Sixth – Operate traverse from one end of bridge to the
other, checking for obstructions or interferences. Proceed
with CAUTION and be prepared to stop short of any
obstructions. If traverse power is interrupted during traverse
travel, check traverse collectors for proper contact with
bridge conductors.
Lock main runway disconnect switch in open
(power off) position before attempting to adjust
cross collectors or conductors.
Seventh – After making certain that all building and
structural clearances are adequate, practice going “Left”
and “Right” with push button depressed. Note the stopping
distance of the trolley without load.
After becoming familiar with these motions, the operator
can now depress the hoist “Up” button.
If, when depressing hoist “Up” button, the hook
should lower – STOP AT ONCE – Do not attempt
to operate again. Report this condition to proper
supervisor for correction with instructions
furnished with your hoist manual.
Depress the “Down” button, with hook moving downward
on multi-speed hoists, try to feel the steps in relation to
speed increase as push button is depressed further.
Hook may be lowered until TWO FULL WRAPS of cable
remain on the drum. Note position of hook and NEVER
LOWER HOOK BELOW THIS POSITION. (Some hoists
may have a lower limit switch which will stop hoist when
this position is reached. Consult Hoist Manufacturer’s
Manual.)
Depress the hoist “Up” button and slowly return the hook
to near its high position. Continue to raise hook by slowly
inching. CAREFULLY OBSERVE the relationship of the
hook block and the bottom of the hoist frame. The hoist
upper limit switch, when working properly should cause
the hoist up motion to stop and/or reverse direction.
Do not contact or strike hoist frame with hook
block. If hoist motion is not interrupted by limit
switch, stop hoist by removing finger from
button and/or depressing the STOP button. Do
not attempt further operation until limit switch
is operable. Consult Hoist Manufacturer’s
Instructions.
Repeat upper limit switch test described above at full
speed.
The operator should locate the runway disconnect and
make sure this switch is locked open (POWER OFF). The
operator should now operate the various push buttons to
get the “feel” and determine that they do not bind or stick
in any position. The operator should become familiar with
push button location for their respective motions as well
as “start” and “stop” buttons which operate the crane main
line contactor. The main line contactor will shut off power
to all motions.
If any push button binds or sticks in any position
– Do not turn power on – Determine the cause
of malfunction and correct before operating
crane.
OPERATING THE CONTROLS (NO LOAD): Having
inspected and tried the pendant push button station, the
crane operator is now ready to try the crane under power.
First – Close the crane runway disconnect switch.
Second – Close the crane disconnect switch.
Third – Press the start-push button which will close the
main line contactor, applying power to all control devices.
The traverse is now ready for further testing.
The traverse is powered by a single or two speed motor.
There is one button for each direction, labeled “Left” and
“Right”. Depressing either button will cause traverse to
operate.
ALWAYS ALLOW TRAVERSE TO COME TO A
COMPLETE STOP BEFORE CHANGING
DIRECTION. ABRUPT CHANGE OF TRAVERSE
DIRECTION WHILE IN MOTION, MAY CAUSE
ADVERSE OPERATING CHARACTERISTICS OR
DAMAGE TO TRAVERSE AND DRIVE
COMPONENTS.
Fourth – Momentarily depress traverse “Left” button.
Check to be certain motor runs in the proper direction.
Momentarily depress “Right” button. Check direction. To
reverse directions, interchange leads L1 and L2 in the
traverse panel.
Lock crane main switch open (power off) before
reversing leads.
Fifth – To check that electrical connections have been
properly made, operate traverse cautiously on bridge.
Watch for any obstructions or interferences between
traverse and building parts. Depress “Left” button slightly
– traverse will travel along bridge.
