Reckless and Ridiculous For years we have taken the high road and not responded in kind to ridiculous Working Load Limit (WLL) claims made in our industry. For years, we have assumed you would see through these silly claims; silly claims meant to lead safety and fleet professionals to choose light duty, consumer quality, imported […]
Assessing the WLL of a Cargo Restraint Device
The 2-Minute Test If you have any questions on the legitimacy of a working load limit (WLL) rating on your restraint net or traditional tie-down, put it to this simple test. Take the advertised WLL and multiply by a safety factor of 3 to get the weakest link tensile (Product WLL) X (Safety Factor of […]
The Purpose of Working Load Limits (WLL)
Safety Matters In my previous blog post we discussed the mathematics of how the Working Load Limits (WLL) is a relatively small percentage of the actual strength of the components. Now let’s discuss the rationale of making it so small. Simply put: SAFETY. The device must not fail. Life, limb and property depend upon proper […]
Working Load Limits – Why So Low?
We have had many questions over the years on properly determining the working load limit for cargo control devices like the Original BEDNET® Cargo Restraint. The Federal Motor Vehicle Safety Administration defines WLL this way: “The working load limit (WLL) of a tie-down, associated connector or attachment mechanism is the lowest working load limit of […]
