农业机械安全第13部分：大型旋转割草机

[中文适用范围]： 本文件与 ISO 4254-1 一起使用时，规定了带有单个或多个切削元件的牵引式、半悬挂式或安装式大型旋耕机的设计和构造的安全要求及其验证，这些割草机的切削元件尖端圆为1000 毫米或更大，适用于安装在推进式拖拉机或机器上的任何单个切割元件组件，适用于农业割草设备，设计用于通过冲击切碎作物残茬、草和小刷子。 它描述了消除或减少由于一个人（操作员）在正常操作和维修过程中预期用途和合理可预见的误用这些机器而产生的危险的方法。 此外，它还规定了制造商要提供的安全工作实践信息的类型。 注 1：当在农业以外使用时，本文件中未规定的附加要求也适用。 本文件不适用于： ——设计用于 ISO 4254-12 所涵盖的饲料作物收割的转盘割草机、转鼓割草机和连枷割草机； ——臂式大型旋转割草机； ——步行控制机动割草机； ——ISO 5395 系列涵盖的割草机。 当本文件的要求与 ISO 4254-1 中规定的要求不同时，对于根据本文件规定设计和制造的机器，本文件的要求优先于 ISO 4254-1 的规定。 本文件也不适用于环境危害、道路安全、电磁兼容性、振动以及与动力传输运动部件相关的危害。 它也不适用于与由专业服务人员进行的维护或修理相关的危险。 本文件与 ISO 4254-1 一起处理与按预期使用并在制造商预见的条件下使用的大型旋转割草机相关的所有重大危险、危险情况和事件。 （附录 A 中提供了重大危险列表。 ） 注 2：本文件中涉及的两台割草机（刚性甲板大型旋转割草机和林道式多节可折叠翼大型旋转割草机）的示例图解为见附录 C、C.1。 注 3：本文件中未涉及的割草机示例图见附件 C、C.2。 注4：ISO 14982规定了评估各种移动式农业机械电磁兼容性的测试方法和验收标准。 本文件不适用于发布日期之前制造的大型旋转割草机。 1 [外文原描述]： This document, when used together with ISO 4254 - 1 , specifies the safety requirements and their verification for the design and construction of towed, semi-mounted, or mounted large rotary mowers with single or multiple cutting elements which have a cutting element tip circle of 1 000 mm or greater for any single cutting - element assembly, mounted on a propelling tractor or machine, intended for agricultural mowing equipment and designed for shredding crop residue, grass and small brush by impact. It describes methods for the elimination or reduction of hazards arising from the intended use and reasonably foreseeable misuse of these machines by one person (the operator) in the course of normal operation and service. In addition, it specifies the type of information on safe working practices to be provided by the manufacturer. NOTE 1 When used outside of agriculture, additional requirements not specified in this document can be applicable. This document is not applicable to: — rotary disc mowers, rotary drum mowers, and flail mowers designed for forage crop harvesting as covered by ISO 4254 - 12 ; — arm-type large rotary mowers; — pedestrian-controlled motor mowers; — lawn mowers covered by the ISO 5395 series . When requirements of this document are different from those which are stated in ISO 4254 - 1 , the requirements of this document take precedence over the provisions of ISO 4254 - 1 for machines that have been designed and built according to the provisions of this document. This document is also not applicable to environmental hazards, road safety, electromagnetic compatibility, vibration and hazards related to moving parts for power transmission. It is also not applicable to hazards related to maintenance or repairs to be carried out by professional service personnel. This document, taken together with ISO 4254 - 1 , deals with all the significant hazards, hazardous situations and events relevant to large rotary mowers used as intended and under the conditions foreseen by the manufacturer. (A list of significant hazards is provided in Annex A .) NOTE 2 Example illustrations of two mowers (a rigid-deck large rotary mower and a trail-type multi-section, foldable-wing large rotary mower) dealt with in this document are shown in Annex C , C.1 . NOTE 3 Example illustrations of mowers not dealt with in this document are shown in Annex C , C.2 . NOTE 4 ISO 14982 specifies test methods and acceptance criteria for evaluating the electromagnetic compatibility of all kinds of mobile agricultural machinery. This document is not applicable to large rotary mowers which are manufactured before the date of publication.
