Precautions
for care & safe Use
* Determine
weight of the load.
* Rated capacity of a wire rope sling is
based upon the nominal or catalog
strength of the wire rope and factors affecting the overall
strength.
These factors include type of hitch, number of rope parts in the
sling
body, diameter around which the sling is bent, and diameter of the
pin or hook over which the sling eye is placed.
*
Never force the eye of a sling onto a hook
or pin that has a diameter
larger than the
natural width of the eye. Also avoid placing
a sling eye
onto a hook or pin whose
diameter is less than the diameter of the
sling
body.
*
Rated capacities of fittings and attachments
must be equal to or
greater than that of the
wire rope sling.
*
Never "shock load" a sling. The actual force
caused by a sudden
application of load can
easily exceed rated capacities and damage
a
sling. Abruptly releasing a load can also
damage the sling.
*
Protect the sling body against sharp edges
and corners of loads,
protrusions or
abrasive surfaces. Sharp bends can distort
wire rope and
reduce its strength.
*
Fiber core wire rope slings should never be
exposed to temperatures
exceeding 200
degrees F. Avoid using IWRC wire rope slings
at temperatures above 400 degrees F or below
-60 degrees F.
*
Slings are susceptible to damage and
strength loss when used in
chemically active
environments.
*
Slings fabricated with a hand tucked splice
can unravel and fail if the
sling is allowed
to rotate during use.
*
Do not drag slings across floors or pull
from underneath loads.
*
Avoid twists, kinks and knots before
lifting.
*
Store wire rope slings where they will not
be subjected to dirt, moisture,
extreme
heat, corrosion or mechanical damage. |
