Professional Questions

  • Q What does WLL mean on the rigging products?

    A WLL is the abbreviation for Working Load Limit. It means the maximum allowable load that a piece of rigging equipment can safely lift; it is also sometimes called “rated load” or “rated capacity”. 

    Rigging users must be aware that the WLL of a piece of rigging may be reduced by several factors such as temperature, environment, and angle of loading or type of hitch used.
  • Q Does dirt and grease affect the strength or shorten the life of synthetics slings?

    A Dirty in a web/round sling can promote internal abrasion that can reduce sling strength and possibly shorten sling life.
  • Q What is the difference between G80 and G100 Chain?

    A Grade 100 chain slings are approximately 25% stronger than grade 80 chain slings of the same diameter. The chain is harder, resulting in greater abrasion resistance and, therefore, longer life.
