4 Handling and Installation
RECEIVING, INSPECTION,
AND
STORAGE
For all wire rope, the best time to begin taking appropriate care and handling
measures is immediately upon receiving it.
On arrival, the rope should
be
care-
fully checked to make certain that the delivered product matches the description
on tags, requisition forms, packing slips, purchase order, and invoice.
After these necessary preliminary checks, the next concern is that
of
providing
weather-proof storage space.
If
wire rope is to be kept unused for a considerable
time, it must be protected from the elements. The ideal storage area is a dry,
well-ventilated building
or
shed. Avoid closed, unheated, tightly sealed buildings
or
enclosures because condensation will form when warm, moist outside (ambi-
ent) air envelops the colder rope. Although wire rope is protected by a lubricant,
this is not totally effective since condensation can still occur within the small
interstices between strands and wires, thereby causing corrosion problems.
On the other hand.
if
the delivery site conditions preclude storage in an inside
space and the rope must be kept outdoors,
it
should be covered with a waterproof
material. This covering will also prevent the lubricant from drying out.
Store the
reel on an elevated platform
or
pallet that will keep it from direct contact with
the ground.
Never store wire rope in areas subject to elevated temperatures. Dust and grit,
or chemically laden atmospheres should also be avoided. Although lubricant
applied during manufacturing offers initial protection, extended storage may
require additional field lubrication.
Whenever wire rope remains on an idle machine, coat the rope with an appro-
priate protective lubricant. This will provide additional protection against envi-
ronmental conditions.
If
the wire rope is inactive for an extended period while
wound on the drum
of
the idle equipment, it may be necessary to apply a coating
of
lubricant to each layer as the rope is wound on the drum. Cleaning, inspection
and re-Iubrication should precede start-up
of
the equipment.

ROPE
INSTALLATION
CHECKING
THE
DIAMETER
It
is important to check the diameter
of
the delivered rope before installation.
This is to make certain that the rope meets the specified nominal diameter for the
given application.
Imperial (inch) and metric (millimeter) ropes are not always interchangeable.
Consult the rope manufacturer for details on any specific rope diameter.
