Cranes - Light crane systems

This document applies to:
-   light crane systems, either suspended or free-standing systems, where the rated capacity of any single lifting device is 4 t or less;
-   pillar and wall-mounted jib cranes, without an operator's cabin, whose rated capacity is 10 t or less and whose overturning load moment is 500 kNm or less.
NOTE   For illustration of crane types, see Annex B.
This document is not applicable to cranes covered by another product specific crane standard, e.g. EN 15011:2011+A1:2014 or EN 14985:2012.
This document is applicable to cranes and crane systems, whose structures are made of steel or aluminium, excluding aluminium structures containing welded joints.
This document gives requirements for all significant hazards, hazardous situations and events relevant to cranes, when used as intended and under conditions foreseen by the manufacturer (see Clause 4).
The specific hazards due to potentially explosive atmospheres, ionizing radiation, operation in electro-magnetic fields beyond the range of EN 61000 6 2:2016 and operation in pharmacy or food industry are not covered by this document.
This document does not cover hazards related to the lifting of persons.
This document is applicable to cranes, which are manufactured after the date of its publication by CEN as a European Standard.
This document is not applicable to cranes manufactured before the date of its publication.

Krane - Leichtkransysteme

!Dieses Dokument gilt für:
- Leichtkransysteme, entweder hängende oder freistehende Systeme, bei denen die Nennkapazität einer einzelnen Hebevorrichtung 4 t oder weniger beträgt;
- Säulenschwenkkrane und Wandschwenkkrane ohne Fahrerkabine mit einer Nennkapazität von 10 t oder weniger und einem umkippbaren Lastmoment von 500 kNm oder weniger.
ANMERKUNG   Zur Veranschaulichung der Kranarten, siehe Anhang B.
Dieses Dokument gilt nicht für Krane, die unter eine andere produktspezifische Norm für Krane fallen, z. B. EN 15011:2011+A1:2014 oder EN 14985:2012.
Dieses Dokument gilt für Krane und Kransysteme, deren Strukturen aus Stahl oder Aluminium bestehen, ausgenommen Aluminiumkonstruktionen mit geschweißten Verbindungsstellen.
Dieses Dokument enthält Anforderungen für alle wesentlichen Gefährdungen, Gefährdungssituationen und Gefährdungsereignisse, die für Krane relevant sind, wenn sie bestimmungsgemäß und unter vom Hersteller vorgesehenen Bedingungen verwendet werden (siehe Abschnitt 4).
Die spezifischen Gefährdungen durch explosionsgefährdete Bereiche, ionisierende Strahlung, Betrieb in elektromagnetischen Feldern außerhalb des Anwendungsbereichs von EN 61000 6 2:2016 und der Betrieb in der Pharma- oder Lebensmittelindustrie werden von diesem Dokument nicht abgedeckt.
Dieses Dokument enthält keine Anforderungen an das Heben von Personen.
Dieses Dokument gilt für Krane, die nach dem Datum der Veröffentlichung dieses Dokuments als Europäische Norm durch CEN hergestellt werden.
Dieses Dokument gilt nicht für Krane, die vor dem Veröffentlichungsdatum dieses Dokuments hergestellt wurden."
