ABSTRACT:
A rigging system for retrieving a worker in the event of the collapse or tearing of a peripheral panel of an air-supported fabric roof employs one or more endless cables each entrained over pulleys located at the edge of the roof and inwardly therefrom. The worker is connected to one run of the cable by a safety line and harness. In the event of an accident, the cables are driven, for example by a detachable motor rotating one of the pulleys, to move the worker to the vicinity of the peripheral wall.
