1.1本欧洲标准与EN ISO 4254 1和EN 15811一起使用时，规定了3.1中定义的用于果园操作（WPO）的所有类型和尺寸的自行式粗糙地形工作平台的安全要求和措施，用于农业，旨在在未改良的自然地形和/或扰乱的地形上工作，并打算将至少两名人员搬到果园进行水果采摘，稀疏，修剪或与果园有关的其他操作的工作岗位TM的工作平台保持平静，意图是人员只能在地面或底盘的入口处进入工作平台。 它描述了消除或减少在正常运行和维修过程中由至少两个人（操作员）预期使用这些机器所引起的危险的方法，但与传送带和叉子有关的危险除外。此外，还规定了制造商提供的关于安全工作实践（包括剩余风险）的信息类型。 当本文件的要求与EN ISO 4254 1中规定的要求不同时，本文件的要求优先于EN ISO 4254 1对于设计和制造的机器的要求

1.1 This European Standard, when used together with EN ISO 4254 1 and EN 15811, specifies safety requirements and measures for self-propelled rough-terrain work platforms for orchard’s operations (WPO) operating at a maximum of 3 m high as defined in 3.1, where the vertical projection of the centre of the area of the platform in all platform configurations at the maximum chassis inclination specified by the manufacturer is always inside the tipping lines, used in agriculture, designed to work on unimproved natural terrain and/or disturbed terrain and intended to move at least two persons to working positions in an orchard where they are carrying out fruit picking, thinning out, pruning, or other operations related to orchard from the work platform. NOTE For examples of rough-terrain work platforms for orchard’s operations (WPO), see Figures E. 1 to E.3. This European Standard describes methods for the elimination or reduction of hazards arising from the intended use of these machines in the course of normal operation and service, except hazards related to conveyor belts and elevators for the bin. In addition, it specifies the type of information on safe working practices (including residual risks) to be provided by the manufacturer. When requirements of this document are different from those which are stated in EN ISO 4254 1, the requirements of this document take precedence over the requirements of EN ISO 4254 1 for machines that have been designed and built according to the provisions of this document. This European Standard, taken together with EN ISO 4254 1 and EN 15811, deals with all the significant hazards, hazardous situations and events (as listed in Table 1) relevant to WPOs, when they are used as intended and under the conditions of misuse foreseeable by the manufacturer. It does not cover the hazards arising from: a) use in potentially explosive atmospheres; b) getting on and off the work platform at changing levels; c) environmental aspects; d) road safety. 1.2 This European Standard does not apply to: a) Mobile Elevating Work Platforms (MEWPs) (see EN 280); NOTE 1 Figure E.4 gives an example of this type of machine. b) boom-type MEWPs (see EN 280); NOTE 2 Figure E.5 and E.6 give examples of this type of machine. c) tail lifts (see EN 1756-1 and EN 1756-2); d) mast climbing work platforms (see EN 1495); e) lifting tables (see EN 1570-1); f) aircraft ground support equipment (see e.g. EN 1915-1 and EN 1915-2); g) elevating operator positions on industrial trucks (see EN 1726-2); h) unguided work cages suspended from lifting appliances (see e.g. EN 1808); i) machines having centre of the area of the platform outside the tipping lines. NOTE 3 Figure E.7 gives an example of this type of machine.
