ANMERKUNG 1 Besondere Anforderungen für spezielle Krantypen sind in der zugehörigen Technischen Spezifikation für
den speziellen Krantyp angegeben.
Im Folgenden ist eine Auflistung von wichtigen gefährlichen Situationen und gefährlichen Ereignissen gegeben, die
Risiken für Personen während des normalen Gebrauchs (des Krans) und vorhersehbaren Missbrauchs zur Folge
haben könnten. Abschnitte 5 und 6 dieser Spezifikation sind erforderlich, um mit folgenden Gefahren verbundene
Risiken zu reduzieren oder zu eliminieren:
Überschreitung der Festigkeitsgrenzwerte.
Diese Technische Spezifikation gilt für Krane, die nach dem Datum der Genehmigung durch CEN hergestellt
werden, und dient als Referenzgrundlage für die Technische Spezifikation für spezielle Krantypen.
ANMERKUNG 2 CEN/TS 13001-3-2 berücksichtigt nur die Methode der Grenzzustände nach EN 13001-1.

Appareils de levage à charge suspendue - Conception générale - Partie 3-2 : États limites et vérification d'aptitude des systèmes de mouflage

La présente partie 3-2 de la Spécification Technique EN 13001 est à utiliser conjointement avec les parties 1 et 2 pour spécifier les conditions, prescriptions et méthodes générales permettant, par la conception et la vérification théorique, d'éviter les risques mécaniques dus aux systèmes de mouflage d'appareils de levage à charge suspendue.
NOTE 1   Les prescriptions spécifiques relatives aux types particuliers d'appareils de levage à charge suspendue sont données dans la Spécification Technique appropriée au type particulier d'appareil de levage à charge suspendue.
La liste suivante énumère les situations et les événements dangereux significatifs susceptibles d'entraîner des risques pour les personnes lors d'une utilisation normale ou d'une mauvaise utilisation prévisible. Les Articles 5 à 6 de la présente norme sont nécessaires pour réduire ou éliminer les risques associés au phénomène dangereux suivant :
Dépassement des limites de résistance.
La présente Spécification Technique s'applique aux appareils de levage à charge suspendue construits après la date d'approbation par le CEN de la présente norme, et sert de référence pour les spécifications techniques de types particuliers d'appareils de levage à charge suspendue.
NOTE 2   Le CEN/TS 13001-3-2 traite uniquement de la méthode des états limites selon l'EN 13001-1.
