** A quad branch chain sling, especially when used on a load of rigid structure, is usually not sustaining the load evenly distributed on
each of its four branches. The maximum working load limits are therefore set at the same values as for triple branch chain slings of equal
quality and size and used with branches at same angle of inclination.
Do not exceed rated capacities. Sling capacity decreases as the angle from horizontal decreases. Slings should
not be used at angles of less than 30º. Refer to chain chart above and Effect of Angle chart below.
Effect of Angle of Lift on a Sling's Rated Capacity
DEFINITION
as used throughout this catalog, serves to alert users to potentially hazardous situations which often occur
in the use of these products. Failure to read, understand and follow the accompanying instructions on how
to avoid these situations could result in death or serious injury.
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.
What would be the rating of each
sling rigged at this angle?		 chain slings What capacity sling do I need?
1. Determine the weight that the sling
   will be lifting [LW].
1. Calculate the Reduction Factor [RF].
2. Calculate the Tension Factor [TF].
a. Using the angle from horizontal,
     read across the Angle Chart to
     the corresponding number of the
    Reduction Factor column.

b. Divide sling height* [H] by sling
    length* [L].
b. Divide sling height* [L] by sling
   length* [H].
2. Reduction Factor [RF] x the sling's
   rated capacity for the type hitch that
   will be used = Sling's Reduced Rating
3. Lifting Weight [LW] x the Tension
   Factor [TF] = Minimum Sling
    Rating  for the type of hitch that
    will be used.

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:
Sling capacity decreases as the angle
from horizontal decreases. Sling angles
of less than 30° are not recommended.
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
Reduced sling rating in this
configuration = .667
(RF) x 6,000 lbs. = 4,000 lbs. of lifting
capacity per sling
