CRANE INSPECTION AND MAINTENANCE
A regular schedule of inspection and maintenance is
essential to keep your unit in peak operating efficiency.
Operators or service personnel responsible for the care of
the unit must be completely familiar with the type and
frequency of inspections and maintenance operations. The
following pages outline the inspections and maintenance
required to keep the crane in proper operating condition.
Refer to the Service Manual for complete instructions on
performing maintenance on this crane.
Inspection
The following pages list inspections which are to be
conducted on your unit to help assure its operating properly
and safely. Check all items listed at the frequency listed and
make necessary repairs prior to operating. Use applicable
torque table requirements for missing or loose fasteners.
Should a defect be found, a determination must be made as
to whether the deficiency is a safety hazard or though not yet
a safety hazard, needs to be monitored in the monthly
inspections.
The inspections are separated into the following frequency
classifications:
• Daily inspections -These items should be visually
inspected each day by the operator prior to using
the unit.
• Weekly inspections -These items should be visually
inspected weekly by the operator.
• Monthly inspections -These inspections are to be
performed monthly by the personnel responsible for
maintenance and service of the crane.
• Periodic inspections -This inspection is a thorough
inspection conducted at least every three months
and includes all items listed under Daily, Weekly,
and Monthly inspection in addition to those items
listed under periodic inspection. Federal Laws
