8. Check to see that crane Operation Manual is with the
unit. If the manual is missing, obtain the serial number of
the unit and order an operation manual immediately.
Monthly Inspections
Check the following items:
1. All cylinders and valves for signs of leaks.
2. Lubrication as specified by the Lubrication Chart.
3. Load hook for cracks or having more than 15 percent
normal throat opening or 10 degree twist.
4. All structural members (boom, sub-base, turret and
outriggers) for bends, cracks, or broken members.
5. All welds for breaks or cracks.
6. All pins for proper installation.
7. All control, safety, and capacity placards for readability
and secure attachment.
8. Torque of cable clip bolts above wedge socket at end of
loadline should be 95 ft-lb.
9. All boom wear pad retaining bolts.
10. Boom extension cables for proper tension or evidence of
abnormal wear.
11. Sheaves and cable drums for wear and cracks.
12. Unspool loadline and check according to cable
maintenance procedure.
Periodic Inspection
Check the following items:
1. All items listed under daily, weekly, and monthly
inspections.
2. Loose bolts and fasteners in all areas. Torque pin
retainer bolts.
3. All pins, bearings, shafts, and gears for wear cracks or
distortion to include all pivot, outriggers and sheave
pins, and bearings.
4. Boom angle and boom length indicator for accuracy over
full range.
5. Hydraulic systems for proper operating pressure.
6. Lift and outrigger cylinders for drift caused by leaking
around piston.
7. Cylinders for:
a. Damaged rods
b. Dented barrels
c. Drift from oil leaking by piston
d. Leaks at rod seals, welds, or holding valves.
8. PTO drive line system for proper alignment, lubrication
and tightness.
9. Hydraulic hose and tubing for evidence of damage such
as blistering, crushing, or abrasion.
10. Top and bottom wear pads for excessive wear.
11. Inspect all electrical wires and connections for worn, cut
or deteriorated insulation and bare wire. Replace or
repair wires as required.
12. Extend and retract cables, sheaves, pins, and bearings
for wear or abrasion.
13. Main frame and stabilizer mount bolts for proper torque
(see Torque Chart).
14. Rotation bearing and gearbox mounting bolts for proper
torque (see Torque Chart).
Special Boom Inspection
If the boom has not been disassembled and inspected in the
last five years or 3,000 hours of use, the boom is to be
completely torn down to allow a thorough inspection of the
extend and retract cables, sheaves, and pins.
Stability
Stability of unit throughout working area. Check the stability
procedure in Installation Section of the Service Manual
annually or when any changes are made to crane or truck.
HOIST CABLE INSPECTION AND
MAINTENANCE
Inspection
All hoist cable in service needs to be inspected on a daily,
monthly, and quarterly basis. Cable which has been idle for a
period of a month or more must be given a thorough
inspection before it is placed in service. This inspection
should cover all types of deterioration including:
• Distortion such as kinking, crushing, un-stranding, bird
caging, main strand displacement or core protrusion.
• Loss of cable diameter in a short cable length or
unevenness of outer strands indicates the cable needs
to be replaced.
• General corrosion.
• Broken or cut strands.
• Number, distribution and type of visible broken wires.
• Core failure in rotation resistant ropes.
Only inspect the outer surface of a cable. Never attempt to
open the cable.
