CRANE INSPECTION AND MAINTENANCE 

Regularly scheduled inspection and maintenance intervals
are required to keep the unit in peak operating condition. The
following pages outline the inspection and maintenance
intervals.

Refer to the 

Service Manual

 for complete instructions on

performing maintenance on this crane.

Inspections

The inspection intervals listed below are to be conducted on
the unit to ensure safe and proper operation. If replacing a
missing fastener or tightening a loose fastener, refer to the
applicable torque chart in Section 1 of the Service Manual.
Should a deficiency 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  —  performed  by  the  operator  at  the
start of the day.

•

Weekly inspections — performed by the operator. 

•

Monthly  inspections  —  performed  by  maintenance
personnel.

•

Periodic  inspections  —  performed  by  maintenance
personnel at least every three months and includes all
i t e m s   l i s t e d   u n d e r   d a i l y,   w e e k l y,   a n d   m o n t h l y
inspections. Federal Laws through OSHA and ASME
B30.5 require that dated and signed records of these
periodic inspections be kept. An inspection log book is
available from National Crane.

DANGER

Do not, under any circumstances, work at an elevated
height without using proper fall protection as required by
local, state or federal regulations

!

 WARNING

If any deficiency determined during the inspection is a
safety hazard the machine must be removed from service
and the deficiency corrected.
