CRANE INSPECTION AND MAINTENANCE
Regularly scheduled inspections and maintenance is
essential to keep your unit in peak operating efficiency. 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 inspection intervals listed below are to be conducted on
the unit to ensure safe and proper operation. Refer to the
Service Manual when installing 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 — are performed by the operator
before beginning the days work.
• Weekly inspections — are performed by the operator
weekly.
• Monthly inspections — are performed by maintenance
personnel monthly.
• Periodic inspections — performed by maintenance
personnel at least every three months and includes all
items listed under daily, weekly, and monthly
inspections. Federal Laws through OSHA and ANSI
B30.5 require that dated and signed records of these
periodic inspections be kept. An inspection log book is
available from your National Crane distributor or
Manitowoc Crane Care.

DANGER
