Cranes - General design - Part 3-1: Limit states and proof of competence of steel structures

This document specifies limit states, requirements and methods to prevent mechanical hazards in steel structures of cranes by design and theoretical proof of competence.
The significant hazardous situations and hazardous events that could result in risks to persons during intended use are identified in an informative Annex L (informative). Clauses 4 to 8 of this document provide requirements and methods to reduce or eliminate these risks:
a)   exceeding the limits of strength (yield, ultimate, fatigue);
b)   exceeding temperature limits of material or components;
c)   elastic instability of the crane or its parts (buckling, bulging).
This document does not apply to cranes which are designed before the date of its publication as EN.
NOTE   This document deals only with the limit state method in accordance with reference [44].

Dieses Dokument legt Grenzzustände, Anforderungen und Verfahren zur Vermeidung mechanischer Gefährdungen in Stahlkonstruktionen von Kranen durch Konstruktion und theoretischen Sicherheitsnachweis fest.
Die signifikanten Gefährdungssituationen und Gefährdungsereignisse, die zu Risiken für Personen während des bestimmungsgemäßen Gebrauchs führen könnten, sind in dem informativen Anhang L (informativ) angegeben. Die Abschnitte 4 bis 8 in diesem Dokument enthalten Anforderungen und Verfahren zur Reduzierung oder Eliminierung dieser Risiken:
n)   Überschreiten der Festigkeitsgrenzwerte (Fließen, Bruch, Ermüdung);
o)   Überschreiten der Temperaturgrenzwerte des Werkstoffs oder der Komponenten;
p)   elastische Instabilität des Krans oder seiner Teile (Knicken, Beulen).
Dieses Dokument gilt nicht für Krane, die vor dem Datum der Veröffentlichung dieses Dokuments als Europäische Norm gestaltet wurden.
ANMERKUNG   Dieses Dokument behandelt nur die Methode der Grenzzustände entsprechend dem Literaturhinweis [44].

Appareils de levage à charge suspendue - Conception générale - Partie 3-1: États-limites et vérification d'aptitude des structures en acier

Le présent document spécifie les états limites, les prescriptions et les méthodes pour prévenir les phénomènes dangereux mécaniques dans les structures en acier des appareils de levage à charge suspendue par la conception et la vérification d'aptitude théorique.
Les situations et phénomènes dangereux significatifs qui pourraient entraîner des risques pour les personnes lors de l'usage prévu sont identifiés à l'Annexe L (informative). Les Articles 4 à 8 du présent document fournissent des prescriptions et des méthodes visant à réduire ou éliminer ces risques :
a)   dépassement des limites de résistance (élasticité, rupture, fatigue) ;
b)   dépassement des limites de température du matériau ou des composants ;
c)   instabilité élastique de l’appareil de levage à charge suspendue ou de ses parties (flambage, voilement).
Le présent document ne s’applique pas aux appareils de levage à charge suspendue conçus avant sa date de publication en EN.
NOTE   Le présent document traite uniquement de la méthode des états limites conformément à la référence [44].
