|
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. |

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. |

|
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? |

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. |
