Synthetic Hoist Rope the New Wire Rope

Synthetic Hoist Rope on Manitowoc Grove CraneAt CONEXPO 2014, earlier this month, Samson announced that the Manitowoc Grove RT 770E will be equipped with the first synthetic hoist rope for mobile cranes. Samson’s partnership with Manitowoc has allowed them to enter the crane industry to provide a product with numerous benefits.

  • 80% lighter than wire rope
  • Same load pull and chart with 5:1 safety factor
  • No rusting
  • No lubricating
  • No kinking, birdcaging, or damage from winch drum
  • Eliminates load spin and cabling

To prove the viability of synthetic hoist rope, Manitowoc and Samson conducted lab testing and field trials to find tensile strength and fatigue, bend fatigue, and effects from temperature. Tests were conducted at two Samson labs and two third-party labs where more than 4.6 miles of rope was manufactured and tested.
