Tie Down Strap Tag Information: Break Strength and Working Load Limit

tie down strap sewing tag from U.S. Cargo Control

Tie down straps are universally known to secure cargo and other items in place. Moreover, they ensure safe and easy transport thanks to the rigorous testing they undergo. Our straps meet the various safety requirements set by standard cargo safety organizations such as the Web Sling & Tie Down Association (WSTDA) and North American Cargo Securement. They also meet the requirements from the Department of Transportation (DOT) and Commercial Vehicle Safety Alliance (CVSA). 

After testing, each webbing tie down strap gets a tag indicating its break strength and working load limit. This information overall indicates how much cargo can be tied down with this strap. Different lengths, widths, and makes of these straps have different limits. Be sure you know these terms before attempting to use these straps in your tie down systems.

What Does "Break Strength" Mean?

According to the WSTDA, the breaking strength means the load in pounds or kilograms at which point any load bearing part of the synthetic web tie down fails. This figure is usually expressed in pounds or kilograms. 

The product's breaking strength includes the breaking strengths of all components that make up the product. For example, if your strap's breaking strength equals 10,000 lbs. but the ratchet component's equals 8,000 lbs., this reduces the total breaking strength of the product to 8,000 lbs.

Keep this in mind when you decide on choosing the right tie down strap for your needs. You'll also want to keep in mind what it's working load limit is.

What Does "Working Load Limit" Mean?

The working load limit, also marked at WLL, means the maximum allowable load assigned to each synthetic web tie down by the manufacturer which is not to exceed one-third of the complete assembly breaking strength. This means a strap with a break strength of 16,200 lbs. would have a WLL of 5,400 lbs.

Why Are These Terms Important?

If you transport heavy or fragile loads on a regular basis, then these figures mean a lot to you. Knowing how much freight you can carry at one time stipulates the type of tie down necessary for the job - in other words, do you need a strap with a higher WLL or breaking strength?
