ISC - ALF Climb Assist Pulley - 2 Way Auto Locking

Brand: Ferno

Product Code: VISC RP430 ALF

Availability:In stock

The ALF Climb Assist Pulley from ISC is a protection solution for workers on towers, masts, Wind Turbines and even in various construction applications where a cost-effective, temporary climb assist solution is required for short duration working.

In an event of a fall, the ALF Pulley locks on quickly to arrest the fall. As fall distances are extremely small, it is extremely unlikely that the user will be incapacitated. If necessary, a rescue can be easily organised from ground level.

The ALF has been field trialled 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 unit can be rigged in a continuous loop system, using a Large Single Prussik Pulley (Aluminium) [Part Code RP066].
