Ratchet Tie-Down Strap Load Limits

Based on the provided sources, examples of working load limits and breaking strengths for various ratchet tie-down straps include:

The working load limit (WLL) and breaking strength of ratchet tie-down straps vary depending on factors such as the strap's width, length, material, construction, and end fittings. The working load limit is the maximum weight or force that should be applied to a strap in a normal, everyday application, while the breaking strength is the minimum force that will cause the strap to fail. Industry standards, such as those from the Web Sling & Tie Down Association (WSTDA) and the Department of Transportation (DOT), require the working load limit to not exceed 1/3 of the rated capacity or breaking strength [5].

  • Some ratchet straps have a Working Load Limit ranging from 1000 to 1499 lbs [1].
  • A 4-piece set of 16 feet long x 1-1/2 inches wide straps has a 1,000 pound working strength and a 3,000 pound breaking strength [2].
