Technical InformationPackaging and HandlingThe correct packaging, transport, storage and handling ofcable assemblies is critical to ensure that the customerreceives the product in first class condition. For specificadvice on all aspects of strand lifting and handling,particularly where safety is a concern, contact Bridon.Cable assemblies are normally supplied in coils or on reels.To avoid possible wire displacement in the strand, Bridonrecommend the following minimum coil diameters:Locked Coil StrandSpiral Strand30 x strand diameter24 x strand diameterCoils can be wrapped in polyweave plastic to preventcontamination from foreign bodies such as dust, sand etc.It is usual for fitted sockets to protrude outside thecircumference of the coiled strand. The sockets can bewrapped to protect against mechanical damage duringtransit. Smaller diameter coils can be stacked and shrinkwrapped on enclosed wooden pallets for added protection.CoilLong length cable assemblies can be transported onindividually designed reels. Wooden reels are used forpiece weights up to approximately 10 tonnes, thereaftersteel reels are used. The fitted sockets are contained withinthe reel in special compartments. For additional protectionfrom contamination and damage during transit, the cablecan be wrapped in polyweave plastic and the outercircumference of the reel can be lagged with timbers.Transport and storage guidelinesDuring lifting, always use a minimum of three equidistantlypositioned soft slings of sufficient length to avoid deformingthe coil. When stacking coils, either during transportation orfor storage, always use adequate wood dunnage. Reels aregenerally lifted by means of a centre shaft. For long termstorage of cables, always ensure protection fromatmospheric influences but maintain adequate ventilation toavoid the build up of condensation. Avoid direct contactwith the floor and ensure there is a flow of air under thestrand.ReelOn site handling recommendationsCoiled strands require special care when handling and mustbe placed on a rotating braked pay-off stand. The cableassembly should then be pulled off horizontally – pulling thecable vertically will create a corkscrew effect and damagethe product. For cable assemblies supplied on reels asuitably braked stand should be used.Transport by roadWhen handling cable assemblies we recommend thefollowing:• Observe the cable at all times, do not allow it tokink, twist or be pulled over sharp edges• Maintain a bend radius of at least 15 times thecable diameter for locked coil and 12 times thecable diameter for spiral strand• Avoid damaging the zinc coating• Always remove any seizing wires after installationTransport by air38BRIDON Structural Systems
