START-UP AND PRE-OPERATIONAL
INSPECTION
After the crane has been installed on the runway and the crane,
hoist and trolley has been connected to electrical service but prior to
placing into service, as a minimum the following inspections should
be made by a qualified person.
1. Check the main collector system for proper adjustment to
maintain proper contact with conductors. Check along runway
for possible interference if power is supplied by a cable reel or
festooned cable.
LOCK MAIN RUNWAY DISCONNECT SWITCH IN OPEN
POSITION BEFORE ATTEMPTING TO ADJUST MAIN
COLLECTORS OR CONDUCTORS.
2. Check the cross and pushbutton festoon conductors for
adjustment, including cable loop depth, and tracking.
3. Check oil level in both drive gearcases and axle bearing grease
fittings (if provided) for proper lubrication. If lubrication is
required refer to the LUBRICATION SECTION of this manual.
4. Inspect crane to make certain that all bolted connections
and attachments are properly tightened and that all electrical
connections are secure.
5. Inspect and adjust the motor brake air gap. Refer to the
MAINTENANCE SECTION of this manual.
6. The hoist/trolley should be inspected as instructed in the hoist/
trolley manufacturers instruction manual. For a double girder
crane inspect the clearance between wheel flanges and the
girder rail per manufacturers requirements. If hoist is equipped
with adjustable limit switches, confirm settings meet the
applications requirements.
7. Inspect the alignment of the trolley end stops to the trolley.
8. Turn power on at both disconnects and mainline. Inspect hoist
for reverse phase condition by ensuring push button operation
corresponds to intended direction of travel and correct if
necessary per manufacturer’s instructions.
9. Operate the trolley to verify both motors operate in the same
direction.
10. With no load, operate hoist/trolley back and forth the full
length of girder. During the operation ensure and verify proper
clearances from obstructions per CMAA, ASME B30.2, ASME
B30.17 and OSHA requirements.
11. Load testing the crane should be performed in accordance
with ANSI/ASME B30.2, local, state and/or provincial codes
and regulations. A written report should be prepared during the
performance of this test and placed on file.

OPERATING RULES
Operating rules listed below are an earnest effort to encourage
SAFETY and are not intended to take precedence over individual
plant safety rules and regulations or rules set forth by various
applicable codes.
A good operator operates his crane as smoothly as possible and
knows and follows the suggested rules below for safe, efficient
crane handling.
OPERATING PRECAUTIONS
THESE TROLLEYS HOISTS ARE NOT DESIGNED NOR
INTENDED TO BE USED FOR SUPPORT OR TRANSPORT OF
PEOPLE OR FOR TRANSPORTING LOADS OVER PEOPLE.
Safe operation of an overhead hoist is the operator’s responsibility.
Listed below are some basic rules that can make an operator
aware of dangerous practices to avoid and precautions to take
for his own safety and the safety of others. Observance of these
rules in addition to frequent examinations and periodic inspection
of the equipment may save injury to personnel and damage to the
equipment.
DO Always center trolley over load when hoisting.
DO NOT stand and DO NOT cause or allow others to
stand or get under any load the trolley is supporting.
DO keep clear, and make sure others keep clear,
of any load the trolley is supporting.
DO NOT attempt to operate trolley before completing
tests and adjustments.
Improper and careless operation can result in a
hazardous condition for operator and load.
ALWAYS be sure load is clear of obstruction
before traversing load.
IF TROLLEY IS MOUNTED ON A RAIL, THEN END STOPS
MUST BE INSTALLED TO PREVENT TROLLEY FROM
RUNNING OFF THE END OF THE RAIL
RESULTING IN INJURY TO THE OPERATOR AND OTHERS
AND DAMAGES TO THE LOAD AND OTHER PROPERTY. END
STOPS FOR THE TROLLEY MUST ALSO BE INSTALLED.
Refer to hoist and trolley instruction manuals for
safety warnings on hoists and trolleys.
Read and comply with ANSI B30.2 or B30.17-latest edition.
Read and comply with all local, state and national safety codes.
MAKE SURE ALL INSTALLATION AND START-UP INSPECTION
HAVE BEEN MADE IN ACCORDANCE WITH INSTRUCTIONS
FURNISHED WITH THE HOIST AND TROLLEY BEFORE
TURNING ON THE POWER.
