Instructions for Periodic Inspection
a
VISUALLY INSPECT the unit and all other equipment.
• Disassembly may be required in order to properly inspect individual
components. Contact factory for assembly/disassembly instructions.
Disassembly of the gearbox before contacting Thern, Inc. voids all
warranties.
• Check the finish for wear, flaking, or other damage.
• Check all equipment for cracks, dents, bending, rust, wear, corrosion and
other damage. If the equipment was overloaded, or if you notice cracks
and other signs of overloading and damage, promptly remove equipment
from use and have it repaired or replaced.
DO NOT CONTINUE TO USE
DAMAGED OR OVERLOADED EQUIPMENT OR SYNTHETIC
FIBER ROPE.
• Check all fasteners for stripped threads, wear, bends, and other damage.
• Check the gearbox for signs of leakage. Contact the factory if there are
any signs of lubricant leaking from the gearbox.
• Make sure the breather plug is clean, open and installed correctly.
• Make sure gear reducer is properly lubricated.
• Make sure all labels and plates are readable, firmly attached, free of
damage and clean. Replacements are available from the factory.
b
DRAIN A SMALL AMOUNT OF LUBRICANT from the reducer into a
clean container.
• Check the lubricant for dirt, metal particles, water, and other signs of
contamination. Completely drain the reducer if lubricant is contaminated.
c
INSPECT ROPE. Refer to rope manufacturer's guidelines for inspection.
d
MOVE THE DRUM with your hands.
• Check for excessive movement indicating worn or loose gears or
bearings. Excessive movement is caused by overloading or overheating,
and is a sign that your application may require a larger power unit.
• Disassemble the unit if necessary. Inspect keys, bearings, seals,
and shafts for wear, distortion, and other damage.
e
INSPECT FOUNDATION AND RIGGING.
• Check mounting fasteners for stripped threads, wear, and other damage.
• Check the foundation for cracks, corrosion, and other damage.
Perform periodic inspections:
• Every 12 months.
• Whenever you return the unit to
service from storage.
• Whenever you notice damage
or poor operation in a frequent
inspection.
• Whenever you have, or think you
may have, overloaded or shock
loaded the unit.
Frequent Rope Inspection:

Use Cordage Institute Interna-
tional Guidelines CI2001-04 as
a guideline for rope inspection,
replacement and maintenance.
