When manufacturing lifting slings or lashing straps, tensile testing is one of the most important quality control procedures. However, a common question is: Can the same testing machine be used for both lifting slings and lashing straps? The short answer is: sometimes, but the testing setup is not the same. A hydraulic tensile testing machine may look similar when testing different textile products, but the fixture, sample arrangement, loading speed, test method, capacity and applicable standard can be completely different. For manufacturers and buyers of lifting and cargo securing products, understanding these differences is important when selecting a testing machine and interpreting test results. The Main Difference Between the Two Testing Machines. The biggest difference is not necessarily the hydraulic frame itself. The more important difference is: How the product is mounted and how the load is applied. Item Lashing Strap Lifting Sling Main application Cargo securing Lifting Typic...

  How Fast Should You Test Lifting Slings? When testing lifting slings, most people focus on  test load  and  safety factor . But there is another critical parameter that is often overlooked:   Testing speed (loading rate). The speed at which the load is applied can directly affect: Test accuracy Safety during testing Final test results Sling performance evaluation In this article, we explain  why testing speed matters , how it affects different sling types, and best practices for setting the correct speed during sling testing. Why Testing Speed Matters for Lifting Slings Testing speed refers to  how fast the load is applied  to the sling during proof or breaking tests. If the loading speed is: Too fast  → shock load, unstable readings, unsafe conditions Too slow  → inefficient testing, possible creep effects on synthetic slings Proper speed ensures: Stable load application Accurate test data Compliance with industry standards Protection...
