  • Synthetic SlingsSynthetic Slings Sling capacity varies from manufacturer to manufacturer, it has no set standard like wire rope does. User must look at the Individual Sling Capacity Tag to determine Safe Lifting Capacity of that sling. If the Tag is not readable or is missing, Do not use it! Inspect sling before each days use, and as often as necessary during the day to assure safety of sling! Sharp edges can slice a sling in two without warning as the load is tensioned. Use softeners or padding on corners.

  • Protecting Rigging FromProtecting Rigging From Damage or EnvironmentDamage or Environment Rigging components are expensive to buy and to replace! Use them properly and store them properly! Keep wire rope slings lubricated and all rigging stored out of the weather. Treat the rigging as though your life depended on it! Because it does if it fails! Dont use makeshift rigging or attempt to repair any rigging components. Knots tied in rigging reduces the strength by 50% or more!
