TILT-UP CONSTRUCTION - Brock White

Ground Release IISystemT-43-L Ground ReleaseII Lifting HardwareOur NEW T-43-L Ground ReleaseII Lifting Hardware unit offers you, the tilt-up contractor, the latest and easiest to use tilt-uplifting hardware unit on the market today! This new lifting hardware unit is a simplified design and when combined with ourT-41 Ground ReleaseII Insert provides you with a superior system for the quick and efficient erection of tilt-up concrete wallpanels.• Bail will accept all conventional crane attachments. Unitmoves easily as it follows line of action of crane cable.Lifting SystemsCoil InsertsRelease ArmRelease LineBailLifting Body• Lifting Body attaches to head of insert. Whenever diagonalloads are applied to the bail, the result is a combinationof a compressive load applied to the concrete and atension load applied to the insert.• Release Line is a 1/2” hollow braided Polyethylene Cordof sufficient length to reach the ground.• SWL is 15,000 Ibs. with an approximate factor of safetyof 5 to 1.Minimum Insert Distances15"Minimum15" Minimum10 oMaximum15’15" MinimumT-4115"T-49 GroundMinimumGyro Release TiltPlus System6" Minimum 6" MinimumLedger Ledger or orProjection Projection15" 15"Minimum MinimumWarning! Inserts must be properly located in relation to the centerof gravity of the panel. This work should be performed under thedirection of a registered professional engineer.Ledger Ledger or orProjection Projection6" Minimum 6" MinimumSafety Notes:Safe use of the Ground Release II System requires theinserts to be positioned so that the arrows on thedirection label point to the top and bottom of the panel(parallel to the sides of the panel).The inserts must be properly located in relation to edges,corners, openings and ledgers, and at distances allowingthe development of a full concrete shear cone. Minimumdistances are shown in the sketches above. Placing aninsert closer to an edge than the minimums shown mayreduce the effective concrete shear cone and reduce theinsert’s safe working load.Lifting inserts must be properly wired in place sothat the vertical axis of the insert is perpendicular tothe panel surface. Care must be taken to avoiddisplacement of the inserts during concreteplacement and screeding operations.Do not weld to a lifting insert. Welding causesembrittlement and can result in an insert failure.See related safety information concerning weldingon inside front cover.34 04-09
