Cranes - Manually controlled load manipulators
This document specifies requirements for manually controlled load manipulating cranes (herein referred to as manipulators), powered by an energy other than human energy, to assist an operator in the handling of loads.
This document does not cover:
- mechanically operated balancers that are based on springs, counterweights or automatons;
- manipulating robots;
- operation in severe conditions (e.g. extreme environmental conditions such as: freezer applications, high temperatures, corrosive environment, strong magnetic fields);
- operation subject to special rules;
- handling of loads the nature of which could lead to dangerous situations (e.g. molten metal, acids/alkalies, radiating materials, specially brittle loads);
NOTE High risk applications are dealt by EN 13135:2018 and EN 13001-2:2021.
- hazards occurring during construction, transportation, decommissioning and disposal.
This document does not cover hazards related to the lifting of persons.
The significant hazards covered by this document are identified in Annex A. For hazards that are not significant, EN ISO 12100:2010 applies.
This document is not applicable to manipulators manufactured before the date of its publication.
Krane - Handgeführte Manipulatoren
Dieses Dokument spezifiziert Anforderungen an handgeführte Manipulatoren (im Folgenden als Manipula-toren bezeichnet), angetrieben durch eine Energie, die nicht Menschenkraft ist, um einen Bediener bei der Handhabung von Lasten zu unterstützen.
Dieses Dokument behandelt nicht:
- mechanisch wirkende Balancer, die z. B. mit Federn, Gegengewichten oder Automaten arbeiten;
- Manipulationsroboter.
- den Betrieb unter erschwerten Bedingungen (z. B. extremen Umgebungsbedingungen wie Kühlhäuser, hohen Temperaturen, korrosiven Umgebungen, starken Magnetfeldern);
- Anwendungen, die durch besondere Vorschriften geregelt sind;
- die Handhabung von Lasten, deren Beschaffenheit Gefahrensituationen hervorrufen kann (z. B. Metall-schmelzen, Säuren/Laugen, radioaktive Stoffe, besonders bruchgefährdete Lasten);
ANMERKUNG Anwendungen mit hohem Risiko werden in EN 13135:2018 und EN 13001-2:2021 behandelt.
- Gefährdungen, die bei Errichtung, Transport, Außerbetriebnahme und Entsorgung auftreten.
Dieses Dokument behandelt nicht Gefährdungen im Zusammenhang mit dem Heben von Personen.
Die signifikanten Gefährdungen, die in diesem Dokument behandelt werden, sind in Anhang A benannt. Für nicht signifikante Gefährdungen ist EN ISO 12100:2010 anzuwenden.
Dieses Dokument gilt nicht für Manipulatoren, die vor dem Datum der Veröffentlichung dieses Dokuments hergestellt wurden.
Appareils de levage à charge suspendue - Manipulateurs de charge à contrôle manuel
Le présent document spécifie les exigences relatives aux appareils de levage de charge à contrôle manuel (ci-après dénommés manipulateurs), mus par une énergie autre que l’énergie humaine, destinés à assister un opérateur à manutentionner des charges.
Le présent document ne concerne pas :
- les équilibreurs actionnés mécaniquement utilisant par exemple des ressorts, des contrepoids ou des automates ;
- les robots manipulateurs ;
- le fonctionnement dans des conditions sévères (par exemple, des conditions environnementales extrêmes telles que : applications de congélation, températures élevées, environnement corrosif, champs magnétiques intenses) ;
- le fonctionnement soumis à des règles particulières ;
- la manutention de charges dont la nature pourrait générer des situations dangereuses (par exemple, métal en fusion, acides/bases, matériaux irradiants, charges particulièrement fragiles) ;
NOTE Les applications à haut risque sont traitées dans l’EN 13135:2018 et l’EN 13001-2:2021.
- les phénomènes dangereux qui surviennent lors de la fabrication, du transport, du déclassement et de la mise au rebut.
Le présent document ne traite pas des phénomènes dangereux liés au levage des personnes.
Les phénomènes dangereux significatifs traités par le présent document sont répertoriés dans l’Annexe A. Pour les phénomènes dangereux non significatifs, l’EN ISO 12100:2010 s’applique.
Le présent document ne s’applique pas aux manipulateurs fabriqués avant la date de sa publication.

This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 147.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.
This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.
