nylon endless web sling has heavy-duty one-ply webbing for lifting fragile or
irregularly shaped loads with vertical, choker, or basket configurations in
construction, general industry, and other low-heat applications. The nylon
webbing is soft to avoid scratching fragile or delicate loads. This web sling
is flexible and conforms to irregularly shaped loads, and has a better
strength-to-weight ratio than a wire rope or chain sling. This nylon web sling
resists several chemicals, including alcohols, aldehydes, strong alkalis,
ethers, hydrocarbons, ketones, oils, detergents, and sea water. However, it
does not resist acids or bleach agents. The stretch of a nylon sling at its
maximum load capacity is approximately 8-10%. This endless (also called type 5
or grommet) sling is made of a continuous loop of webbing formed by joining
the ends of the webbing with a load-bearing splice, and can be used in
vertical, choker, and basket lifting configurations. The load-bearing or wear
points of an endless sling can be rotated each time it is used, which can help
increase its life when compared to an eye-and-eye web sling. The sling's
heavy-duty webbing is denser and has a higher capacity than light-duty one-ply
webbing, but it has a lower capacity than a two- or four-ply web sling. When
the sling's red warning yarn becomes visible, this indicates the sling is no
longer fit for use. This sling meets American Society of Mechanical Engineers
(ASME) specification B30.9 and Occupational Safety and Health Administration
(OSHA) specification 1910.184. Slings are used to lift heavy objects for
industrial applications. Types of slings include web slings, wire rope slings,
chain slings, and mesh slings. The appropriate type of sling for an
application depends on the strength-to-weight ratio, flexibility and
resistance to bending, resistance to abrasion and cutting, resistance to
crushing, resistance to stretching, and resistance to high temperatures and
other environmental stressors. Slings have one, two, three, or four legs; or a
continuous loop of webbing. Legs are support branches that extend from a
single point at the top of the sling to the item being lifted so the weight of
the load is distributed evenly among the branches. Slings have eyes (loops) or
alloy steel fittings on the ends. A vertical lifting configuration connects a
crane hook directly to a load with a single, vertical sling, usually by means
of a hook. In a choker configuration, the sling wraps entirely around the
load, and one loop passes through the other to form a slip noose, or choker.
In a basket configuration, the sling passes under the load and both ends of
the sling connect to the crane hook. Load capacity is the maximum weight to be
lifted in a vertical configuration. The capacity in a choker configuration is
approximately equal to the vertical capacity times 0.8. The capacity in a
basket configuration, with sling ends at a 90-degree angle, is approximately
equal to twice the vertical capacity. Load capacity in a basket configuration
decreases if the angle of the sling is less than 90 degrees. For example, a
sling with a capacity of 2,000 lb. in a vertical configuration will have an
approximate capacity of (2,000)(0.8)=1,600 lb. in a choker configuration and
an approximate capacity of (2,000)(2)=4,000 lb. in a basket configuration, if
the sling ends are at a 90-degree angle to the load. Mazzella Lifting
