Steel static storage systems - Adjustable pallet racking - Tolerances, deformations and clearances
This European Standard specifies tolerances, deformations and 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 personnel, 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 acceptably low.
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 deformation limitations under loads.
The scope of this European Standard is limited to single deep adjustable beam pallet racking operated with industrial trucks or stacker cranes.
This European Standard specifically 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 for the safe operation of the overall system.
This European Standard shall be read in accordance with the latest guidance from the truck and stacker crane suppliers regarding turning radii, tolerances and deformations of the truck and stacker cranes.
Ortsfeste Regalsysteme aus Stahl - Verstellbare Palettenregale - Grenzabweichungen, Verformungen und Freiräume
Diese Europäische Norm legt Toleranzen, Verformungen und Freiräume/Zwischenräume fest, die bei Herstellung, Zusammenbau und Montage von Palettenregalen unter Beachtung der Wechselwirkung mit den Böden zu beachten sind. Diese Toleranzen, Verformungen und Freiräume sind wichtig, um die funktionellen Anforderungen zu erfüllen und eine geeignete Wechselwirkung mit den Regalbediengeräten sicherzustellen, für deren Bedienung qualifiziertes, kompetentes Personal eingesetzt wird, das eine Einweisung für das jeweilige Regalsystem erhalten hat. Die Wechselwirkungsbedingungen sind auch zur Bestimmung der Zuverlässigkeit des Lagersystems wichtig, damit ein nur geringes Risiko für Zusammenstöße mit Förderzeugen, Paletten oder für einen Zusammenbruch des Regalsystems besteht.
Diese Europäische Norm gibt Anleitungen zum Umgang mit einer Vielzahl von Problemen, zu denen Toleranzeinschränkungen für die betrieblichen Freiräume, für die Herstellung, für den Zusammenbau und für die Montage sowie Einschränkungen für die Verformung von Regalbauteilen unter Last durch Durchbiegung oder Dehnung gehören.
Der Anwendungsbereich dieser Europäischen Norm beschränkt sich auf verstellbare Palettenregale mit einfacher Tiefe, die mit Flur oder Regalförderzeugen bedient werden.
In dieser Europäischen Norm werden keine Toleranzen und Verformungen für Flur oder Regalförderzeuge erfasst. Hersteller/Lieferant und Kunde oder Benutzer des Flur oder Regalförderzeugs sind dafür verantwortlich, dass die in dieser Europäischen Norm für die Regalsysteme angegebenen Toleranzen, Verformungen und Freiräume für einen sicheren Betrieb des Gesamtsystems geeignet sind.
Diese Europäische Norm muss zusammen mit der neuesten Richtlinie durchgearbeitet werden, die vom Lieferanten der Flur oder Regalförderzeuge bezüglich Wenderadien, Toleranzen und Verformungen für die Förderzeuge zur Verfügung gestellt wird.
Systèmes de stockage statiques en acier - Rayonnages à palettes réglables - Tolérances, déformations et jeux
La présente Norme européenne spécifie les tolérances, déformations et jeux applicables dans le cadre de la production, de l'assemblage et de l'édification d'un rayonnage a palettes, y compris son interaction avec le sol. Ces tolérances, déformations et jeux sont des éléments importants eu égard aux exigences de fonctionnement et garantissent l'interaction du matériel de manutention utilisé par le personnel, formé et qualifié, en association avec le type particulier de systeme de rayonnage. Les conditions d'interaction sont également primordiales dans la détermination de la fiabilité du systeme de rayonnage. Il s'agit de limiter les risques de choc de chariot de manutention, de choc de palette ou de panne.
La présente Norme européenne donne des recommandations sur un large éventail de questions, notamment les limites de tolérance liées aux jeux, a la fabrication, a l'assemblage et a l'édification, ainsi que celles liées a la fleche ou a la déformation sous charge.
Le domaine d'application de la présente Norme européenne est limité aux systemes de rayonnage a palettes réglables actionnés par des chariots de manutention ou des ponts roulants gerbeurs.
La présente Norme européenne exclut spécifiquement les tolérances et déformations des chariots et ponts roulants gerbeurs. Il est de la responsabilité du fournisseur du chariot ou du pont roulant gerbeur, et de celle du client ou de l'utilisateur, de s'assurer que les tolérances, les déformations et les jeux sont acceptables dans le cadre d'un fonctionnement sécurisé de l'ensemble du systeme, comme le prévoit la présente Norme européenne.
La présente Norme européenne doit etre lue conformément aux dernieres recommandations des fournisseurs du chariot et du pont roulant gerbeur concernant les rayons de braquage, les tolérances et les déformations du chariot ou des ponts roulants gerbeurs.

EN 15620:2008 (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 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 specification, 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 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 equipment; 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. SIST EN 15620:2009
EN 15620:2008 (E) 7 1 Scope This European Standard specifies tolerances, deformations and 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 personnel, 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 acceptably 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 deformation 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 specifically 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 for 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 following referenced documents are indispensable for the application of this document.
