What has happened… a worker has fallen from his working platform. The worker condition is good enough where he is able to assist in his own recovery and rescue.
This video was developed over a span of time where Rich took to heart, the process of confined space rescue, fallen worker rescue and simply using what you have on your belt. The Fast Fours concept is evolving over time and even now… modifications have taken place to make this system smaller and more compact.
Fast Fours Mechanical Advantage System
The Fast Fours is a simple variation on a standard set-of-fours. The difference is that the far end of the rope is not terminated on the becket of a pulley. Instead it is run through another progress capture pulley. This means that an operator can either pull on both ends simultaneously to yield a fast take up 2:1 or a single strand for a 4:1.
There is another unique advantage of this system for fallen worker and confined space recovery. If capable, the fallen worker can pull on one end of the system while the rescuer pulls on the other which speeds the recovery, halves the individual work, and involves the victim in the task.
