National foreword This standard includes safety requirements. This standard has been prepared by Technical Committee CEN/TC 151 “Construction equipmen
5、t building material machines Safety” (Secretariat: DIN, Germany). The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Working Committee NA 060-13-01 AA Erdbau-/Straenbaumaschinen of Section Bau- und Baustoffmaschi
6、nen. Representatives of manufacturers and users of earth-moving machinery, and of the employers liability insurance associations contributed to this standard. This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directive 98/37/EC,
7、 (valid until 28 December 2009) and the “revised Machinery Directive”, Directive 2006/42/EC, which takes effect on 29 December 2009, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the
8、essential requirements of the directives. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity
9、”). The European Standards referred to in clause 2 and in the bibliography of the EN have been published as the corresponding DIN EN or DIN EN ISO Standards with the same number. For the International Standards referred to in this standard there are no national standards available, except for that b

36、 and United Kingdom. DIN EN 474-12:2010-05 EN 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. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indi-cated in the scope of this Eur
37、opean 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 precedence over the provisions of the other standards, for machines that have been de-signed and built according to the provisions of this typ
38、e C standard. DIN EN 474-12:2010-05 EN 474-12:2006+A1:2008 (E) 6 1 Scope 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 reason
39、ably 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
40、 (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 w
41、here 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 repla
42、ces 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 Eur
43、opean Standard is not applicable to cable excavators manufactured before the date of publication of this European Standard by CEN. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.
