1. Chain Inspection & Maintenance TM

2. If Chains Are Not Carefully Inspected for Wear And Properly Maintained, Ultimately They Will Fail

3. What Will Chain Inspection and Proper Maintenance Do For Your Lift Truck Fleet? Determine Chain Condition Promote Maximum Service Life of Chain

4. Determine Chain Condition Elongation Rust Corrosion Cracked Plates Protruding Pins Misalignment Chain Anchor and Sheave Wear or Damage

5. Elongation Chain elongated 3% or more should be replaced This lengthening of the chain could reduce its strength by as much as 18%

6. Chain Wear Gauge This tool is used to measure the lengthening of chains When the points on the gauge appear at the center of the pin ends, the chain condition is acceptable If the points on the gauge appear opposite the center of the pin ends, the chain is worn out and should be replaced

7. Rust Corrosion May cause side plate cracking and reduced load carrying capacity Chains must always be completely protected by a film of lubricant

8. Cracked Plates Repeated heavy loads over a period of time may crack the plates and eventually break the chain The chains must be replaced if a crack is discovered

9. Protruding Pins Heavy loaded chains operating with little lubrication generate friction between the pin and plates Over time, pins will slowly work out of the chain causing chain failure

10. Misalignment Is determined by a wear pattern on pin heads and outside plates Will damage the chain and sheaves and cause internal friction in the chain

11. Chain Anchors and Sheaves Check chain anchors for wear, damage, and incorrect alignment Anchors with worn or broken fingers must be replaced Chain anchor pins and their retention should be checked and pins replaced as necessary

12. Promote Maximum Service Life Inadequate maintenance accounts for most complaints of unsatisfactory chain performance Each lift chain should be checked after every 8 hours of operation and inspected and lubricated after every 250 operating hours Do not try to repair worn sections or splice a new or used piece of chain Replace complete chain, if wear is indicated Replace lift chains in pairs

13. Why Replacement of Both Chains is Mandatory Older chain could sustain fatigue cracks Older chain has experienced stretch Chain anchor adjustments may not be sufficient for the new chain Chain wear will be uneven, thus accelerating wear on new chain New chain will have less rolling resistance
