Unilink and Web-Trap
hardware can help to
extend sling life by protecting the webbing from
abrasion on rough crane hooks. Hardware
can often be reused, lowering sling replacement
costs. |
|

|
Type
U (UU) - Has the preferred and economical
Unilink fitting on each end for use in a vertical,
choker or basket hitch. Unilinks allow choking
from either end to save time and vary wear

Do
not exceed rated capacities. Sling tension increases as the angle from horizontal
decreases. Slings
should not be used at angles of less than 30°. Refer to the Effect of

Always protect synthetic slings from being cut by corners and edges. See

Forged
from aircraft aluminum, this tough alloy
is stronger than mild steel. Aluminum has the
advantages of being lightweight, non-sparking
and does not rust. |
|
|
|
| Avoid
contact of hardware with load edges. |

|
|
Note: Aluminum triangles and chokers DO NOT
offer the advantages of the Web-Trap feature.
Aluminum fittings are not as durable and cost
more than steel. |

inspection information
and operating practices
applying to synthetic web
slings. |
 |
|
OSHA
requires all web slings to show rated capacities
and type of material. The Lift-All Tuff-Tag is made from
an abrasion resistant polymer that will remain legible far
longer than any leather or vinyl tags. In fact, a Tuff-Tag
will consistently outlast the useful life of a sling. |
|
|
|
|
|
|
|
|
|
Tuflex is an Alternative...
For three and four ply slings wider then
6", Tuflex Rounslings should be seriously considered.
Tuflex offers increased flexibility, ease of use and lower
cost. |

CUT
AND WEAR PROTECTION |
|
|
|
|
|
| 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. |

6,000 lbs.
Measured Length (L) = 6 ft.

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.

|
Sling
capacity decreases as the angle

of less than 30° are not recommended. |
