Polyester Round Sling Endless Loop - Vertical Hitch Cap: 6,000 lbs - Length: 12 ft
Item: Polyester Round Sling. Endless Loop. Vertical Hitch Capacity: 6,000 lbs - Length: 12 feet. Color: Green
Application: Used for general purpose material handling, rigging, overhead hoisting, and crane lifting. Used in vertical, choker, and basket hitches. Superior in its ability to conform to the shape of the load
Description: The Endless Polyester Round Sling, formed by endless yarns of 100% synthetic fiber, is encased in a tough polyester woven sleeve. This construction forms a round cross-section. A double jacket construction offers protection to the polyester load-bearing fibers. The polyester sling is color coded and tagged for easy identification. The endless sling forms a loop and the normal rotation from one lifting application to the next constantly changes the bearing point. This results in extended life. Flexible and lightweight, it is very economical and is the most versatile polyester sling, as it can be used in all three types of hitch arrangements. The polyester sling provides easier release from a choker hitch compared to other lifting slings and has a low 3% elongation at the rated capacity. Very flexible, this polyester sling conforms easily to the shape of the load without scratching and scraping. A polyester sling can be seriously degraded at temperatures exceeding of 194° (degrees) Fahrenheit. This type of round sling is resistant against a range of chemicals but not resistant against Acids and strong Alkalis.
Quality: Manufactured in the USA from synthetic fiber rope and a sleeve. Each round sling bears a tag displaying the rated capacity. Meets or exceeds overhead lifting safety standards under ASME B30.9
The Difference: Low quality lifting products can cause injury and damage. A look-a-like polyester slings, often found at lower prices, are also often advertised to conform to the same safety standards, if at all. Be aware that it may refer to safety ratings in effect decades ago. So for example, under the same safety standard a decade ago, a polyester sling may be rated to 100% without proof load testing, while today it may be 300% with proof load testing. Be assured that we only sell the highest quality polyester slings and our advertised safety standards conform to the current ASME standards.
Industry Designation: A polyester sling is also called a 'round sling' or 'lifting sling' in the rigging industry.

Learn: Construction of a Polyester Sling
A polyester round sling is made up of polyester fiber strands,
protected inside a polyester sleeve. The rope strands are the load-bearing
components while the sleeve simply shields the strands from cuts and abrasion.
Learn: The Quality Difference
A low quality polyester sling can cause injury
and damage. Look-alike polyester slings often found at lower prices are also
often advertised to conform to the same safety standards (if at all). Be aware
that it may refer to safety ratings in effect decades ago. So for example under
the same safety standard a decade ago, a round sling may be rated to 100% without proof
load testing while today it may be 300% with proof load
testing. Be assured that we only sell the highest quality polyester slings and
our advertised safety standards conform to the current ASME standards.
Learn: Different uses of polyester round slings:
To accommodate various applications, polyester slings can be
utilized using a vertical hitch, choker hitch, basket hitch or bridle hitch.
See diagram below. It is important to know, however, that the load capacities
change with the type of hitch and angle of use.
Learn: How capacities change with varying angle of use:
Working load limits (capacity) of a polyester sling vary depending
on the angle of use. The capacity is reduced as the angle of use declines. See
drawing below how a 1,000 lbs capacity is reduced as the angle of use declines.
The capacity of the round sling is always highest at a 90 degree angle of use
and smallest at an angle of 30 degrees (or less).
Learn: When and how to choose a fabric sling:
In the field, textile fiber slings such as nylon or polyester
slings are often commonly referred to as “chokers”. The polyester sling has the
advantage of being lightweight. It is very flexible and relatively soft;
therefore, it is suitable in applications were minimal damage to the load’s
surface finish is important.
Without adequate protection, synthetic fiber polyester slings are
susceptible to abrasion or being severed when impinged on even a moderately
sharp edge. Wear pads and sleeves (added thickness material) are available to
provide abrasion protection at vulnerable points along the polyester sling.
Some styles of polyester slings are encased in a nylon jacket for extra
Textile synthetic fiber slings can be fabricated to be endless
(also known as a grommet sling) or with an eye at each end. Eyes on the polyester
sling can be plain or fitted with various metal end fittings to allow
vertical, choker, or basket hitch lift arrangements.
Learn: The difference between Nylon versus Polyester slings:
Both materials - nylon and polyester slings - are strong,
lightweight, and very flexible; they can be used safely at temperatures up to
200� degreeF. The difference between the two
materials falls into the categories of elongation under load and chemical
Even when treated for abrasion, nylon can stretch up to 10% of its
initial length under rated load. This is contrasted to only 3% elongation for
Nylon is resistant to most regularly encountered chemicals with
the exception of concentrated acids and bleaches. While not as much of a
problem, prolonged exposure to sunlight results in UV degradation of nylon. A
polyester sling, while disintegrated by concentrated sulfuric acid, is
resistant to most other acids and most other chemicals. Polyester slings should
be avoided where aldehydes or ethers are present and where strong alkalis at
elevated temperatures are encountered.
Learn: Industry designation:
A polyester sling is also called a round sling. The
name "round sling" does not come from the endless loop construction
but rather from the round cross-section of the sling.
