Hi,
Hopefully a simple question but google is not proving fruitful this morning. I have come across 2 sets of racking at site that have no SWL displayed. It is static racking and used to hold some bits with varying weight range. The prob is the racking is older than than majority of other type of racking at site and there is no documentation existing for this equipment. How do we identify the SWL for this racking? Is there a calculation that can be used to identify this or do we need to fully replace the racking with new equipt?
Cheers

Have you tried enquiring with racking inspection companies as those guys are experienced in the field and (hopefully) SEMA approved.
Try IRIS Ltd (other independant inspections companies available).
Worth a try anyway.

If the provenance of this racking cannot be ascertained, you are left with a few choices:
(a) determine the weight(s) of the items the racking used to hold and apply that as your SWL; or
(b) engage a suitably qualified engineer to do the calculations; or
(c) load it to failure with uniformly distributed weights until it fails, dispose of the racking you tested and then apply a factor of safety to any racking you have left (not really a goer that one!);
(d) buy new racking

There are structural engineering formulae that should make it possible to calculate the SWL--without destructive testing--but require engineering expertise to use them.
best bet is if you can trace the suppliers, otherwise use experts.

Hi Gavin
I work for SESS Ltd and will be able to offer you the service of calculating your load notices. However, to offer unbiased advice, whoever provides you with the safe working load information should have indemnity to protect you from any errors that may cause the rack to be overloaded. If they are supplying the information as a notice to be affixed to the rack that it is of the size, configuration and displays sufficient data so that it complies with the Storage Equipment Manufactures Association’s recommendations.
