The Swift Lift Foot Anchor is hot forged from Manganese steel. The formed head provides spherical seating that the Lifting Eye engages, while a disc-shaped foot is embedded in the concrete. Due to its being a forged part, the Swift Lift Foot Anchor does not depend on welds or thread engagement to develop its safe working load. Forging provides maximum safety with its advantageous material structure. This allows the anchor to easily meet the OSHA requirement of a 4 to 1 factor of safety.In addition to the Manganese steel anchors, Type 304 or 316 Stainless Steel Swift Lift foot Anchors are available on special order. Use stainless steel anchors when maximum protection against corrosion is required.
