Pulleys are used for raising equipment and for making haul systems in a rescue situation. Some of them can be combined with a rope clamp to facilitate maneuvers; others allow movement along rope or cable.
PULLEYS
Haul System Ready-to-use kit, designed to easily pick off and lower (or simply pick off) a victim.
Transport Pulleys Pulleys designed for movement along a rope or cable.
Single Pulleys Lightweight, versatile pulleys designed for situations that do not require a high level of efficiency (such as redirecting the rope).
Prusik Pulleys High-performance pulleys designed for use with a Prusik friction hitch to build a lightweight progress- capture system. The shape of the side plates allows the knot to be released when it stops against the pulley.
Pulley-Carabiners Pulley-carabiners with excellent efficiency.
High-Efficiency Pulleys With Swivel High-performance pulleys equipped with a swivel, making them drop-resistant while installing the rope.
High-Efficiency Pulleys Versatile, high-performance pulleys adapted for intensive use.
Progress-Capture Pulleys Pulleys with an integrated progress-capture system may be used to replace a traditional pulley/rope clamp setup in haul systems.
Two factors determine a pulley s efficiency: Sheave size: the larger the sheave diameter, the higher the efficiency Bushings and bearings: - Self-lubricating bushings are efficient, but they must be regularly maintained - Sealed ball bearings are very efficient, and they do not require any maintenance
