FREQUENT INSPECTION
Frequent inspections are to be performed by a qualified designated
person. Inspection intervals vary by class of service, for Class C
Service cranes they are to be performed monthly at a minimum.
Hooks and wire rope or load chain are to be inspected in monthly
intervals as a minimum and recorded including date, serial/trace
numbers and a signature. Frequent inspections also include a
thorough operational inspection. Items to be inspected include limit
switches, lubrication levels in all gearcases, wheels, bearings, etc.,
brakes, electrical equipment and all safety devices. Crane is to be
operated without a load to check for any unusual sounds, vibrations,
or anything that may be apparently wrong. The designated person
shall determine if conditions found are a hazard and a more detailed
inspection is necessary. Refer to the typical Inspection Schedule and
Maintenance Report in this manual.
NOTICE
CRANES THAT HAVE BEEN SITTING IDLE FOR A PERIOD
BETWEEN ONE TO SIX MONTHS SHALL RECEIVE THE
FREQUENT INSPECTION PRIOR TO ITS USE.
NEVER LEAVE AN UNATTENDED LOAD HANGING FROM THE
CRANE. LOAD MUST BE SAFELY PLACED ON FLOOR PRIOR
TO THE CRANE OPERATOR
LEAVING THE CONTROLS.
When crane is not in use, during the work period, it should be
parked in a safe location, such as the end of the bay or a location
that will not interfere with the movement of people, materials and
equipment. Turn power off to the mainline contactor of the crane.
Store the pendant against a wall or column to prevent damage from
traffic. At the end of the work period or day, park crane as described
herein and turn power off at both disconnects.
RESPONSIBILITY FOR SAFE OPERATION
Each crane operator should be held directly responsible for the safe
operation of his crane. The crane operator should STOP the crane
and refuse to handle loads when:
1. there is any doubt as to SAFETY.
2. any unusual vibrations or sounds are noticed before
or when starting the lift or traverse motions.
3. there are arguments or disagreements with the
floor man or hitchers.
4. the operator feels ill or is not alert.
INSPECTION
Overhead cranes are subject to four levels of inspection; Initial,
Pre-Shift, Frequent and Periodical in accordance with the latest
editions of ANSI/ASME B30.2 and CMAA 78. These inspections are
necessary to ensure the equipment is safe for use and operating at
its required performance level. Inspection criteria described herein
are general requirements. Specific inspection criteria will be based
on the options and accessories provided with your crane. Refer to
the manufacturer’s maintenance manual for the hoist/trolley and its
specific inspection criteria.
INITIAL INSPECTION
New, re-installed, altered, repaired and modified cranes shall be
inspected prior to initial use. Inspection of all altered, repaired or
modified cranes may be limited to the provisions affected by the
work as determined by a qualified crane technician. Inspections shall
include, but not limited to, clearances, operating speeds, lubrication,
control settings, safety devices, etc. Refer to START UP and PRE-
OPERATIONAL INSPECTION elsewhere in this manual.
PRE-SHIFT INSPECTION
A pre-shift inspection shall be performed by the crane operator or
designated person at the beginning of each shift, or the first time
the crane is used during each shift. This is a visual and operational
inspection to ensure the equipment is in good working order. Items
to be checked include limit switches, brakes, electrical equipment
and all safety devices. Crane is to be operated without a load to
check for any unusual sounds, vibrations, or anything that may be
apparently wrong. Any discrepancies or suspected discrepancies
shall be immediately reported to crane operator’s supervisor. Below
is a check list which can be used for this inspection.
