BS EN 474-12:2006+A1:2008EN 474-12:2006+A1:2008 (E) 5 Introduction This part of EN 474 is a type C standard as stated in EN ISO 12100-1:2003.

31、The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indi-cated in the scope of this European Standard. When provisions of this type C standard are different from those stated in type A or B standards, the provisions of this type C standard take pr

32、ecedence over the provisions of the other standards, for machines that have been de-signed and built according to the provisions of this type C standard. BS EN 474-12:2006+A1:2008EN 474-12:2006+A1:2008 (E) 6 1 Scope This part of EN 474 deals with all significant hazards, hazardous situations and eve

33、nts 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 int

34、ended 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 add

35、itional 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 complemen

36、tarily 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 t

37、he 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. 2 Normative references The
