WEBMASTER 1600 SLINGS

Type U Unilink Hardware Slings

type u unilink 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 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
points.
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

  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.

Note: 2", 3" and 4" Hardware slings feature Unilink fittings. Cells with red prices indicate shorter than recommended
lengths and may require reduced capacity ratings and/or
body lenghts.
Web-Trap Triangles and Chokers are also available.
Three and four ply hardware slings and wider width hardware
slings are available upon request.
*
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°.

WEB SLING HARDWARE
Steel Unilink Web Sling Hardware
Combination Triangle and Choker Fitting

U. S. Patent No. 4789193
web sling
This forged, high carbon steel fitting, functions as both
a triangle and choker.
Features, Advantages and Benefits
Promotes Safety
Forged steel for strength and reliability
Smooth rounded profile helps protect sling,
   worker and load
Saves Money
May be rewebbed to reduce cost
Zinc dichromate plated for longer life
Unilinks cost less than triangle/choker combinations
Saves Time
Large Crane hook opening - speeds rigging
Positive Web-Trap capture - no need to stop and
   reposition web
Functions both as a triangle and a choker
  - choke with either end
Forged Aluminum Triangles and Chokers
Aluminum is severely degraded by alkali, caustic
environments, acids and salt water.
chocker sling
Aluminum Triangles and Chokers are available
but may only be used with single ply web slings
within the rated capacities shown in the table.
They should not be used with Dura-Web 2000
webbing.
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.

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.
Avoid contact of hardware with load edges.
Unilink has the same rated capacities as TT or TC slings.

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:
Tuff-Tag and Warning Sheet
NYLON POLYESTER
Treated 10% Treated 7%
Untreated 6% Untreated 3%
A Warning Sheet is
included with every web
sling order. The sheet lists
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.
Effect of Angle of Lift on a Sling's Rated Capacity
DEFINITION
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?
choker hitch vertical hitch What capacity sling do I need?
1. Determine the weight that the sling
    will be lifting [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. Using the angle from horizontal,
    read across the angle chart to the
    corresponding number of Tension
    Factor column.

b. Divide sling height* [H] by sling

b. Divide sling height* [H] by sling

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

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
Reduced sling rating in this configuration = .667
(RF) x 6,000 lbs. = 4,000 lbs. of lifting capacity
per sling

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) = 1,000
lbs. per sling

Sling capacity decreases as the angle
from hjorizontal decrease. Sling angles
of less than 30° are not recommended.
