RALF – rescue auto locking fall arrest system

Description

RALF (Rescue Auto Locking Fall Arrest System pulley) can be set up with a combination of prussik pulleys to create a 3:1 or 5:1 mechanical advantage with virtually any length of rope to create a simple hauling system for one or two person loads. If at any point during lifting or lowering the user loses control the overspeed brake will lock, arresting a fall within inches. The locking mechanism is not set up to be a one-use system and therefore does not have to be serviced after every fall arrest, however a thorough inspection of the rope and device will be required as well as a six-monthly thorough inspection and whatever replacement parts are required at that time.
