Eurocode 3 - Design of steel structures - Part 6: Crane supporting structures

Edition date: 2026-03-18
In Force
Available languages: English
Summary: 1.1 Scope of EN 1993-6 (1) EN 1993-6 provides rules for structural design of crane supporting structures. (2) EN 1993-6 is applicable to crane supporting structures, especially to indoor and outdoor overhead crane runway beams, of: a) overhead travelling cranes, either: — top-mounted cranes; — underslung cranes; b) monorail hoist blocks. NOTE The principles of the design rules can be applied to supporting structures of other types of cranes making due allowance for differences in the crane-induced actions, if exist. For example, the design rules for supporting structures of the cranes listed in (2) assume that the horizontal crane loads occur randomly scattered along the runways in general. This assumption does not apply to other cranes such as travelling wall jib cranes. (3) EN 1993-6 does not apply to the tracks and suspensions of light crane systems conforming to EN 16851, see Figure 1.1. NOTE The standardized tracks and suspensions of light crane systems are considered as parts of the crane. [Figure 1.1 — Light crane system] (4) Additional rules are given for ancillary runway items including crane rails, structural end stops, surge connectors and surge girders and for runway supporting structures. (5) EN 1993-6 does not apply to cranes and all other moving parts. NOTE Provisions for cranes are given in EN 13001 (all parts) in general and for bridge and gantry cranes in EN 15011 in particular. 1.2 Assumptions (1) Unless specifically stated, EN 1990-1, EN 1991 (all parts) and EN 1993-1 (all parts) apply. (2) The design methods given in EN 1993-6 are applicable if — the execution quality and tolerances are as specified in EN 1090-2, and; — the construction materials and products used are as specified in the relevant parts of EN 1993, or in the relevant material and product specifications. (3) Following interfaces between hoisting device and its supporting structure are assumed: a) the top of crane rail for top-mounted cranes; b) the top of flange on which the crane or hoist block operates for underslung cranes and monorail hoist blocks; c) the support points as shown in Figure 1.1 for light crane systems.

1.1 Domaine d'application de l’EN 1993 6 (1) L'EN 1993 6 fournit des règles pour le calcul des structures supportant des appareils de levage. (2) L'EN 1993 6 est applicable aux structures supportant des appareils de levage, en particulier aux poutres de roulement des appareils de levage intérieurs et extérieurs pour : a) les ponts roulants : — ponts roulants posés ; — ponts roulants suspendus ; b) les chariots-palan monorails. NOTE Les principes des règles de calcul peuvent être appliqués aux structures supportant d'autres types de ponts roulants, en tenant compte des différences existant, le cas échéant, dans les actions induites par l'appareil de levage. Par exemple, les règles de calcul des structures supportant les appareils de levage énumérées en (2) supposent que les charges horizontales de l'appareil de levage sont généralement exercées de manière aléatoire le long des chemins de roulement. Cette hypothèse ne s'applique pas à d'autres types d'appareils de levage, tels que les potences murales. (3) L'EN 1993 6 ne s'applique pas aux voies de roulement et aux éléments de suspensions des systèmes de grues légères relevant de l'EN 16851, voir la Figure 1.1. NOTE Les voies de roulement et les suspensions standardisées des systèmes de grues légères sont considérées comme faisant partie de l'appareil de levage. [...]

1.1 Anwendungsbereich von EN 1993 6 (1) EN 1993 6 enthält Regeln für die Tragwerksbemessung von Kranunterstützungen. (2) EN 1993 6 ist anwendbar für die Kranunterstützungen, insbesondere für Kranbahnträger innerhalb und außerhalb von Gebäuden von: a) Brückenlaufkranen, entweder: - Laufkrane; - Hängekrane; b) Einschienenkatzen. ANMERKUNG Die Grundsätze der Bemessungsregeln können auf die Unterstützungskonstruktionen anderer Kranarten angewendet werden, wobei gegebenenfalls die Unterschiede in den Einwirkungen aus dem Kranbetrieb zu berücksichtigen sind. Beispielsweise wird in den Bemessungsregeln für die Unterstützungskonstruktionen Kranunterstützungen der in (2) aufgeführten Kranarten vorausgesetzt, dass die horizontalen Kranlasten im Allgemeinen zufällig entlang der Kranbahnen verteilt auftreten. Diese Voraussetzung gilt nicht für andere Krane, wie z. B. Wandlaufkrane. (3) EN 1993 6 ist nicht für die Schienen und Aufhängungen von Leichtkransystemen nach EN 16851 anwendbar, siehe Bild 1.1. ANMERKUNG Die genormten Schienen und Aufhängungen von Leichtkransystemen werden als Teil des Krans verstanden. Legende 1 nach EN 1993 (Normenreihe) bemessener Unterstützungsträger 2 standardisierte Schiene eines nach EN 16851 bemessenen Leichtkransystems 3 Auflagerpunkt Bild 1.1 — Leichtkransystem (4) Zusätzlich werden Regeln für Zubehörteile von Kranbahnen einschließlich Kranschienen, bauliche Fahrbahnendbegrenzungen, Horizontalhalterungen und Horizontalträger und für die Kranbahnunterstützung angegeben. (5) EN 1993 6 gilt nicht für Krane und alle anderen beweglichen Teile. ANMERKUNG Bestimmungen für Krane sind in der Normenreihe EN 13001 im Allgemeinen und für Brücken- und Portalkrane in EN 15011 im Besonderen angegeben. 1.2 Annahmen (1) Sofern nicht ausdrücklich etwas anderes angegeben ist, gelten EN 1990, Normenreihe EN 1991 und Normenreihe EN 1993 1. (2) Die in EN 1993 6 angegebenen Bemessungsverfahren sind anwendbar, wenn - die Qualität der Ausführung und die Toleranzen den Festlegungen von EN 1090 2 entsprechen, und - die verwendeten Baustoffe und -produkte den Festlegungen der zutreffenden Teile von EN 1993 oder den zutreffenden Material- und Produktspezifikationen entsprechen. (3) Es werden die folgenden Schnittstellen zwischen den Hebezeugen und deren Unterstützung angenommen: a) die Oberkante der Kranschiene für Laufkrane; b) die Oberseite des Flansches, auf dem der Kran oder die Laufkatze im Fall von Hängekranen und Einschienenkatzen läuft; c) die in Bild 1.1 für Leichtkransysteme gezeigten Auflagerpunkte.
