Mechanical Advantage Systems

The Petzl Jag System is an enclosed 4:1 progress capture pulley system that can be used for hauling, tensioning a system, pickoffs, making a releasable anchor, or evacuating a victim when paired with an I'D Descender. The Jag and Jag Traxion that create the system utilise sealed ball bearings to increase efficiency up to 91%, which with the 4:1 mechanical advantage, enable easier work to be done by the user.

The ISC HaulerBiner Compact Rescue System is a lightweight, compact and simple to use/deploy device. The HaulerBiner is fully rated for lifting people. It has three pulley wheels incorporated into each Karabiner, creating a compact and lightweight 6:1 or 7:1 (theoretical) Mechanical Advantage system. The HaulerBiner also has a purpose-designed progress capture cam with, an ‘on/off’ position. The HaulerBiner utilises purpose-developed 6mm (1/4") rope, for strength and easy handling/best grip. The kit is supplied in a two-pouch bag, for easy deployment.

The Lyon Casualty Pick Off Hoist may be used by a rescuer to 'unweight' a casualty to facilitate transfer onto a rescue system. Small enough to be carried on a rescuers harness, the hoist can be deployed in seconds to make an awkward task easy. Pre-packed in a high visibility two piece pouch, this very compact unit with its high efficiency pulleys is configured to create a theoretical 6:1 mechanical advantage.
