This lightweight, full-strength, Prusik-minding pulley is ideal for mountain rescue, swiftwater, or other technical teams where equipment weight is a significant consideration.
By machining the side plates, the thickness of the metal can be varied to maximize the strength-to-weight ratio, a process that cannot be done with traditional bent metal side plates. Sealed ball bearings provide high efficiency and aluminum side plates protect the rope. An extremely low-profile stainless steel axle assembly reduces snagging on rocks, roots, and uneven surfaces.
Designed for lifelines up to 1/2 inch (13mm) in diameter.
The JR and JRB pulleys are double pulleys with a max rope diameter for of 9 mm.
The TR Pulley is strong, reliable compact, and lightweight. It is reasonably priced but doesn't sacrifice efficiency. Great performance for its size and cost. The TR Pulley has a true Oilite Bearing on a zinc coated axle for reliable performance.
Noting the unique requirements found in Swift Water Rescue, we created an entirely new pulley to address those needs. The Swiftwater Rescue Pulley represents a reasonably priced, non-NFPA alternative to other midsized pulleys.
Made using high quality aluminum, this lightweight pulley weighs 6 oz. and features a 2‰۪‰۪ sheave. Anodized side plates feature a series of holes that help to minimize the hydroplaning effect that might occur with a typical pulley. These side plates are also configured to work as a Prusik Minding Pulley and are precisely tensioned for easy one-handed operation and secure placement at any point along the rope.
High quality sealed ball bearings help to provide the optimal efficiency that is so crucial in rope rescue systems. They help to reduce the performance-robbing resistance that is inherent in most multiple component systems and are not prone to failure under misaligned loads or with twisted gear that may occur with needle bearings.
The wide and flat base maximizes the effectiveness of a Prusik hitch while a unique side plate formation allows the use of larger ropes in a compact pulley. The top hole accepts 2 large rescue carabiners or multiple small carabiners and allows the carabiners to be rotated freely and completely even while closed.
