About: ISC - ALF Climb Assist Pulley
The ALF is a two-way locking pulley, designed to be used as part of a continuous loop system, in order to protect climbers as they climb vertical structures. The ALF is ideal for use on ladder climbs and in Ropes Course applications. Fall distance is limited to a few centimeters, so following a fall, most climbers are able to regain their grip on the structure, to resume their climb, unaided by staff. When a rescue is required, this can often be carried out from the safety of the ground.
The ALF is also a protection solution for workers on towers, masts, Wind Turbines and even in construction applications where a cost-effective, temporary climb assist solution is required for short duration working.
The ALF has been field trialed and cycle tested by over 4000 users with no detriment to performance and with little or no wear. The Alf has been extensively drop tested, in line with both CE EN360 and ANSI Z359. The unit has also been tested with weights other than those required for CE and ANSI Standards and has been statically pulled to destruction- making it probably the safest Climb Assist product in the world!
- The ALF Climb Assist Pulley uses a uniquely designed locking system, which combines a speed sensitive inertia locking brake system, with a grooved pulley wheel. At low speed (during normal use), the rope runs freely through the pulley. In the event of a fall, the rope speed increases causing the brake to lock to promptly arrest the fall. Fall distances are extremely short, so in most cases, the fallen user can regain their grip on the structure and resume the climb, without the need for assistance/instruction.
- The ALF Pulley is a two-way locking device which can be rigged in a continuous loop system with Alpine Butterfly attachment loops at opposing ends of the system. This means that at the end of each climb/descent, there is always an attachment loop present, allowing the next user to immediately commence their climb/descent.
