Chain Inspection
Inspect chain before each use. Between regular inspections visually check on a daily basis the following:
• Clean chain before inspection using a non-caustic/non-acid solvent
• Lubrication of the chain may be necessary if it binds up or is noisy
• Chain feeds smoothly into and from the hoist and does not emit cracking noise when hoisting a load
• Visually examine link by link for any nicks, gouges, weld splatter, corrosion, or distorted links pay close
attention to chain's contact points, which may show excessive wear.
• Test hoist with load and observe operation of chain over load sheaves.
