Wire Rope 19 X 7 Rotation Resistant
Wire Rope 19 X 7 Rotation Resistant
Wire rope designed specifically to prevent spin, or rotation, when transporting a load. Designed for both single-part and multi-part applications that require no rotation, the 19 x 7 involves 6 strands of wire that lay in one direction around an inner core strand and an outer layer of 12 strands that lay in the opposite direction. This construction minimizes torque and the accompanying spin in any one direction. Used for hoisting single- or multi-part loads that require minimal rotation (elevator assemblies, crane assemblies, oil field and fracing applications, and excavation). Available through Trinity Sling from domestic and imported rope suppliers and customizable in different lengths and diameters.
