Pallet Racking is a storage system utilising a series of frames consisting of two upright posts joined together by bolted or occasionally welded bracing members. The frames are connected by longitudinal members (beams) upon which regular shaped pallet loads are placed. Where loads are irregular by virtue of their length, depth or general variability then Cantilever Racking is often used. This benefits from having no regularly spaced frames obstructing long products being placed into the rack.
Often the inspection of Pallet Racks reveals 'Red Risks' which require immediate offloading of those racks or locations, Red Risks include the following :
POST DAMAGE
For an upright bent in the direction of the rack beam, the maximum gap between the upright and the straight edge should not exceed 5.0mm. If it does it becomes an ORANGE risk. More than 10mm is RED risk.
RED RISK REQUIRES IMMEDIATE OFFLOADING AND REPAIRING/REPLACING
BRACE DAMAGE
For bracing members bent in either plan, the gap between straight edges and bracing member should not exceed 10.0mm. If it does it becomes an ORANGE risk. More than 20mm is RED risk.
ORANGE RISK BECOMES A RED RISK IF NOT REPAIRED/REPLACED WITHIN 4-6 WEEKS.
BEAM DAMAGE
Beams will naturally deflect under normal loading conditions to a maximum permissible span/200. Residual deflection should be no more than 20% of normal deflection under load.
BEAM DISLODGEMENT
If connector lugs are dislodged or not seated correctly, the beam will fail at one end leading to collapse of the level or the bay OR even the whole rack.
If these potential risks aren't closely monitored ... watch out it may be too late!
