EN 474-3:2006+A1:2009 (E) 6 Introduction This part of EN 474 is a type C standard as stated in EN ISO 1210
24、0-1:2003. 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 are different from those which are stated in type A or B standards, the provisions of this type
25、 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. EN 474-3:2006+A1:2009 (E) 7 1 Scope This part of EN 474 deals with all significant hazards, hazardous situations and events rele
26、vant to 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 manufacturer (see Clause 4). This part also deals with fork application, single heavy object handling application, object handling application and log
27、 handling. The requirements of this part are complementary to the common requirements 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
28、 technical measures to eliminate or reduce risks arising from the significant hazards, 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

36、 referred to in this European Standard are also valid for this 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 c
37、ycle normally comprises filling, elevating, transporting and discharging 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, design
38、ed to work in confined spaces with the associated needs for greater 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 side
39、s of a machine with fixed axles 3.4 swing loader loader having 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 addi
40、tional 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 type of machinery and which require action to elimina
