5、ble German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Working Committee NA 060-13-01 AA Erdbau-/Straenbau-maschinen of Section Bau- und Baustoffmaschinen. Representatives of manufacturers and users of earth-moving machinery, an

6、d 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, (valid until 28 December 2009) and the “revised Machinery Directive”, Direct

7、ive 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 essential requirements of the directives. Once this standard is cited in the

8、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”). The European Standards referred to in clause 2 and in the bibliography of

9、 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. Amendments This standard differs from DIN EN 474-2:2007-07 as follows: a) The Foreword has bee

10、n revised. b) Inclusion of Annex ZB “Relationship between this European Standard and the Essential Requirements of EU Directive 2006/42/EC”.

28、 the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this European Standard. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the

29、provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. DIN EN 474-2:2010-02 EN 474-2:2006+A1:2008 (E) 6 1 Scope This part of EN 474 deals with all significant hazards, hazardous situations and events relevant to wheel an

30、d crawler tractor-dozers 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 part also deals with rear-mounted winches for use on tractor-dozers. The requirements of this part are comp

31、lementary 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 tractor-dozers. This part specifies the appropriate technical measures to eliminate or reduce risks arising from

32、the significant hazards, hazardous situations and events during commissioning, operation and maintenance of tractor-dozers. This European Standard is not applicable to tractor-dozers manufactured before the date of publication of this European Standard by CEN. 2 Normative references The following re
