Rapid Lift System
Based on a steel anchor, capable of lifting loads up to 26 tonnes per anchor, which is cast into the concrete with a recess-former over the head. After casting, the anchor is below the concrete surface but the anchor hole is accessible, allowing a ring clutch lifting hook to be placed over it and locked by hand. After use the clutch can be easily released. Release under load is not possible.
Consult with Halfen’s technical literature for details. A load calculation programme is also available to download from www.halfen.com or on CD-ROM to assist in selection.
It is recommended that Halfen be consulted early in the design process.

Other requirements: Cast-in lifting points for precast units.
