Product Details

Product Description

The Mazzella SSS grade 100 alloy steel single, fixed-leg mechanical chain sling has a sling hook on each end for lifting loads with a single-point vertical configuration in abrasive and high-temperature environments such as foundries and steel mills. This chain sling is made of grade 100 alloy steel, which is stronger than grade 80 alloy steel. It has greater temperature and abrasion resistance than a web or wire rope sling. The sling has a sling hook on each end for single-point vertical lifting assemblies. This single, fixed-leg chain sling has one branch of chain whose length cannot be adjusted, and the sling hooks have a narrower opening than a foundry hook and a wider opening than a grab hook. The mechanical construction allows for repair of individual components of the sling without replacing the entire sling. A chain sling does not stretch at its maximum load capacity, but it can stretch up to 20% before its breaking point, to provide shock resistance. 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. 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 two-point, three-point, and four-point bridle configurations, the sling attaches to the load at two, three, and four locations, respectively, in such a way that each leg is at the same angle to the load. Load capacity is the maximum weight to be lifted in either a vertical configuration (single-leg slings) or at a 60-degree angle (two-, three-, and four-leg slings). A chain sling's capacity at a 45-degree angle is approximately equal to the 60-degree capacity times 0.8, and its capacity at a 30-degree angle is approximately equal to the 60-degree capacity times 0.57. For example, a chain sling with a capacity of 2,000 lb. at a 60-degree angle will have an approximate capacity of (2,000)(0.8)=1,600 lb. at a 45-degree angle and an approximate capacity of (2,000)(0.57)=1,140 lb. at a 30-degree angle.

Mazzella Lifting Technologies manufactures lifting solutions including slings, cranes, and hoists. Founded in 1954, the company is headquartered in Cleveland, OH.
