This document specifies the general safety requirements for earth-moving machinery, hereinafter also referred to as machines, described in EN ISO 6165:2012, except horizontal directional drills. NOTE 1 Horizontal directional drills are covered by EN 16228 1 and EN 16228 3. This document gives the common safety requirements for earth-moving machinery families (see EN ISO 6165:2012, 3.4) and is intended to be used in conjunction with relevant parts of EN 474-2 to EN 474-13. These machine specific parts (EN 474 2 to EN 474−13) do not repeat the requirements from EN 474 1:2022 but supplement or modify the requirements for the family in question. NOTE 2 The requirements specified in this part of the standard are common to two or more families of earth- moving machinery. This document does not provide requirements for main electrical circuits and drives of machinery when the primary source of energy is an external electrical supply. This document does not provide performance requirements for safety related functions of control system(s). This document does not deal with towing of trailers. This document does not deal with demolition machinery. This document deals with 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 Annex A). The following significant and relevant hazards are not covered in this document: — Laser; — Lightning. This document 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 as described in EN ISO 12100:2010, 5.4. This document is not applicable to earth-moving machinery which are manufactured before the date of publication of this document by CEN. NOTE 3 For travelling on public roads, national traffic regulations apply (e.g. braking, steering, lighting, towing, etc.) until harmonized requirements are available.
