3.
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.
(Dwg. MHP0056)
Pivot assemblies are pre-packed with grease at the factory and
should not require any additional lubrication.
If after time it becomes necessary to disassemble the pivot
assembly, all parts should be cleaned with a mineral spirit solution
and the bearings repacked with grease. Recommended lubricant
(10885) is available through Ingersoll-Rand.

and fittings for cuts, damage, or leakage. Repair or replace
tubing and fittings as necessary.
7.
SUPPORTING STRUCTURE. Check for distortion, wear
and continued ability to support load.
8.
CARRIAGE TROLLEYS. Check trolley assemblies for ease
of movement, loose or missing hardware. Check for cracks in
or damage to wheels. Repair or replace trolley and/or wheels
as necessary.
9.
LABELS AND TAGS. Check for presence and legibility of
labels. Replace if damaged or missing.

Units which have been idle for a period of one month or
more, but less than one year, should be given an inspection
conforming with the requirements of "Frequent Inspection"
prior to being placed into service.
2.
Units which have been idle for a period of more than one year
should be given an inspection conforming with the
requirements of "Periodic Inspection" prior to being placed
into service.
3.
Standby units should be inspected at least semiannually in
accordance with the requirements of "Frequent Inspection".
In abnormal operating conditions, units should be inspected
at shorter intervals.
Wire Rope
Follow wire rope manufacturer's instructions. At a minimum,
observe the following guidelines.
1.
Clean with a brush or steam to remove dirt, rock dust or other
foreign material on surface of wire rope.
• Do not use an acid-based solvent. Only use cleaning fluids
specified by wire rope manufacturer.
2.

(SAE 30W) oil as a wire rope lubricant.
3.
Brush, drip or spray lubricant weekly, or more frequently,
