Remark:
1. To ensure smooth running of the chain over the pocket wheels without any unusual impact, both the driven and idle pocket wheels shall be designed to suit the hoist chain.
2. The chain shall be guided smoothly and without twist into and out of the pocket wheels.
3. To avoid deformation of the last link of the chain, the chain-connecting parts of the hoist shall be designed so as to permit at least 5 % free movement relative to the inside width of the chain link.
4. Hoist chain shall not be used in the manufacture of slings, and the chain in a hoist shall not be used in a basket or choke hitch.
5. Should be used within the specified temperature range.
6. Hoist chain should not be used either immersed in acid solutions or exposed to acid fumes.
7. Hoist chain should not be galvanized or subjected to any plating processes without the approval of the manufacturer.
8. The chain shall not be allowed to pick up dirt, etc., which would impair its free movement.
9. In order to attain maximum service life of hoist chain, adequate lubrication, particularly in the interlink contact areas, is necessary.
