Length Tolerances (Single Part Wire Rope Slings): Standard length tolerance is plus or minus two rope diameters,
OR plus or minus 0.5% of the sling length, whichever is greater. The legs of bridle slings, or matched slings are
normally held to within one rope diameter.
Other fittings and latches are available upon request.
 ¹Minimum length based on thimbled eye and eye hook.
* 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 the effect of Angle chart below..

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.

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
