The RGA4 is a three way retrieval block fitted with an up/down winch mechanism and the standard fall arrest capability.

In the event of a fall, the operative can be winched up or down to safety.
The RGA4 can raise the operative to a safe area if the area below is unsuitable.
The man-riding winch function is for use only as a rescue provision – NOT for access/egress.
This must be backed up with a separate fall arrest system, and a rescue provision that is also separate to the winch.
