This standard has been prepared by Technical Committee CEN/TC 151 “Construction equipment and building material machines Safety” (Secretariat: DI
5、N, 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 Baustoffmaschinen. Representatives of manufacturers and users of e
6、arth-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 2006/42/EC, which apply to machines that are either first pla
7、ced on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of that directive. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applyin
8、g this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The European Standards referred to in this standard have been published as the corresponding DIN EN or DIN EN ISO Standards with the same number. For the International Standards refe
9、rred to in this standard there are no national standards available unless they have been published as DIN ISO standards with the same number. Amendments This standard differs from DIN EN 474-4:2010-02 as follows: a) the Foreword has been revised; b) Subclause 5.5.3.3.4 b) has been amended; c) Annex

29、+A2:2012 (E) 4 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 indicated in the scope of this European Standard. When provisions of this type C standard ar
30、e 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 designed and built according to the provisions of this type C standard.

31、A2:2012 (E) 5 1 Scope This part of EN 474 deals with all significant hazards, hazardous situations and events relevant to wheel and crawler backhoe loaders as defined in EN ISO 6165:2006, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufactur
32、er (see Clause 4). This part also deals with fork application, object handling application and log handling. The requirements of this part are complementary to the common requirements formulated in !EN 474-1:2006+A1:2009“. This does not repeat the requirements from !EN 474-1:2006+A1:2009“, but adds
33、or replaces the requirements for application for backhoe loaders. 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 backhoe loaders. This Europea
34、n Standard is not applicable to machinery 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. For dated references, only the edition cited applies. For

41、ons For the purposes of this European Standard, the terms and definitions given in !EN 474-1:2006+A1:2009“, EN ISO 12100-1:2003 and the following apply. NOTE 1 Terminology for backhoe loaders is specified in ISO 8812:1999 and most common backhoe loaders are illustrated in Annex C of this European St
42、andard. NOTE 2 Definitions used in EN and ISO standards referred to in this European Standard are also valid for this document. 3.1 backhoe loader self-propelled crawler or wheeled machine having a main frame designed to carry both front-mounted equipment and rear-mounted backhoe equipment, normally
43、 with stabilisers or outriggers (see EN ISO 6165:2006) NOTE 1 When used in backhoe mode, the machine is stationary and normally digs below ground level, but when used in loader mode (bucket use), the machine loads through forward motion. NOTE 2 A backhoe work cycle normally comprises excavating, ele
44、vating, swinging and discharging material. A loader work cycle normally comprises filling, elevating, transporting and discharging material. 3.2 compact backhoe loader backhoe loader with an operating mass (see !ISO 6016:2008“) of 4 500 kg or less, designed to work in confined spaces with the associ
45、ated needs for greater manoeuvrability 4 List of additional significant hazards See Annex A. NOTE Annex A (normative) 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
46、type of machinery and which require action to eliminate or reduce the risk. 5 Safety requirements and/or measures 5.1 General Backhoe loaders shall comply with the requirements of !EN 474-1:2006+A1:2009“, as far as not modified or replaced by the requirements of this part. 5.2 Protection 5.2.1 Roll-
47、over protective structures (ROPS) !EN 474-1:2006+A1:2009“, 5.3.3 applies with the following addition for compact backhoe loaders: DIN EN 474-4:2012-05 EN 474-4:2006+A2:2012 (E) 7 The portion of deflection-limiting volume (DLV) above the LA (SIP) line according to !EN ISO 3164:2008“ is allowed to dev
