by the lifting safety operating procedures, and it is strictly forbidden to lift flammable and explosive materials. This machine is not suitable for carrying people or lifting corrosive materials that may hurt people.
