Product Description

The Mazzella WLA1 nylon single-leg web sling has flat attached eye-and-eye endings, heavy-duty one-ply webbing, and an extra-wide sling body for lifting bulky loads with basket configurations in construction, industrial, 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%.

The extra-wide sling body of this web sling is suitable for lifting bulky loads that require wider load-bearing areas than standard-width web slings. This flat eye-and-eye (also called type 3) sling has an eye, or loop, sewn onto both ends, and can be used with basket lifting configurations. The attached eyes are suitable for lifting loads that require less strength than a continuous eye wide-lift 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. 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 or wire rope. 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. The load capacity of a web sling 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 of a web sling in a basket configuration, with sling ends at a 90-degree angle, is approximately equal to twice the vertical capacity. Load capacity of a web sling in a basket configuration decreases if the angle of the sling is less than 90 degrees. For example, a web 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 Technologies manufactures lifting solutions including slings, cranes, and hoists. Founded in 1954, the company is headquartered in Cleveland, OH.
