DEHA HD-SOCKET LIFTING SYSTEM - Alcor SA

SAFETYSAFETY REGULATIONS OF THE MAIN GERMAN INDUSTRIAL EMPLOYERS’ LIABILITY INSURANCEASSOCIATION FOR LIFTING ANCHORS AND LIFTING ANCHOR SYSTEMS FOR PRECAST CONCRETEELEMENTS ZH 1/17These safety regulations apply toseries manufactured lifting anchors andlifting anchor systems for transportingprecast concrete elements with liftingequipment. Under these regulations,lifting anchor systems are defined as assemblagesconsisting of the componentwhich is permanently anchored in theprecast concrete element (lifting anchor)and the load-bearing component whichis temporarily attached for lifting purposes.Lifting anchors and lifting anchorsystems must be manufactured in sucha way that, when used properly, theyensure that the precast element is liftedsafely.Load lifting deviceAngle of liftβSuspension deviceLifting tackleLifting attachmentLoadLiftinganchorHD-Lifting SystemLABELLINGINSTALLATION AND APPLICATIONAll HD-Lifting Anchors and lifting attachmentsare clearly marked for thebenefit of the user. According to thesafety regulations for lifting anchor systems,the identification markings mustalso be clearly visible after installation.This requirement is fulfilled by the preassembledsocket protector systemwhich is clearly marked.SAFETY FACTORSThe components in the HD-LiftingAnchor System is designed with a safetyfactor of at least 3 against steel failure.The load limits given in the tables havea safety factor of at least 2.5 againstconcrete failure. Note, however thatall loads must be factored as shown onpage 9.The HD-Socket Lifting System must onlybe installed in accordance with the followingtechnical instructions.Combining components of the systemwith those of other manufacturers isnot permitted. Re-using lifting anchorsis not permitted. Repeated lifting whenlifting and installing the precast elementis not considered as re-use. For liftinganchors which are intended for longterm use, such as crane ballast kentledgeand cover slabs, the sockets mustbe manufactured from stainless steel, inaccordance with the approval certificatefor “Stainless steels”, Approval No.Z- 30.3-6. Incorrectly installed liftinganchors, or lifting anchors which havedamaged components, such as corrosionor visible deformation, must not be usedfor lifting purposes.The Installation instructions for the differentsystems must be available at thepoint where the anchor system is beingused, i.e. at the precast yard and on theconstruction site. Production managementand site management must ensurethat personnel are aware of and haveunderstood the installation and generalsafety regulations.QUALITY CONTROLAll required testing of lifting anchorsand lifting attachments is carried outas part of the internal qualityassurance system operated byHALFEN-DEHA which complieswith DIN ISO 9001/2000.8
