This European Standard specifies the general safety requirements for tractor-dozers, described in EN ISO 6165:2012. 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 requirements formulated in prEN 474-1:2017. This part does not repeat the requirements from prEN 474-1:2017, but adds or replace the requirements for application for tractor-dozers. This European Standard deals with all significant hazards, hazardous situations and events relevant to earth-moving machinery, when used as intended and under conditions foreseen but also taking into account any reasonably foreseeable misuse thereof (see Clause 4). This European Standard specifies the appropriate technical measures to reduce risks arising from the significant hazards, hazardous situations and events during the whole foreseeable lifecycle of the machinery. This European Standard is not applicable to earth-moving machinery, which are manufactured before the date of publication of this European Standard by CEN. NOTE For travelling on public roads, national traffic regulations apply (e.g. braking, steering, lighting, towing etc.) until harmonized requirements are available.
