Earth-moving machinery - Safety - Part 12: Requirements for cable excavators

This part of EN 474 deals with all significant hazards, hazardous situations and events relevant to cable excavators as defined in EN ISO 6165:2006, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).
This European Standard applies also to cable excavators, their undercarriage and upper-structure, if intended for use in combination with other equipment or attachment, such as drill rigs, pile driving and extracting equipment and moving equipment (e.g. rail track, walking legs, pontoon, ship) or stationary undercarriage. This European Standard is not dealing with the specific hazards due to these additional equipment or attachment.
NOTE   For these additional equipment or attachment, relevant specific European Standards should be considered where available, for example:
-   for pile driving and extracting equipment: EN 996:1995;
-   for drill rigs: EN 791:1995.
The requirements of this part are complementarily to the common requirements formulated in EN 474-1:2006.
This part does not repeat the requirements from EN 474-1:2006, but adds or replaces the requirements for application for cable excavators.
This part specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards, hazardous situations and events during commissioning, operation and maintenance of the machinery in the scope.
This European Standard is not applicable to cable excavators manufactured before the date of publication of this European Standard by CEN.

Dieses Dokument behandelt nicht die speziellen Gefährdungen, die sich aus diesen zusätzlichen Ausrüstungen und Einrichtungen ergeben.
ANMERKUNG   Für diese zusätzlichen Ausrüstungen und Einrichtungen sollten (soweit vorhanden) die speziellen Europäischen Normen beachtet werden, wie z. B.
-   für Ramm- und Ziehgeräte: EN 996:1995;
-   für Bohrgeräte: EN 791:1995.
Die Anforderungen gelten ergänzend zu den allgemeinen Anforderungen des Teil 1.
Dieser Teil wiederholt nicht die Anforderungen des Teils 1, sondern ergänzt oder ersetzt diese für den Einsatz von Seilbaggern.
Dieser Teil beschreibt die geeigneten technischen Maßnahmen, um die Risiken zu mindern oder zu beseitigen, die aufgrund signifikanter Gefährdungen, Gefährdungssituationen und Gefährdungsereignisse, die während der Inbetriebnahme, dem Betrieb, der Instandhaltung von Seilbaggern eintreten können.
Diese Europäische Norm ist nicht anzuwenden für Seilbagger, die vor der dieser Europäischen Norm durch CEN hergestellt wurden

La présente partie du prEN 474 traite de tous les phénomenes, situations et événements dangereux significatifs relatifs aux pelles a câbles définies dans l'EN ISO 6165:2002, lorsqu'elles sont utilisées comme prévu ou dans des conditions de mauvais usage que le fabricant peut raisonnablement prévoir (voir Article 4).
La présente Norme européenne s’applique également aux pelles a câbles, a leur structure porteuse et a leur structure supérieure, lorsqu’elles sont destinées a etre utilisées en association avec d’autres équipements ou accessoires, tels que équipements de forage, matériels de battage et d’arrachage avec des équipements mobiles (par exemple, sur rails, sur patins, sur ponton, sur barge) ou des structures porteuses fixes. La présente Norme européenne ne traite pas des phénomenes dangereux spécifiques engendrés par ces équipements ou accessoires supplémentaires.
NOTE   Pour ces équipements ou accessoires supplémentaires, il convient de prendre en considération les Normes européennes spécifiques correspondantes, lorsqu’elles sont disponibles, par exemple :
-   pour le matériel de battage et d’extraction de pieux : EN 996:1995 ;
-   pour les appareils de forage : EN 791:1995.
Les prescriptions figurant dans la présente partie viennent en complément des prescriptions communes présentées dans la partie 1.
La présente partie ne répete pas les prescriptions de la partie 1 mais en ajoute ou en remplace certaines applicables aux pelles a câbles.

The requirements of this part are complementarily to the common requirements formulated in EN 474-1:2006.
This part does not repeat the requirements from EN 474-1:2006, but adds or replaces the requirements for
application for cable excavators.
This part specifies the appropriate technical measures to eliminate or reduce risks arising from the significant
hazards, hazardous situations and events during commissioning, operation and maintenance of the machinery in
the scope.
This European Standard is not applicable to cable excavators manufactured before the date of publication of this
European Standard by CEN.
