Common FAQs - Load Notices
Different Beam Configurationsback to list
24 April 2020
Q. I have a query in relation to load notices that I hope you could assist with. In our racking we have different beam length configurations i.e. 3300mm, 2700mm & 2300mm lengths. What is the best way to convey this on the SEMA load notice? How should the Maximum Bay Load be calculated given there are different configurations within the levels of racking?
A. Information on the load notice is not restricted to the Safe Working Load (SWL) of the racking; there are also important instructions and information about the general usage of the racking e.g. prohibitions about altering or climbing the racking as well as an instruction to report damage and signposts to information sources.
The purpose of the load notice is to provide sufficient information to the users to allow them to use equipment safely.
Responsibility for the data on a Load Notice lies with the provider of the load notice (based on the racking layout at the time of providing the sign).
Safe working load capacity is calculated according to the racking design code e.g. the SEMA Code of practice for the design of adjustable pallet racking https://www.sema.org.uk/codes-of-practice/publications/more/8337/page/1/code-of-practice-for-the-design-of-adjustable-pallet-racking or other codes such as EN15512. This is a complex task that requires test data for the racking system concerned as well as the application of structural engineering theory and should normally be entrusted to a skilled and qualified Structural Engineer. As such is is normally a task that is undertaken by the racking manufacturer or supplier.
If you have racking with different configurations then this information could be transmitted by providing a different load notice for each configuration or, alternatively, by using a load notice that gave an acceptable solution for all the configurations - what an engineer might call a “conservative” or “lower-bound solution”. You should contact your supplier to discuss the best solution for your particular case.
