This standard specifies additional requirements and/or exceptions from EN 474-1:1994 'Earth-moving machinery - Safety - Part 1: General requirements'. This standard applies to wheel and crawler excavators defined in ISO/DIS 6165:1994, and gives additional requirements for attachments and for derivated machinery. This standard applies for compact excavators as defined in 3.2.1 and figure C.2 and walking excavators as defined in 3.2.2 and figure C.5. This standard deals with the significant hazards pertinent to hydraulic excavators when they are used as intended and under the conditions foreseen by the manufacturer (see Annex A of this standard and Annex C of EN 474-1:1994). Bucket wheel excavators are not covered in this standard.
