ALF™ Locking Pulley

The ALF^TM Locking Pulley is an advanced, high-performance locking pulley system designed for professional rope access, rescue, and industrial height safety applications.

Engineered by ISC, this innovative pulley integrates an inertia reel / speed-sensitive locking mechanism directly into a grooved pulley wheel. This unique design allows the pulley to automatically lock under sudden load or rapid movement, providing enhanced safety for workers operating at height.

Unlike traditional systems, the ALF^TM Locking Pulley eliminates the need for an internal brake, allowing it to handle multiple load cycles and repeated arrests with minimal maintenance. This makes it particularly suitable for demanding environments such as construction, tower work, wind energy maintenance, and confined space operations.

The system can also be combined with Prusik pulleys to create 3:1 or 5:1 mechanical advantage systems, offering flexibility for lifting, hauling, and rescue scenarios.

Designed for Australian conditions, the ALF system complies with relevant safety standards and is trusted across industries where reliability and worker protection are critical.
