This part of EN 474 deals with all significant hazards, hazardous situations and events relevant to pipelayers 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). 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 pipelayers. 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 pipelayers. This part specifies additional requirements for rear mounted winches. Pipelayers with rotating upper structure are excluded from the scope of this document. However, specific requirements are under development. This European Standard is not applicable to pipelayers manufactured before the date of publication of this European Standard by CEN.
