RECORD OF SATISFACTORY CONDITION
Before putting the crane into service, describe the appearance and functions of the crane in writing.
Include observations about each part of the crane. Photograph the unit from multiple angles. Include
close range photographs of pivot points and pins, the hydraulic system (cylinder, modular power unit,
hose(s), and oil tank), hooks, shackles and shackle pins, casters, and caster brakes. Use the crane to lift
a test weight. Raise and lower the boom. Include notes about sounds heard while the power unit
operates and the cylinder extends and retracts (boom elevates and lowers, respectively). Thoroughly
photograph the unit and all labels applied to it. Collect all writings and photographs in a file. This file is a
record of the crane in
satisfactory condition
. Create a corresponding
RECORD
for the modular power
INSPECTIONS & MAINTENANCE
WARNING
Lower the boom and unload the crane BEFORE beginning maintenance/repairs. Apply both caster
brakes. Only qualified, authorized personnel trained to maintain hydraulic components should attempt
troubleshooting and repair of this equipment.
Inspections and repairs should only be performed by qualified persons. Compare the results of each
. Do not use the crane unless all parts are in
satisfactory condition. Replace parts that are not in satisfactory condition before returning the unit to
service.
Never make temporary repairs of damaged or missing parts
. Only use manufacturer-approved
replacement parts to restore the unit to satisfactory condition.
DON’T GUESS!
If you have any questions
about the condition of your lifter, contact the
department.
The phone number is
provided on the cover page of this manual. Apply all relevant inspections as instructed in the
(A)
Before each use, inspect the following items:
AIR PURGING PROCEDURE
The cylinder is designed to automatically purge air. If
sponginess is observed when the cylinder is extended, unload the
crane and cycle the cylinder a few times, i.e. fully extend the
cylinder and then completely retract it.
The cylinder includes an integral velocity fuse. The purpose of
the fuse is to prevent the cylinder from retracting too rapidly in the
event of a sudden loss of hydraulic pressure. A sudden loss of
pressure could result if, for example, a hose is punctured. If the
cylinder will not retract and the hydraulic system is intact (no
leaks, punctures, etc.) the velocity fuse is probably closed.
BOOM LENGTH ADJUSTMENT
To adjust the length of the boom, raise the boom until it is level. Remove the hitch pin and flat
washer and then pull out the clevis pin. The inner boom is now unfastened from the outer boom. Align
the appropriate holes in the inner and outer booms to achieve the necessary boom configuration
and then re-pin them.
