Slings
shown here are the most popular
of the traditional adjustable type slings. |
|
|
|
|
|
However
, our engineering staff can
design whatever configuration is required
to fit individual needs. |
|
**
Style B, single and double adjustable
slings are furnished with approximately
one (1) foot of chain in short branches
unless otherwise specified in the order.
Style A, hook is attached to master link
with a coupling link. |

**
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. |
|
|
|
![](images/warning_logo.jpg) |
|
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 |
![](images/warning_logo.jpg) |
|
as
used throughout this catalog, 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? |

2.
Calculate the Tension Factor [TF]. |

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 per sling |
