4、 pages02.10 DIN EN 474-3:2010-02 2 Start of validity This standard takes effect on 01 February 2010. National foreword This standard includes safety requirements. This standard has been prepared by Technical Committee CEN/TC 151 “Construction equipment and building material machines Safety” (Secreta
5、riat: 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-/Straenbau-maschinen of Section Bau- und Baustoffmaschinen. Representatives of manufacturers and us
6、ers 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, (valid until 28 December 2009) and the “rev
7、ised 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 essential requirements of the directives. On
8、ce 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”). The European Standards referred to in cl
9、ause 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. Amendments This standard differs from DIN EN 474-3:2007-07 as
10、 follows: a) The Foreword has been revised. b) Normative references have been updated. c) Technical requirements regarding falling-object protective structures (5.5.2) have been updated. d) Inclusion of Annex ZB “Relationship between this European Standard and the Essential Requirements of EU Direct

DIN EN 474-3:2010-02 EN 474-3:2006+A1:2009 (E) 6 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 c
30、overed 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 provisions of the other standards, for machines that have been desi
31、gned and built according to the provisions of this type C standard. DIN EN 474-3:2010-02 EN 474-3:2006+A1:2009 (E) 7 1 Scope This part of EN 474 deals with all significant hazards, hazardous situations and events relevant to loaders as defined in EN ISO 6165:2006, when they are used as intended and
32、under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This part also deals with fork application, single heavy object handling application, object handling application and log handling. The requirements of this part are complementary to the common requiremen
33、ts formulated in !EN 474-1:2006+A1:2009“. This part does not repeat the requirements from !EN 474-1:2006+A1:2009“, but adds or replaces the requirements for application for loaders. This part specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazar
34、ds, hazardous situations and events during commissioning, operation and maintenance of loaders. This European Standard is not applicable to loaders manufactured before the date of publication of this European Standard by CEN. 2 Normative references The following referenced documents are indispensabl
35、e for the application of this European Standard. For dated references, only the edition cited applies.

NOTE Definitions used in EN and ISO standards referred to in this European Standard are also valid for this
42、 document. 3.1 loader self-propelled crawler or wheeled machine, having a front-mounted equipment primarily designed for loading operation (bucket use), which loads or excavates through forward motion of the machine NOTE 1 A loader work cycle normally comprises filling, elevating, transporting and d
43、ischarging material. NOTE 2 Derivative machinery; loaders can also be used for derivative application (see !EN 474-1:2006+A1:2009“, 3.1.2). 3.2 compact loader loader with an operating mass (see !ISO 6016:2008“) of 4 500 kg or less, designed to work in confined spaces with the associated needs for gr
44、eater manoeuvrability 3.3 skid steer loader loader normally having an operators station between attachment-supporting structures and steered by using variation of speed and/or direction of rotation between traction drives on opposite sides of a machine with fixed axles 3.4 swing loader loader having
45、 a swing type lift arm with a swinging angle to the left and right from a straight position NOTE A swing loader work cycle is normally similar to a loader cycle but additionally work can be done offset of the machine track. 4 List of additional significant hazards See Annex A. NOTE Annex A (normativ
46、e) contains all the significant hazards, hazardous situations and events, as far as they are dealt with in this European Standard, identified by risk assessment as significant for this type of machinery and which require action to eliminate or reduce the risk. 5 Safety requirements and/or measures 5
