Mechanical-Spliced

Engineering wire rope slings for your application is a highly specialized field – with exacting standards – that we gladly live by. A Union sling can meet or exceed the most exacting specifications. We apply thorough design and production controls – including an extensive ISO-controlled process. And our traceability process tracks every component through completion of the assembly and into the field.

A mechanical-spliced wire rope sling is constructed when eyes are formed using the Flemish eye splice. Ends are then secured by pressing a metal sleeve over the ends of the strands of the splice. Pull is directly along the centerline of rope and eye. This splicing method gives the most efficient use of rope capacity and proves to be economical.

  • Higher rated capacity than hand-spliced sling
  • Produced to ISO 9001:2008 certification practices
  • Customized to your specifications
