29、08 (E) 6 Introduction The determination of the safe load bearing capacity of racking is a structural issue and therefore the Eurocodes are relevant, especially EN 1993. The most relevant parts for racking are EN 1993-1-1 and EN 1993-1-3. In order to have reliable state of the art guidance for those
30、involved in designing these products and due to the differences in the shape of the structural components, detailing and connection types, additional technical information to the Eurocodes is required. The scope of CEN/TC 344 is to establish European Standards providing guidance for the specificatio
31、n, design, methods of installation, accuracy of build and also guidance for the user on the safe use of steel static storage systems. This, together with the need for harmonised design rules, was the reason that the European Racking Federation (ERF) has taken the initiative for the CEN/TC 344. This
32、TC is in the course of preparing a series of European Standards regarding Steel static storage systems as follows: prEN 15512, Steel static storage systems Adjustable pallet racking systems Principles for structural design; prEN 15629, Steel static storage systems The specification of storage equipm
33、ent; prEN 15635, Steel static storage systems The application and maintenance of storage equipment. The intention is for these EN series to be published sequentially over a period of ten years. BS EN 15620:2008EN 15620:2008 (E) 7 1 Scope This European Standard specifies tolerances, deformations and
34、clearances that pertain to the production, assembly and erection of pallet racking including the interaction with floors. These tolerances, deformations and clearances are important in relation to the functional requirements and ensuring the proper interaction of the handling equipment used by perso
35、nnel, trained and qualified as competent, in association with the specific type of racking system. The interaction conditions are also important in determining the reliability of the storage system to ensure that the chance of an industrial truck impact, pallet impact or a system breakdown is accept
36、ably low. The design safety philosophy given in prEN 15512 is based upon compliance with this standard. This European Standard gives guidance for a variety of issues including operating clearances, manufacturing, assembly and erection tolerance limitations, as well as deflection or strain deformatio
37、n limitations under loads. This European Standard is limited to single deep adjustable beam pallet racking operated with industrial trucks or stacker cranes. Drive-in, double deep and satellite systems will be considered for inclusion in the document in the future. This European Standard specificall
38、y excludes the tolerances and deformation of the trucks and stacker cranes. It is the responsibility of the truck or stacker crane supplier and the client or user to ensure that the tolerances, deformations and clearances, as quoted in this European Standard for the racking systems, are acceptable f
39、or the safe operation of the overall system. This European Standard gives guidance to be used in conjunction with the latest information from the truck and stacker crane suppliers regarding turning radii, tolerances and deformations of the truck and stacker cranes. 2 Normative references The followi
