Maintain written records of periodic inspections to provide an accumulative basis
for continuing evaluation. Inspect all items listed in the ‘Frequent Inspection’ section
of the Product Information Manual. Also inspect the following at the suggested
intervals recommended in Table 3 ‘Maintenance Interval Chart’ on page 3:
1.
Base, Frame and Motor Mounting Bracket. Check for deformed, cracked or
corroded main components. Replace damaged parts.
2.
Fasteners. Check retainer rings, capscrews, nuts and other fasteners on winch,
including mounting bolts. Replace if missing or damaged and tighten if loose.
3.
Drum and Sheaves. Check for cracks, wear or damage. Replace if necessary.
4.
Wire Rope. In addition to ‘Frequent Inspection’ requirements, also inspect for
the following:
a. Build-up of dirt and corrosion. Clean with steam or a stiff wire brush to
remove dirt and corrosion if necessary. Lubricate after cleaning.
b. Loose or damaged end connection. Replace if loose or damaged.
c. Check wire rope anchor is secure in drum.
d. Verify wire rope diameter. Measure the diameter of the wire rope from
crown-to-crown throughout the life of the wire rope. Recording of the actual
diameter should only be done with the wire rope under equivalent loading
and in the same operating section as accomplished during previous
inspections. If the actual diameter of the wire rope has decreased more than
1/64 inch (0.4 mm) a thorough examination of the wire rope should be
conducted by an experienced inspector to determine the suitability of the
wire rope to remain in service. Refer to Dwg. MHP0056 on page 2, A. Wire;
B. Crown to Crown; C. Strand; D. One Lay.
5.
All Components. Inspect for wear, damage, distortion, deformation and
cleanliness. If external evidence indicates damage, disassemble as required to
conduct a detailed inspection. Inspect gears, shafts, bearings, sheaves, springs
and covers. Replace worn or damaged parts. Clean, lubricate and reassemble.
6.
Brake. Test brake to ensure proper operation. Brake must hold a 125% rated
load at mid drum without slipping. If indicated by poor operation or visual
damage, disassemble and repair brake. Check all brake surfaces for wear,
deformation or foreign deposits. Clean and replace components as necessary.
Adjustments can be made to the band brake to compensate for normal brake
lining wear. Refer to ‘Adjusting Manual Brake’ on page 6. If brake band cannot
be adjusted to hold rated load, replace the brake band assembly.
7.
Foundation or Supporting Structure. Check for distortion, wear and continued
ability to support winch and rated load. Ensure winch is firmly mounted and that
fasteners are in good condition and tight.
8.
Winch Guard (optional feature). Verify fasteners are tight and in good
condition. Ensure guard is in good condition and panels are correctly positioned.
9.
Emergency Stop Valve (optional feature). During winch operation verify the
emergency stop valve operation. Valve must stop winch operation quickly. Valve
must reset properly. Contact Ingersoll Rand for additional information.
10.
Labels and Tags. Check for presence and legibility of labels. Replace if damaged
or missing.

n
Records and Reports
Inspection records, listing all points requiring periodic inspection should be
maintained for all load bearing equipment. Written reports, based on severity of
service, should be made on the condition of critical parts as a method of
documenting periodic inspections. These reports should be dated, signed by the
person who performed the inspection, and kept on file where they are readily
available for review.
n
Maintenance Intervals
Refer to ‘Periodic Inspection’ on page 2 and Table 2 ‘Inspection Classifications’
on page 2 for maintenance interval guidance.
