If you’re a professional in the heavy lift industry, it’s likely that you’ve encountered a good number of different types of slings. However, it's unfortunately common that people never get an opportunity to learn more about the equipment they use outside of the knowledge necessary to rig them up.
This article is devoted to some fascinating facts we’ve learned about Polyester Web Slings, which are one of the most popular sling types on the market today. By the end of this article, you should have some newfound appreciation for your polyester web slings.
1. Fantastic in Marine Environments Polyester web slings, believe it or not, are one of the most popular slings to use in marine environments. The reasoning for this is that the synthetic polyester fiber used to create the sling is naturally resistant to water and salt. Additionally, because the fibers are woven tightly into strong but thin plies, they do not tend to accumulate moisture or salt and become waterlogged like non-synthetic fiber materials. Polyester, being a plastic, is not subject to rust or oxidation from water, making polyester slings superior to chains or wire rope for marine use.
2. Comparatively Soft Polyester slings are often used to lift materials that are delicate, polished, or vulnerable to abrasion. This means that materials like fiberglass, polished metal sheets, and softwood are frequently lifted with polyester slings whose soft surface will not deteriorate the sensitive materials. As an added bonus, this strong-but-soft nature means that polyester slings themselves are resistant to abrasion, being less likely to become damaged from standard wear than many other material types.
3. Long Lifespan One of the best benefits of polyester slings is the fact that they have very long lifespans. A long lifespan saves you money, time, and headaches without constantly making you worry about potential wear. Part of the reason why polyester slings have such long lifespan is that they are not susceptible to mold, mildew, or bacterial deterioration. Being a plastic, there is almost nothing in the natural world that can deteriorate it; though, of course, there are chemicals that should be avoided when using polyester slings.
4. Good in Many Temperatures Another reason for the popularity of polyester slings is their relative resistance to temperatures. Unlike metal slings, which can contract, expand, or even become brittle in extreme temperatures, polyester slings are resistant to heat up to 180 degrees Fahrenheit (according to OSHA.gov research.) They are also unaffected by cold temperatures, which can often lead to unsafe conditions when using metal slings.
Given their usability across many temperatures, polyester slings see use in extremely hot climates, in addition to extremely cold climates. While winter work was previously even more dangerous than it is today, polyester slings have removed one more safety hazard from the workplace.
5. Fantastically Priced Polyester slings are often among the lowest-priced slings you can buy. Because they are a mass-producible synthetic, many slings can be made with very inexpensive batches of plastic fibers. Combining all of the facts above with the low purchasing cost of such slings, polyester slings can be an incredible choice for staying on a budget without sacrificing performance.
While polyester slings are not a magic solution, their versatility, low-price, and low maintenance requirements mean that they are the ideal for many companies doing general lifting work.
