Top Lifting

If you are involved in sourcing, inspecting, or testing synthetic lifting equipment, you may have encountered a puzzling detail: upon inspecting the internal structure of a continuous endless Round Sling (EN 1492-2 / ASME B30.9) , the inner load-bearing core yarns are neatly bundled together using plastic adhesive tape. At first glance, buyers or field inspectors often ask: “Is adhesive tape strong enough for heavy lifting?” “Will the tape peel off or slip under tension?” “Is this a standard manufacturing practice in the USA and Europe, or a quality shortcut?” In this article, we will break down the engineering principles, standard international manufacturing procedures, and force-physics behind Core Yarn Bundling Tape —explaining why this method is universally trusted across global rigging production lines. Why Tape Will Never Slip or Impact Lifting Capacity？ To address safety concerns directly: the tape inside a round sling bears zero lifting load and cannot slip or fall out during ...
