The chain block is not a fully enclosed structure, so we usually can see some of its internal components on the side of the chain block. At the same time, this structural feature can also be used to adjust the occurrence of chain jumping, ensuring the normal operation of the chain block without disassembling it.

The structural feature of the chain hoist also has certain drawbacks, that is, its ability to prevent rust and impurities is relatively weak. Because these parts are not protected by a casing, they are more prone to corrosion and rust in harsh environments, and once corroded and rusted, it is difficult to handle, seriously affecting the normal operation of the chain hoist.

The advice given by Crown Airlines regarding this is to keep the chain hoist in a clean, dry, and well ventilated environment while using it. If the environmental conditions do not allow it, we can choose to use plastic bags to cover it to avoid foreign objects from invading at all times.
