The Singing Rock Extra Plus Roll Pulley is a durable, lightweight large pulley designed for industrial rope access, hauling systems and rescue applications where high efficiency, reliability and long service life are required
The Singing Rock Extra Plus’s large sheave diameter and sealed ball bearing system provide smooth operation with an efficiency rating of 94%, reducing friction and improving hauling performance.
Designed for use with both static and dynamic textile ropes, the Extra Plus Roll Pulley is optimised for use with Prusik friction knots and rope clamps, making it a versatile component for mechanical advantage systems. The forged sheave provides exceptional durability, while the anti-dust cover protects the ball bearing to extend the working life of the pulley in demanding environments.
The formed side plates help protect the rope from contact with surrounding surfaces, while the side plate openings allow easy cleaning around the bearing area. The top attachment point accommodates up to three carabiners, and an additional bottom attachment point with a 32 kN strength rating allows the construction of more complex pulley systems.
Individually marked with a unique production number, the Singing Rock Extra Plus Roll Pulley provides dependable performance for professional rope access technicians, rescue teams and industrial users requiring an efficient and robust hauling solution.
