(Main)Cranes - General design - Part 3-5: Limit states and proof of competence of forged and cast hooks
Cranes - General design - Part 3-5: Limit states and proof of competence of forged and cast hooks
This document covers the following parts of hooks and types of hooks:
- bodies of any type of hooks made of steel forgings or steel castings, including stainless steel;
- machined shanks of hooks with a thread/nut suspension.
Plate hooks, which are those assembled of one or several parallel parts of rolled steel plates, are not covered.
The following is a list of significant hazardous situations and hazardous events that could result in risks to persons during normal use and foreseeable misuse. Clauses 4 to 8 of this document are intended to reduce or eliminate the risks associated with the following hazards:
a) exceeding the limits of yield strength, ultimate strength, fatigue strength, brittle fracture;
b) exceeding temperature limits of material.
This document is not applicable to hooks installed in cranes manufactured before the date of its publication and serves as a reference base for product standards for particular crane types.
This part of EN 13001 deals only with the limit state method in accordance with EN 13001-1:2015.
Krane - Konstruktion allgemein - Teil 3-5: Grenzzustände und Sicherheitsnachweis von geschmiedeten und gegossenen Haken
Dieses Dokument gilt für folgende Hakenteile und Hakenarten:
- alle Arten von geschmiedeten oder gegossenen Hakenkörpern aus Stahl, einschließlich Edelstahl;
- maschinell bearbeitete Hakenschäfte mit Gewinde/Mutter-Aufhängung.
Plattenhaken, d. h. Haken, die aus einem oder mehreren parallelen Teilen aus gewalzten Stahlplatten zusammengesetzt sind, fallen nicht darunter.
Im Folgenden sind signifikante Gefährdungssituationen und Gefährdungsereignisse aufgeführt, die bei normalem Gebrauch und vorhersehbarer Fehlanwendung zu Risiken für den Menschen führen könnten. Abschnitt 4 bis Abschnitt 8 dieses Dokuments sind notwendig, um Risiken, die mit nachfolgend genannten Gefährdungen verbunden sind, zu reduzieren oder zu beseitigen:
a) Überschreiten der Grenzwerte von Streckgrenze, Bruchfestigkeit, Ermüdungsfestigkeit, Sprödbruch;
b) Überschreiten der Temperaturgrenzwerte des Werkstoffs.
Dieses Dokument gilt für Haken, die in Kränen eingebaut sind, die nach dem Datum der Annahme dieser Europäischen Norm durch CEN hergestellt werden, und dient als Referenzgrundlage für Produktnormen bestimmter Krantypen.
Dieser Teil von EN 13001 befasst sich nur mit dem Grenzzustandsverfahren nach EN 13001-1:2015.
Appareils de levage à charge suspendue - Conception générale - Partie 3-5 : États limites et vérification des crochets forgés et moulés
Le présent document couvre les composants de crochets et types de crochets suivants :
- corps de tout type de crochets en acier forgé ou en acier moulé, incluant des aciers inoxydables ;
- tiges usinées de crochets à suspension par vis/écrou.
Les crochets lamellaires constitués de l’assemblage d’une ou de plusieurs tôles en acier laminé ne sont pas couverts.
La liste suivante spécifie les situations dangereuses et les évènements dangereux significatifs susceptibles d’entraîner des risques pour les personnes lors d’une utilisation normale ou d’une mauvaise utilisation prévisible. Les Articles 4 à 8 du présent document sont destinés à réduire ou éliminer les risques associés aux phénomènes dangereux suivants :
a) dépassement de la limite d’élasticité, de la résistance à la rupture, de la résistance à la fatigue, de la résistance à la rupture fragile ;
b) dépassement des limites de température du matériau.
Le présent document ne s’applique pas aux crochets installés sur des appareils de levage à charge suspendue construits avant la date de sa publication et sert de référence pour les normes produit des types particuliers d’appareils de levage à charge suspendue.
La présente partie de l’EN 13001 traite uniquement de la méthode des états limites selon l’EN 13001-1:2015.
