Stone Slings
Quick Info: Polyester Web Slings - Flat Eye & Eye -
Length: 8 feet - Capacity: Up to 18800
Country of Origin: USA
Application: A versatile sling adaptable for use as a
vertical, choker, or basket hitch used for rigging, stone handling, headstones,
construction slabs, concrete, and material handling.
Description: The Flat Eye & Eye polyester sling is a heavy-duty web sling. Flat loop eyes are oriented in same plane as sling body. Extremely versatile for all types of hitches. Easily removed from below the load when placed. Polyester offers lower stretch, acid & bleach resistance, and retains less moisture than nylon webbing.Lightweight, flexible, and relatively soft it is suitable in applications where minimal damage to load’s surface is important. It is resistant to most regularly encountered chemicals with exception sulfuric acids, strong alkalis, and ethers. Elevated temperatures above 200 degrees F significantly reduce the rated load capacity. While not as much of a problem, prolonged exposure to sunlight results in UV degradation of the sling.
Quality Standard: Sewn in the USA with name of the
manufacturer sewn-in for traceability and quality assurance. Bears a tag
displaying the rated capacity. Meets or exceeds overhead lifting safety
standards under ASME B30.9.
The Difference: Low quality products can cause injury and
damage. 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 Names: Also known as a ‘polyester web sling’ or ‘webbing sling’.
Includes: (1) one stone sling

- Never exceed Working Load Limits
A low-quality web sling can cause injury and damage. A
look-alike polyester stone sling often found at lower prices is 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 poly stone web 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.

How webbing polyester stone sling capacities change with
varying angle of use:
Working load limits (capacity) of poly stone slings 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 polyester stone sling’s capacity is always highest at a
90 degree angle of use and smallest at an angle of 30 degrees (or less).

About polyester web slings, classes, uses and
limitations:
In the field, a polyester stone sling is often commonly referred to as a 'choker'. The sling has the advantage of being lightweight. It is flexible and relatively soft: therefore, it is suitable in applications where minimal damage to load’s surface finish is important. When the flat style webbing sling is employed it can be wrapped around a load, evenly distributing the lifting force over a relatively wide area, thereby reducing the contact pressure. Without adequate protection, polyester slings are susceptible to abrasion or being severed when impinged on even a moderately sharp edge. We pads and sleeves (added thickness material) are available to provide abrasion protection at vulnerable points along the stone sling.
