We were approached by a manufacturing company in Ipswich who required a fresh approach to their yearly rack inspection. Due to the high volume of pallet movement, they asked for the inspection to be carried out on a Friday (quietest time). Our SEMA Approved Rack Inspector visited site on the next available Friday. Below are what we found.
SPECIFICATION
The original manufacturer of the onsite storage equipment is Hi Lo, Link 51, Dexion, Constructor, AR Sistemas & PSS.
We are unable to confirm if the equipment was supplied in new or used condition. No locations display a clear numbering/identification system, we have logically numbered and provided a layout that has been used in this report for collation in Appendix A of this report.

PALLETS
During the inspection several pallet loads were noted for concern, pallets should be of a suitable quality with the load upon them centralised and seated squarely. Any pallets found to have uneven loads upon them may unduly stress the pallet and effect the Uniformly Distributed Loading on the beams. Uneven loads stored within the racks are at an increased risk of becoming dislodged or collapsing within the system or when being loaded/retrieved from the racking of which may result in racking damages and collapses. We would advise that MHE operatives on site be made aware of the correct loading requirements of goods upon pallets as well as a visual pallet check before it is loaded into the racking system.
MODIFICATIONS
It was observed that several beams have been cut, resized and rewelded at the connector, this is not a manufacture approved practise their welds are strictly controlled and tested under factory conditions and therefore any original manufacturer loadings cannot be guaranteed to the main load bearing component, this modification could result in beam failure. If the alteration has been carried out by a ‘Coded Welder; then certification and assurance must be gained in writing with liability on the welder/company, if this cannot be ascertained the beam is rendered as undermining structural performance and safety and therefore not fit for purpose within the racking system. If the beam remains in use, then the liability must sit with your company along with any repercussions. We strongly recommend that the beams be replaced for original manufacture suitable for the loads being imposed.
INCORRECT COMPONENTS
Dexion Mk3 frames splices were noted to be of a suspected incorrect configuration and by use of non-manufacturer aftermarket splice kits. We would generally expect to find spacers within the splice/upright to ensure that upright sections do not become deformed. We would advise that the racking manufacturer be consulted to offer further guidance on this and to ensure both structural integrity and compliance is being adhered to in the rack’s current configurations.
