The lifting chain of the hand-operated hoist plays a huge role in the lifting process, as it is directly connected to the heavy object and has a direct impact on the safety of the operation.

The lifting chain is used to lift equipment of different weights according to different specifications. Generally, a lifting chain with a diameter of 6mm is used to lift heavy objects up to 2 tons; Use 8mm diameter lifting chains to lift heavy objects ranging from 3 to 5 tons; Use a lifting chain with a diameter of 10mm for lifting over 5 tons.

When carrying out lifting operations, we must choose different specifications of chains based on the weight of the object. If the chain is too thin, the weight of the object to be lifted will be too large, which will make the chain unable to withstand gravity and pose a risk of breakage.

In the maintenance process of the chain, we should be more careful and patient. Before use, it is necessary to inspect the chain for cracks, degree of wear, severe corrosion, and a series of other tests. The safe operation of the lifting chain can only be ensured after it has been inspected and found to be intact.

After completing the homework, do not throw the lifting chain randomly. The chain itself is heavy and can easily cause damage to the ground or other equipment, as well as the chain itself, during the throwing process. This also exacerbates the degree of damage to the chain.

The storage of the chain is also crucial. After using the hand-operated hoist, the chain should be stored in a dry and ventilated place as much as possible, avoiding the erosion of the chain by rainy weather, thereby reducing the possibility of rusting.
