Chain Inspection
1. Test the hoist under load condition to make sure chain moves smoothly through the pockets
and chain guides.
2. Make sure that the chain is clean and properly lubricated.
3. Check for gouges, nicks, weld spatter, corrosion, chemical attack and distorted links. Replace
chain if it has been weakened. Ifchain appears to be stretched, measure according to the
chart below. Ifit measures greater than the Maximum 'A' dimension, replace the chain.
Be sure to measure that section of load chain that goes through the pocket wheel and chain
guide of idler wheels in the case of multifallhoists.
