CUT

|
|
| Selection
of Sling Protection Products |
|
 |
|
Sling
protection products need to be used in applications where sling
damage may occur. Cutting of synthetic slings during use is
the number
one cause of sling accidents. A variety of factors influence
sling
protection performance. Since no material is fully cut proof,
a qualified
person must select materials and methods that adequately protect
slings from edges or surfaces. We can assist customers with
their
product selections. |
|
|
|
|
|
|
|
| Cut
Protection versus Wear Protection |
|
|
Our
sling protection products are divided into two categories, Cut
Protection and Wear Protection. Cut Protection
Products are designed to improve workplace safety. When placed
between slings and edges, cut protection products
act as a buffer to prevent sling cutting and to reduce bearing
pressure levels at contact areas. Wear protection
products serve to extend sling life by reducing abrasive wear
and prevent marring of the load surfaces.
The following table provides comparative sling protection performance
for standard products. |
|
|
 |
Performance
Rating: The bar graphs shown above reflect the comparative
performance of Our Cut Protection
products against commonly used loose and sewn-on types of Wear
Protection products.
Test Lift Qualification: To validate the suitability
of sling protection products for each application, always
complete one or more test lifts in a non-consequence manner.
Technical Bulletin MS-10 available for additional information. |

| 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. |

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. |

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. |

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 |
