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. |

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. |

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 hjorizontal decrease. Sling angles
of less than 30° are not recommended. |
