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.
The JR and JRB pulleys are double pulleys with a max rope diameter for of 9 mm.
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.
The unique shape of SMC's aluminum side plates allows the efficient use of prusik hitches as a belay or progress capture device. Constructed with a 3-inch diameter sheave running on a high-efficiency ball bearing. Low profile fasteners help eliminate the possibility of the pulley snagging. Pulley will accommodate up to 13 mm rope.
