NOTE 2 The use in public road traffic is governed by the national regulations.
1.2 This document deals with all significant hazards, hazardous situations and events relevant to truck mixers when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex D). This document specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards during transportation, assembly, dismantling, disabling, scrapping, operation and maintenance of the truck mixer.
1.3 This document is not applicable to machines which are manufactured before the date of publication of this document by CEN.

ANMERKUNG 2 Die Verwendung im öffentlichen Straßenverkehr unterliegt nationalen Regelungen.
1.2 Dieses Dokument behandelt alle signifikanten Gefährdungen, Gefährdungssituationen und Gefährdungsereignisse, die auf Fahrmischer zutreffen, wenn sie bestimmungsgemäß und unter Bedingungen, die vom Hersteller als Fehlanwendung vernünftigerweise vorhersehbar sind, verwendet werden (siehe Anhang D). Dieses Dokument legt die geeigneten technischen Maßnahmen zur Beseitigung oder Verminderung der Risiken fest, die von den signifikanten Gefährdungen während des Transports, der Bestückung, der Demontage, des Außerbetriebsetzens, der Verschrottung, des Betriebs und der Instandhaltung des Fahrmischers ausgehen.
1.3 Dieses Dokument gilt nicht für Maschinen, die vor dem Datum der Veröffentlichung dieses Dokuments durch CEN hergestellt worden sind.
Bétonnières portées - Prescriptions de sécurité
1.1 Le présent document spécifie les prescriptions de sécurité pour les bétonnières portées.
Le présent document couvre également les interfaces avec le camion ou la remorque sur le côté de l’unité de malaxage (mais pas le camion ou la remorque même).
NOTE 1 Camions ou remorques de catégorie N3 ou O4 construits spécifiquement pour le transport de marchandises et classés conformément à la Directive 2007/46/CE.
Le présent document ne couvre pas:
a) l’équipement additionnel (convoyeur à courroie, pompe à mortier, pompe à béton, flèche de coulage du béton);
b) les prescriptions pour l’utilisation dans les tunnels;
c) les bétonnières portées ou automotrices équipées de systèmes à chargement automatique;
d) les malaxeurs à déchargement par l’avant;
e) les unités de malaxage avec commande articulée;
f) systèmes de nettoyage du tambour des bétonnières portées;
g) source(s) d'énergie.
Le présent document n’aborde pas les véhicules porteurs, par exemple les camions, les tracteurs, les engins de construction et l’équipement mobile de manutention industrielle ou autres véhicules non automoteurs.
Le présent document ne contient aucune prescription couverte par les directives relatives à la construction des véhicules ou par les codes de la route nationaux.
NOTE 2 L’utilisation sur routes publiques est régie par des réglementations nationales.
1.2 Le présent document traite de tous les phénomènes dangereux, situations dangereuses et événements dangereux significatifs applicables aux bétonnières portées lorsqu’elles sont utilisées normalement et lorsqu’elles sont utilisées dans des conditions de mauvais usage raisonnablement prévisible par le constructeur (voir Annexe D). Le présent document spécifie les mesures techniques appropriées pour éliminer ou réduire les risques émanant des phénomènes dangereux significatifs pendant le transport, l’assemblage, le désassemblage, la désactivation, la mise au rebut, le fonctionnement et la maintenance de la bétonnière portée.
1.3 Le présent document ne s’applique pas aux machines qui sont fabriquées avant sa date de publication par le CEN.
