This part of EN 474 specifies the general safety requirements for earth-moving machinery described in EN ISO 6165:2006, except rollers and horizontal directional drill. NOTE 1 Rollers are covered by EN 500. NOTE 2 Horizontal directional drills are covered by EN 791. This part also applies to derivative machinery (see 3.1.2) designed primarily for use with equipment to loosen, pick-up, move, transport, distribute and grade earth and rock. This part gives the common safety requirements for earth-moving machinery families and is intended to be used in conjunction with one of the EN 474 parts 2 to 12. These machine specific parts (EN 474-2 to -12) do not repeat the requirements from EN 474-1:2006+A1:2009, but add or replace the requirements for the family in question. NOTE 3 The requirements specified in this part of the standard are common to two or more families of earth- moving machinery. Specific requirements in EN 474 parts 2 to 12 take precedence over the respective requirements of EN 474-1:2006+A1:2009. For multipurpose machinery the parts of the standard that cover the specific functions and applications have to be used e.g. a compact loader also used as a trencher shall use the relevant requirements of EN 474 parts 1, 3 and 10. The standard also covers general requirements for attachments intended to be used with earth moving machine families covered in the scope.Except for part 12 this European Standard does not deal with the electrical hazards related to the main circuits and drives of machinery when the principal source of energy is electrical. This European Standard does not deal with towing of trailers.
