LiftAlloy BASKET TYPE CHAIN SLINGS
liftalloy chain slings

LiftAlloy chain slings, available in grade 100 for 7/32"
through 3/4", and grade 80 for 7/8" up to 1-1/4" 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.
Use of Chain Under Heat Conditions
When the chain itself is heated to temperatures shown
below, the Working Load Limit (Rated Capacity) should
be reduced as indicated.

¹Rated Capacity also referred to as Working Load Limit.
*
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.

CHAIN SLING BASICS
LiftAlloy Grade 100 Chain Wear Allowance
Determine wear by measuring cross section at link
ends. If worn to less than the minimum thickness
allowable, chain should be removed from service.
Available in sizes 7/32" through 3/4".
Higher capacity per chain size can be used as an
   increased safety factor.
Higher capacity may allow use of smaller diameter
    chain for your lifts, reducing sling weight and cost.
Extreme abrasion resistance - more durable.
Powder-coated attachments for corrosion resistance.
Minimum thickness
based on OSHA
recommendations.
LiftAlloy Grade 80
Available in sizes 7/8" through 1-1/4".
Greater temperature tolerance.

¹ Rated Capacity also referred to as Working Load Limit.
When using chain slings in a choke hitch, reduce the sling’s rated capacity by 20%
** 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 SLING ANGLE
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. The Increased Tension method provides the increased tension as a
function of the sling angle. Alternatively, the sling Reduced Capacity method may be used to determine reduced lift
capacity for any angle.
INCREASED TENSION
Determine capacity
of sling needed
 choker hitch
REDUCED CAPACITY
Calculate rating of each sling
rigged at this angle
1. Determine the load weight (LW). 1. Calculate the reduction factor (RF).
a. Using the angle from horizontal,
    read across the Angle Chart to
    the corresponding number of the
   Reduction Factor column.
2. Calculate the Tension Factor [TF].
a. Determine the sling angle as mea-
    sured from the horizontal, and the
    corresponding tension factor (TF)
    from the effect of angle chart.
-OR-
b. Divide sling height* (H) by sling
    length* (L).
-OR-
b. Length* (L) divided by height*
    (H)
2. Reduction factor (RF) x the sling’s
    rated capacity for the type hitch that
    will be used = sling’s reduced rating.
3. Determine the share of the load
    applied to each sling leg (LW).
4. Multiply (LW) by (TF) to determine
    the sling leg tension. The capacity of
    the selected sling or sling leg must
    meet the calculated tension value.		 *Measured from a common horizontal
plane to the hoisting hook.

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:
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
Sling capacity decreases as the angle
from horizontal decreases. Sling angles
of less than 30° are not recommended.
Reduced sling rating in this configuration
= .667
(RF) x 6,000 lbs. = 4,000 lbs. of lifting
capacity per sling
