liftalloy double chain slings

LiftAlloy Grade 80 chain slings are recommended for rugged
industrial applications in harsh environments where flexibility,
abrasion resistance and long life are required. OSHA required
annual inspections can be performed by our trained personnel.

NOTE: Proof Coil Grad 30, High Test Grade 40 and Grade
70 transport tiedown chain and their fittings are not
recommended for listing or hoisting per ASME B30.9.

NOTE: Also referred to as "Working Load Limit".
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 chain chart and Effect of Angle chart below.

Effect of Angle of Lift on a Sling's Rated Capacity
DEFINITION
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?

1. Determine the weight that the sling
    will be lifting [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. Using the angle from horizontal,
    read across the angle chart to the
    corresponding number of Tension
    Factor column.

b. Divide sling height* [H] by sling
    length* [L].

b. Divide sling height* [H] by sling

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

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
Reduced sling rating in this configuration = .667
(RF) x 6,000 lbs. = 4,000 lbs. of lifting capacity
per sling

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) = 1,000
lbs. per sling

Sling capacity decreases as the angle
from horizontal decrease. Sling angles
of less than 30° are not recommended.
