What Will Chain Inspection and Proper Maintenance Do For Your Lift Truck Fleet?

Determine Chain Condition Promote Maximum Service Life of Chain

Determine Chain Condition

Elongation Rust Corrosion Cracked Plates Protruding Pins Misalignment Chain Anchor and Sheave Wear or Damage

Elongation

Chain elongated 3% or more should be replaced

This lengthening of the chain could reduce its strength by as much as 18%

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

Rust Corrosion

May cause side plate cracking and reduced load carrying capacity

Chains must always be completely protected by a film of lubricant

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

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

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

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

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

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
