INSPECTION
Frequent inspections should be performed on equipment in regular service. Refer
to Product Information Manual. Some options may not apply to your product, refer
to data (name) plate for correct model and any applicable manuals.
n
Periodic Inspection
Refer to Table 2 ‘Inspection Classifications’ on page 3 for suggested winch
inspection classifications for Periodic Inspection intervals. Select conditions most
appropriate to application.
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 4:
1.
Siderails and Uprights. 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.
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.

5.
All Components. Inspect for wear, damage, distortion, deformation, cracks, 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.
Brakes. Individually test brakes installed to ensure proper operation. Brakes
must hold a 125% rated load at mid drum without slipping. If indicated by poor
operation or visual damage, disassemble and repair brake(s). 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 ‘Adjustments ’ on page 7.
If band brake cannot be adjusted to hold rated load, replace the brake band
assembly. Adjustments cannot be made to the disc brake. The disc brake must
be repaired as described in “MAINTENANCE” on page 7.
WARNING
•
Replace band brakes that are worn or have metal to metal contact. Worn
or improperly functioning brakes may cause excessive heat build-up or
cause sparks.
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. Verify fasteners are tight and in good condition. Ensure guard is
in good condition and panels are correctly positioned.
9.
Limit Switches. Operate winch in both directions to activate limit switches. Limit
switches should engage (stop winch operation) at established settings (+/- 2
feet [+/- 0.6 metres]). Reset limit switch by operating winch in opposite direction.
Refer to ‘Limit Switch Adjustment’ procedure in Product Information Manual.
10.
Emergency Stop Valve. During winch operation verify the emergency stop
valve operation. Valve must stop winch operation quickly. Valve must reset
properly. Refer to ‘Emergency Stop Valve’ in the “OPERATION” section in Product
Information Manual for procedures.
11.
Overload Device. Ensure overload device is properly set to stop the winch when
loads exceed 150% (+/- 25%) of winch rated capacity. If winch does not shut
down, contact your distributor or the factory for repair information.
12.
Press Roller. Inspect rollers for wear and grooves. Ensure rollers freely rotate.
Replace rollers if worn or grooved. Replace bearings if rotation is rough or stiff.
13.
Labels and Tags. Check for presence and legibility of labels. Replace if damaged
or missing.
