Petzl RESCUE Pulley

The Petzl RESCUE pulley is a high-strength, prusik-minding pulley with a ball bearing sheave, built for hauling and rescue systems. Arborists use it for mechanical advantage setups, loaded redirects and aerial rescue kits.

Why a prusik-minding pulley

A prusik-minding pulley has square-cut side plates that stop a hitch from being pulled into the sheave. In a haul system, the progress-capture hitch sits against the pulley and holds the load when you stop pulling, so you can reset without losing ground.

That makes the RESCUE a good choice for tensioning lines, lifting a stuck piece in a mechanical advantage setup or building a system to lift or lower an injured climber. The ball bearing sheave keeps friction low so more of your effort goes into the load.

It is bigger and heavier than a hitch-tending pulley, so most climbers keep it in the rescue bag or rigging kit rather than on the saddle every day. That way it is ready for a planned haul or an aerial rescue without adding weight to every climb.

Use and care

Match your rope diameter to Petzl's stated range and keep the pulley clean of sap and grit. Check that the side plates swing and close properly and that the sheave spins smoothly.

Rescue systems need practice. Train with your crew so you can build them quickly, and use the pulley within Petzl's ratings and ANSI Z133 practice. Inspect it before each use and retire it if it is cracked or deformed. See other pulleys in micro pulleys.
