Singing Rock PULLEY EXTRA HD – High-Strength Professional Pulley

Singing Rock PULLEY EXTRA HD is a robust high-strength single pulley developed for the most demanding industrial applications, hauling systems and professional work at height.

It is particularly suitable for use in the energy sector, including installation of electrical power lines. The pulley can be used with static and dynamic textile ropes up to 16 mm in diameter and is also suitable for high-strength textile ropes capable of replacing steel wire ropes in appropriate systems.

The high-quality self-lubricating sintered bronze friction bearing provides excellent durability at low speeds and efficiency of up to 86%.

The pulley is designed and optimised for use with a Prusik friction knot or mechanical rope clamp. Its large attachment point can accommodate up to three carabiners.

The side plates protect the rope from contact with surrounding objects and help prevent damage to the sheave. Openings in the side plates allow easy cleaning of the area around the bearing.
