Choosing the right sling for lighting can be confusing, but it’s important to take the environment and conditions where the lifting sling will be used into consideration.

Nylon lifting sling

Nylon lifting slings are a popular choice because of their multi-purpose uses. A nylon web sling is unaffected by petroleum products like grease and oil. Nylon slings are also resilient to specific chemicals including ethers, strong alkalies and aldehydes.

Nylon webbing is not a good choice for uses involving bleaching agents or acids, or for use in temperatures over 194 degrees Fahrenheit (90 degrees Celsius). Nylon also stretches at approximately 8-10%, so it should not be used when elongation is not intended.

Polyester lifting sling

Like a nylon lifting straps, polyester round slings also have temperature guidelines, and are not advised for use in temperatures over 194 degrees Fahrenheit (90 degrees Celsius).

Unlike nylon, they will stretch only approximately 3% of its rated capacity. A polyester round sling can handle acidic environments because the fabric is not affected by bleaching agents or common acids. Polyester webbing, however, should not be used if it will come in contact with sulfuric acids or alkaline.

Chain lifting sling

Chain lifting slings are ideal for rugged environments and jobs. They resist abrasions, cutting and can maintain their strength and integrity even in extremely high temperatures up to 400 degrees Fahrenheit (204 degree Celsius).

Chain slings are generally constructed in Grade 80 steel, but a Grade 100 chain is usually available on request. Grade 100 chain offers more strength (about 25% more) for lifting chains, yet weighs less than traditional Grade 80 lift chains. Another benefit of a chain sling is its ability to be customized for almost any type of lift.

However, a chain hoist can be expensive and the prices can vary due to the market fluctuations.

Wire rope lifting sling

Wire rope slings are similar to a chain sling in that it offers excellent durability, strength and resistance to high temperatures. Wire rope, however, is more cost-efficient than chain so it’s a great choice is price is a concern. Because abrasion-resistance and flexibility of the wire rope can change depending on its configuration, a chain sling can be manufactured using a specific type of wire rope.

Typically, wire rope is made from either 6x19 or 6x37 classes of rope. A 6x19 is the most widely used because of its ideal combination of flexibility and abrasion resistance. A 6x37 class rope is more flexible, but offers less resistance to abrasion.

Other factors will go into determining which lifting sling type is best for your specific job, such as the item(s) being lifted, capacities needed, etc. For help choosing a lift sling, call our product specialists at 800-660-3585. They’ll be happy to any answer questions you may have.
