**
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. |

DEFINITION |
|
|
as
used throughout this page, 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? |

Determine the weight that the sling
will be lifting [LW]. |

2.
Calculate the Tension Factor [TF]. |

Using the angle from horizontal,
read across the Angle Chart to the
corresponding number of the
Reduction Factor column. |

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
