ABSTRACT:
In one aspect of the invention, a vacuum anchor assembly for anchoring a fall protection system to a surface of an anchorage structure comprises an anchor member having an air input connector, a venturi, and a seal member incorporated into the anchor member. The air input connector is configured and arranged to receive air from a pressurized air source. The venturi is in fluid communication with the air input connector and is configured and arranged to receive air and create a vacuum therefrom. The seal member is in fluid communication with the venturi and is configured and arranged to receive the vacuum and resulting suction and create a seal between the anchor member and the surface of the anchorage structure sufficient to operatively connect the anchor member to the surface of the anchorage structure with the vacuum and resulting suction created within the anchor member.
