EYE & EYE WIRE ROPE & SLINGS

TYPE IMP PERMALOC WIRE ROPE SLINGS
Our Permaloc Slings are made using the flemish splice technique to form the eyes. Unlike the simple return loop
method that places 100% of its strength on the swaged sleeve, Permaloc slings have reserve strength should the
sleeve become damaged in use.
eye and eye wire rope
Features and Benefits
Maintains all the basic wire rope sling features plus ...
Promotes Safety
Reserve strength - integrity of eyes not solely dependent
    upon steel sleeves
IWRC resists crushing better than FC ropes
Saves Money
When specified, thimble eyes protect wire rope from
   wear for increased life
Good abrasion resistance for longer life

Note: Larger diameter slings available. Basket ratings are based on a minimum D/d of 25.
¹ Minimum sling length when using standard eyes.
* Do not exceed rated capacities. Sling capacity decreases as the angle from horizontal decreases. Slings
should not be used at angles of less than 30°. Refer to Effect of Angle chart below.
Above rope prices are domestic, for imported rope call us.
Slings shorter than min. lengths listed may require reduced capacity ratings and/or eye lengths.
EFFECT OF SLING ANGLE
Using slings at an angle can become deadly if that angle is not taken into consideration when selecting the sling to
be used. The tension on each leg of the sling is increased as the angle of lift, from horizontal, decreases. It is most
desirable for a sling to have a larger angle of lift, approaching 90°. Lifts with angles of less than 30° from horizontal
are not recommended. If you can measure the angle of lift or the length and height of the sling as rigged, you can
determine the properly rated sling for your lift. The Increased Tension method provides the increased tension as a
function of the sling angle. Alternatively, the sling Reduced Capacity method may be used to determine reduced lift
capacity for any angle.
INCREASED TENSION
Determine capacity
of sling needed
 choker hitch
REDUCED CAPACITY
Calculate rating of each sling
rigged at this angle
1. Determine the load weight (LW). 1. Calculate the reduction factor (RF).
a. Using the angle from horizontal,
    read across the Angle Chart to
    the corresponding number of the
   Reduction Factor column.
2. Calculate the Tension Factor [TF].
a. Determine the sling angle as mea-
    sured from the horizontal, and the
    corresponding tension factor (TF)
    from the effect of angle chart.
-OR-
b. Divide sling height* (H) by sling
    length* (L).
-OR-
b. Length* (L) divided by height*
    (H)
2. Reduction factor (RF) x the sling’s
    rated capacity for the type hitch that
    will be used = sling’s reduced rating.
3. Determine the share of the load
    applied to each sling leg (LW).
4. Multiply (LW) by (TF) to determine
    the sling leg tension. The capacity of
    the selected sling or sling leg must
    meet the calculated tension value.		 *Measured from a common horizontal
plane to the hoisting hook.

Example:
Vertical Choker rating of each sling:
6,000 lbs.
Measured Length (L) = 6 ft.
Measured Height (H) = 4 ft.
Reduction Factor (RF) = 4 (H) ÷ 6 (L) = .667
Example:
Load weight = 1,000 lbs.
Rigging - 2 slings in vertical hitch
Lifting Weight (LW) per sling = 500 lbs.
Measured Length (L) = 10 ft.
Measured Height (H) = 5 ft.
Tension Factor (TF) = 10 (L) ÷ 5 (H) = 2.0
Minimum Vertical Rated Capacity required
for this lift = 500 (LW) x 2.0 (TF) = 1000 lbs.
per sling
Sling capacity decreases as the angle
from horizontal decreases. Sling angles
of less than 30° are not recommended.
Reduced sling rating in this configuration
= .667
(RF) x 6,000 lbs. = 4,000 lbs. of lifting
capacity per sling
