What is a Working Load Limit?Date: August 22, 2023
The determination of Working Load Limits is based on the ultimate amount of breaking strength to failure, which is divided by three. For instance, a strap with a breaking strength of 10,000 lbs. would have a Working Load Limit of 3,333 lbs. It is important to note that, even though the strap may not fail until a force of 10,000 lbs. is applied, it is advisable to adhere to the 3,333 lbs. Working Load Limit in such circumstances. It is crucial to bear in mind that Working Load Limits were established to ensure safety during the transportation of cargo. If there is any doubt about the safety of transporting a load with the number or strength of straps, it is recommended to add more straps or switch to a heavier duty working load limit strap to maintain safety. It is worth noting that there is no harm in adding too many straps, but there is a significant risk in not using enough straps to secure loads. Additionally, it is advisable to ensure that the straps used to secure the load are in different areas of the cargo to prevent sudden braking, sudden lane changes, or debris on the road causing a swift motion to avoid. In the United States, there are severe penalties, fines, and potential imprisonment for non-compliance with the Department of Transportation's general guidelines for transporting cargo on roadways. It is essential to familiarize oneself with these regulations by reviewing the cargo securement general guidelines in your state.
