CMC Rescue

HD Pulleys

No detail has been overlooked in our redesign of the ProSeries® Pulleys. Built workhorse tough to deliver years of dependable service, these HD (Heavy Duty) Pulleys are loaded with enhanced features including:

  • Large high-efficiency anodized aluminum sheave;
  • High-strength sealed bearings that minimize loss of mechanical advantage and will deliver optimum performance haul after haul;
  • Side plates constructed of machined aircraft-grade aluminum, with smooth rounded edges to minimize rope fraying;
  • Wide attachment point that supports multiple rescue-size carabiners;
  • PMP (Prusik-Minding Pulley) bottom shaped for maximum efficiency with Prusik hitches and also works well with mechanical rope-grabs.

Do not load a single side only of a double sheave pulley.
Working-At-Height / Industrial Rope Access / Technical Rope Rescue
Working at height requires reliable, quality equipment. The HD Pulleys can be used with confidence in work-at-height maneuvers for industrial rope access or technical rope rescue when used in accordance with the regulatory safety standards they fall under. Always use life safety equipment and gear according to the regulatory safety standards for which it is classified and/or certified.
