About Mazzella QOL Welded Alloy Chain
The Mazzella QOL grade 100 alloy steel quadruple, fixed-leg welded chain sling has an oblong master link and a latch lock hook on each of the four legs for lifting loads with a four-point bridle 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 an oblong master link at the top of the sling and a latch lock hook, also called a Latchlok hook, on each of the four chain legs for four-point bridle lifting configurations. The length of the four legs extending from the master link cannot be adjusted. A latch lock hook has a large eye that can connect to wire rope thimbles; the latch that closes over the eye prevents the hook from snagging and allows for more secure rigging than a foundry, grab, or sling hook. A recessed push button prevents accidental opening of the latch. The welded construction of this chain sling is more durable than mechanical construction. 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
