Chain Cleaning and Visual Inspection

Examine chain visually for defects

Chain Wear and Elongation Check

Slacken chain and check bearing surfaces between links for wear

Measure and record length of unworn section of chain using vernier caliper

Measure and record length of worn section of chain using vernier caliper

Calculate and record the amount of wear by subtracting unworn measurement from worn measurement

Is the amount of wear greater than the allowable chain wear?

Is the hook opened beyond the dimension given in Figure 5-3?

Lubricate hook swivels and pivot points if necessary

Replace hook if opened beyond specified dimensions

Sprocket and Bearings Inspection

Check sprocket and bearings in lower block

Lubricate sprocket and bearings if necessary

Replace damaged sprocket or bearings

Gather necessary materials: Bar and chain Oil (LUBRIPLATE or equal), oil solvent, penetrating oil, and graphite.

Ensure the hoist is not in operation and is safely secured.

Clean the chain with an oil solvent.

Lubricate the chain by coating it lightly with penetrating oil and graphite.

Ensure lubricant coats wear surfaces between links.

Is the chain operating under hot and dirty conditions?

Lubrication of Control Shaft, Brake Cam, and Valve Shifter

Apply a few drops of S.A.E. 60 oil on control shaft at bearing points.

Apply graphite grease on valve shifter and on brake cam.

Inspection and Maintenance Frequency

Describe the type of hoisting service the hoist is subjected to.

Does the lubrication frequency coincide with preventive maintenance inspections?

Check if all lubrication points are properly lubricated.

Is the hoist operating smoothly after lubrication?

Inspect Chain Anchor Connections

Ensure chain anchor connections are secure and intact

Verify anchor screw or pin is secure and not bent or broken

Confirm chain is solidly anchored

Check hoist brake for proper adjustment and operation

Ensure hooks are not bent or distorted

Verify hooks are not opened beyond correct opening sizes

Check hook latches for bends or damage
