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? 







What
capacity sling do I need? 















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. 











OR 



















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


















OR 



















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

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
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.
