WEBMASTER 1600 SLINGS

Type 2 (TT) Web-Trap Hardware Slings
web-trap hardware slings 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 2 (TT) - Has a Web-Trap triangle on
each end. Normally used in a basket hitch, but
can also be used in a vertical hitch. They cannot
be used as a choker.
Webmaster 1600 Nylon and Polyester* Slings
The Industrial Standard Heavy Duty Sling
This grade of synthetic web sling is popular because most users
consider it's strength and service life a good buy.
Webmaster Features, Advantages and Benefits
Promotes Safety Saves Money
• Red core yarn warning system aids in the inspection
  process. 		• Yellow treatment for abrasion resistance and extended
  sling life.
• Tuff-Tag provides serial numbered identification for
  traceability.		 • Tuff-Tag provides required OSHA information for
  the life of the sling, not just the life of the tag.
• Proven sling web construction. * Note: Polyester web is identified by single blue
surface stripe.

Note: 2", 3", and 4" Hardware
Slings feature Unilink fittings.

Three and four ply hardware
slings are available upon request.
Web-Trap Triangles and
Chokers are also available.
** Type 2 (TT) can not be used
in a choker hitch.
*** Replace the "D" with an "N"
to order nylon.
* 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 Angle chart at bottom of page.
Always protect synthetic slings from being cut by corners and edges. See the Sling Protection below.

Web-Trap Steel Sling Hardware - Triangles and Chokers
A significant improvement in triangle/choker design, Web-Trap fittings feature positive web capture to eliminate
web slippage. These fittings are manufactured from alloy steel for lighter sling weight and a powder-coated finish
to inhibit rust.

WEB SLING INFORMATION
Sling Length Tolerance for Web Slings Anti-Abrasion Treatment
Sling Type Tolerance *
1 Ply 1.5" + 1.5% of sling length
2 Ply 2.0" + 2% of sling length
3 & 4 Ply 3.0" + 3% of sling length
We recommend that web slings be manufactured from
abrasion resistant latex treated webbing. Treatment is
standard on both nylon and polyester web slings.
Natural, untreated webbing is available upon request.
Note: Heavy duty treatments are available as a
supplemental process for greater protection.
* For web sling widths wider than 6", add 1/2" to these values.
For tighter tolerance or matched set length requirements,
please consult with Customer Service.
Elasticity - The stretch characteristics of web slings
depends on the type of yarn and the web finish.
Approximate stretch at RATED SLING CAPACITY is:

A Warning Sheet is
included with every web
sling order. The sheet lists
inspection information
and operating practices
applying to synthetic web
slings.		 warning sheet for 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.
Sling Protection
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.
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
