Ideal for machine shop or maintenance departments varied requirements.
Features, Advantages and Benefits
adjust a link chain sling
Promotes Safety
Alloy steel master control link - for strength and
    reliability
Grade 80 alloy chain - recommended for
    lifting applications
Each assembly serialized for traceability
Complies with OSHA - proof tested and
    certified
Saves Money
Versatile - one sling does many jobs
Less expensive than traditional chain slings
Using two Adjust-A-Links on the same crane
    hook eliminates the need for expensive triples
    and quads
Heat treated alloy steel construction, provides
   long sling life
Orange powder coating on master plate helps
   prevent rust - extends sling life.
Never substitute another chain or exceed the rated
capacity*. The load bearing chain must be seated at the
base of adjusting slot of the Master Control Link. The
alloy chain and Master Control Link shall not be used
separately for general purpose lifting.
Saves Time
Easily adjustable to accommodate a wide
    range of applications
No time wasted searching for just the right sling
chain slings control link
We recommend that Adjust-A-Link
assemblies not be used at angles less
than 45° from horizontal.

** 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.

Effect of Angle of Lift on a Sling's Rated Capacity
DEFINITION
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?

1. Determine the weight that the sling
   will be lifting [LW].
1. Calculate the Reduction Factor [RF].
2. Calculate the Tension Factor [TF].
a. Using the angle from horizontal,
    read across the Angle Chart to the
   corresponding number of the
   Reduction Factor column.

b. Divide sling height* [H] by sling

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