(Main)Cranes - Power driven winches and hoists - Part 2: Power driven hoists
Cranes - Power driven winches and hoists - Part 2: Power driven hoists
This European Standard is applicable to the design, information for use, maintenance and testing of power driven hoists with or without trolleys for which the prime mover is an electric, hydraulic or pneumatic motor. They are designed for the lifting and lowering of loads which are suspended on hooks or other load lifting attachments. Hoists can be used either in cranes, in other machines, e.g. rail dependent storage and retrieval equipment, monorail conveyors or by itself.
This European Standard is applicable to the following types of hoist:
a) rope hoist;
b) chain hoist;
c) belt hoist, except belt hoist with steel belts as hoisting media;
d) open type hoist;
e) NGL building hoists including supporting structures.
This European Standard is not applicable of the following hazards:
i) this European Standard does not cover hazards related to builders hoists for the transport of goods as defined in 2000/14/EC;
ii) this European Standard does not cover hazards related to the lifting of persons.
NOTE The use of hoists for the lifting of persons may be subject to specific national regulations.
This European Standard does not specify additional requirements for hazards related to the use of hoists in explosive atmospheres in underground works.
The significant hazards covered by this European Standard are identified in Clause 4.
This document is not applicable to power driven hoists which are manufactured before the date of publication of this European Standard by CEN.
Krane - Kraftgetriebene Winden und Hubwerke - Teil 2: Kraftgetriebene Hubwerke
Diese Europäische Norm gilt für die Konstruktion, Betriebsanleitung, Wartung und Prüfung von kraftge-triebenen Hubwerken mit oder ohne Fahrwerke, deren Hauptantriebselement ein elektrischer, hydraulischer oder pneumatischer Motor ist. Sie sind für das Heben und Senken von an Haken oder anderen Lastaufnahmemitteln hängenden Lasten konstruiert. Hubwerke können entweder in Kranen, in anderen Maschinen, z. B. Regalbediengeräten, Einschienenbahnen oder für sich selbst verwendet werden.
Diese Europäische Norm gilt für die folgenden Hubwerkstypen:
a) Seilzug;
b) Kettenzug;
c) Bandzug, ausgenommen Bandzüge mit Stahlbändern als Tragmittel;
d) offenes Hubwerk;
e) Bauaufzüge für nicht geführte Lasten einschließlich Tragkonstruktionen.
Diese Europäische Norm umfasst nicht die folgenden Gefährdungen:
a) Diese Europäische Norm erfasst nicht Gefährdungen durch Bauaufzüge für den Transport von Gütern wie in 2000/14/EG definiert;
b) Diese Europäische Norm erfasst nicht Gefährdungen beim Heben von Personen.
ANMERKUNG Die Verwendung von Hubwerken für das Heben von Personen kann spezifischen nationalen Vorschriften unterliegen.
Diese Europäische Norm spezifiziert keine zusätzlichen Anforderungen für Gefährdungen hinsichtlich des Einsatzes von Hubwerken in explosionsfähigen Atmosphären im Bergbau.
Die von dieser Europäischen Norm erfassten signifikanten Gefährdungen sind in Abschnitt 4 identifiziert.
Dieses Dokument gilt nicht für kraftgetriebene Hubwerke, die vor dem Datum der Veröffentlichung dieses Dokuments durch CEN gebaut wurden.
Appareils de levage a charge suspendue - Treuils et palans motorisés - Partie 2: Palans motorisés
La présente Norme européenne s’applique a la conception, l’information pour l’utilisation, la maintenance et les essais relatifs aux palans motorisés avec ou sans chariot, dont le moteur principal est électrique, hydraulique ou pneumatique. Ces palans sont conçus pour le levage et la descente des charges suspendues a des crochets ou autres dispositifs de préhension. Les palans peuvent etre utilisés dans les appareils de levage a charge suspendue, dans d’autres machines, par exemple, transtockeurs, transporteurs monorails, ou de maniere autonome.
La présente Norme européenne s’applique aux types de palan suivants :
a) palan a câble ;
b) palan a chaîne ;
c) palan a sangle, a l’exception des palans a sangle avec des sangles métalliques utilisées comme matériel de levage ;
d) palan ouvert ;
e) treuil potence de chantier, y compris les structures d’appui.
La présente Norme européenne ne s’applique pas aux phénomenes dangereux suivants :
i) la présente Norme européenne ne couvre pas les phénomenes dangereux relatifs aux treuils de chantier utilisés pour le transport des biens tels que définis dans la Directive 2000/14/CE ;
ii) la présente Norme européenne ne couvre pas les phénomenes dangereux relatifs au levage de personnes.
NOTE L’utilisation de palans pour le levage des personnes peut faire l’objet de réglementations nationales spécifiques.
La présente Norme européenne ne spécifie pas de prescriptions supplémentaires pour les phénomenes dangereux relatifs a l’utilisation des palans en atmospheres explosible dans le cas de travaux en sous-sol.
Les phénomenes dangereux significatifs couverts par la présente Norme européenne sont identifiés a l’Article 4.
La présente Norme européenne s’applique aux palans motorisés fabriqués apres la date d’approbation de la présente norme par le CEN.
