3.6 Inspection – conveyor chains
3.6.1 Conveyor chains
The most common types of conveyor chains are:
NB: When dealing with cleated chains special safety measures against
pinch and shear points must be considered.
3.6.1.1 Cleated, friction and wedge chains
Cleated chains, friction chains and wedge chains, or other special chains
should be inspected regularly, and any defective links replaced or cleaned.
Warning: Only warm water (50°C), with soap if necessary, may be used
for cleaning conveyor chains.
Check the guards on cleated chain conveyors.
3.6.2 Checking the tension of conveyor chain
The chain is made of elastic material. The chain eventually stretches as the
material creeps. The extent of the stretch depends on the traction force in

• Plain conveyor chains
2
• Chain with flexible cleats
for vertical wedge convey-
ors
3
• Chain with friction surface
for conveyors with an in-
cline up to 30°. The friction
surfaces are normally dis-
tributed over the chain at a
predetermined distance.
