As is well known, a chain hoist is composed of dozens of mechanical components, each of which plays an important role in its operation. Today, Guanhang will mainly introduce the safety factor issues of the chain hoist itself and the lifting chain.

In fact, different components of a chain hoist have different load-bearing capacities. Generally speaking, the lifting chain part has a higher load capacity, especially for chain hoists that use G80 chains. The safety factor of this type of lifting chain can reach 4 times. That is to say, if the rated load of the chain is 4 tons, then this type of chain can withstand any weight up to 16 tons without any problem.

Although the lifting chain of a chain hoist has a high safety factor, the safety factor of the chain hoist itself is generally around 1.5, which means that a chain hoist with a rated load of 4 tons can operate safely under a load of less than 6 tons. Facing several different load capacities, Guanhang kindly reminds everyone to follow the minimum load standard for lifting, that is, to follow the safety factor of the chain hoist itself.

The reason is simple. If the lifting operation is carried out according to the strength standard of the lifting chain, the chain hoist itself will be severely damaged. However, if the lifting operation is carried out according to the strength standard of the chain hoist itself, the lifting chain will be intact. The overall strength standard of the chain hoist must be lower than that of all components, so the lifting operation must be carried out according to the rated load of the chain hoist.
