  • Good abrasion resistance
  • Resistance to metal loss and deformation
  • 8-strand construction
  • PFV-coated core distributes radial stresses when bending over sheaves and protects the rope from internal nicking



An 8-strand wire rope created to provide operating characteristics essential to drag ropes, and only available from Union. Our proprietary metallurgy was utilized in developing special rod chemistry requirements to provide optimum wire characteristics for mining ropes. The technology combines all aspects of rope manufacturing in one cohesive process that assures a product that’s second to none.

With eight outer strands, PowerMax® is more fatigue resistant than 6-strand ropes of the same diameter, plus, its greater surface area puts more steel in touch with contact surfaces, reducing wear and abrasion.

Just as importantly, no other mining rope is subjected to more rigorous standards of manufacturing than PowerMax. The industry’s highest manufacturing standards, continuous tracking and testing, and the use of enhanced plastics in core impregnation give PowerMax a clear-cut edge in hoist rope performance.
