"A pulley for every purpose, from simple single sheathe pulleys to knot passing monsters!"

Pulleys can be used to haul equipment, tools and of course people. Some of our pulleys feature an integrated rope clamp to create a progress capture system. Transport and specialized pulleys allow progression along angled or horizontal rope and cables.

Our pulleys are divided into six families

  • Compact pulleys have a multitude of applications, they are often carried on the harness.
  • High-efficiency pulleys offer a good compromise between overall size, weight and sheathe diameter. Efficiency is improved further using ball bearings to support the sheathe.
  • Prussic pulleys have a flat base allowing them to be used with a prussic hitch to create a 'progress and capture' system.
  • Progress and capture pulleys allow simple hauling systems to be implemented quickly and easily.
  • Transport pulleys have been designed for Tyrolean traverses, their double sheathe design also allows complex mechanical advantage hauling systems to be designed.
  • Specialized pulleys designed to overcome specific issues such as moving along mechanical lift cables or passing knots.

Pulley design effects selection of attaching elements

  • Fixed sided pulleys such as the Petzl Fixe must be used with symmetrically shaped connectors such as the Petzl OK Oval Fixed side plate pulleys are quick to install when compared with their swing cheek counterparts.
  • Swing cheek pulleys such as the Petzl Rescue must be opened to install the rope, however they work with most common connector types.

Two factors determine a pulley’s efficiency

they must be regularly maintained.
Sealed ball bearings are very efficient, and they do not require any
