Chain Wear Gauge
FORKLIFT CHAIN INSPECTION
After every 250 hours of truck
operation, lift chains should be inspected and lubricated.
Inspect for the following chain conditions:
1. Wear - A chain wear scale is available from PREMIER Parts. (SEE BELOW)
2. Rust and Corrosion
3. Cracked Plates
4. Ultimate Strength Failure
5. Tight Joints
6. Protruding or Turned Pins
7. Chain Side Wear
8. Chain Anchors and Sheaves
CHAIN WEAR SCALE INSTRUCTIONS
Scale has instructions printed on
the sides for use in determining chain “stretch”.
a. Determine pitch length of chain using 6" scale on one side of wear scale.
b. If pitch is 1/2, 3/4, 1, 1 1/2, 2 or 3 inches, use side A of scale.
c. If pitch is 5/8, 1 1/4, or 2 1/2 inches, use side B.
d. Align point A or B to center of a pin and note position of the opposite A or B point.
e. If the second point also lines up with a pin, the chain is worn and should be replaced. If the second point extends beyond, the chain is still in good condition as far as stretching is concerned.
