What Will Chain Inspection andProper Maintenance Do For YourLift Truck Fleet?

Determine Chain Condition

Promote Maximum Service Life of Chain


4/22

Determine Chain Condition

Elongation

Rust Corrosion

Cracked Plates

Protruding Pins

Misalignment Chain Anchor and Sheave Wear or Damage


5/22

Elongation

Chain elongated 3% or more should be

replaced

This lengthening of the chain could reduce its

strength by as much as 18%


6/22

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 ofthe pin ends, the chain is

worn out and should be

replaced


7/22

Rust Corrosion

May cause side plate cracking and reduced

load carrying capacity Chains must always be completely protected

by a film oflubricant


8/22

Cracked Plates

Repeated heavy loads over a period of time

may crack the plates and eventually break thechain

The chains must be replaced if a crack is

discovered


9/22

Protruding Pins

Heavy loaded chains operating with little

lubrication generate friction between the pinand plates

Over time, pins will slowly work out of the chain

causing chain failure


10/22

Misalignment

Is determined by a wear pattern on pin headsand outside plates

Will damage the chain and sheaves and cause

internal friction in the chain


11/22

Chain Anchors and Sheaves

Check chain anchors for wear, damage, andincorrect alignment

Anchors with worn or broken fingers must be

replaced

Chain anchor pins and their retention should

be checked and pins replaced as necessary


12/22

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


13/22

Why Replacement of Both Chainsis 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
