8-12 Lift Truck Maintenance
Check for any loose parts or fittings. Check for leaks, any damaged
or loose rollers, and rail wear (metal flaking). Inspect all lift line
hydraulic connections for leaks
Load Backrest
Check the condition of the load backrest.
Inspect the welds on the load backrest and
carriage. Check that the mounting
fasteners are not missing and properly
tightened. If the load backrest has been
removed, make sure that fork stops have
been installed on each side of the carriage.
If the truck is not equipped with a load backrest, or it has
been removed, then fork stops must be installed on each
side of the carriage to prevent the forks from being
unintentionally forced off of the carriage during operation.
Lift Chain Maintenance
The chain system on the upright was designed for safe, efficient, and
reliable transmission of lifting force from hydraulic cylinder to the
forks. Safe use of your truck with minimum down-time depends on
the correct care and maintenance of the lift chains. Lift chains need
periodic maintenance to give maximum service life.
Do not attempt to repair a worn chain.
Lift Chain Inspection and Measurement
Inspect and lubricate the lift chains every PM (50-250 hours). When
operating in corrosive environments, inspect the chains every 50
hours. During the inspection, check for the following conditions:
• Corrosion, cracked plates, raised or turned pins, tight joints,
wear, and worn pins or holes.
• When the pins or holes become worn, the chain becomes
longer. When a section of chain is 3% longer than a section
of new chain, the chain is worn and must be discarded.
