Hoists are often used when materials are too heavy or bulky to be safely moved manually. Because hoists rely upon slings to hold their suspended loads, slings are the most commonly used materials-handling apparatus. Slings, chokers, shackles and hoists are are available in many different materials and styles. Slings are commonly used in combination with a lifting device, such as an overhead crane, hoist, or forklift. The four main types of slings are: Wire Rope: The most commonly used sling. Used in the construction and other applications where heavy loads and rugged conditions exist. Chain: Combines superior strength, ease of handling and durability. The combination of heavy loads, elevated working temperatures and severe lift conditions usually dictate that an alloy chain sling be used. Mesh: Wire and Chain. Excellent in lifting objects that are hot or have sharp edges, such as bar stock or plate steel. Mesh slings usually have wide load bearing surfaces that greatly enhance load balancing. Machine shops and steel warehouses typically have applications requiring mesh slings. Synthetic: Both web and round-slings are used where loads must be protected from damage. Their light weight and flexibility reduce fatigue and strain on the rigger. The sections below serve as a guideline when hoisting or rigging at Princeton University.
