标准摘要
[中文适用范围]： 本文件给出了 ISO 20474-1 定义的轮式推土机和履带式推土机的特定安全要求，该要求规定了两个或多个土方机械系列通用的一般安全要求。 本文件中给出的具体要求优先于 ISO 20474-1 的一般要求。 本文件涉及与按预期使用或在制造商合理预见的误用条件下使用其范围内的土方机械（参见 ISO 20474-1:2017，附录 A）相关的所有重大危险、危险情况和事件。 它规定了消除或减少调试、运行和维护过程中相关危险、危险情况或事件所产生的风险的适当技术措施。 本文件不适用于其发布之日之前制造的机器。 [外文原描述]： ISO 20474-2:2017 gives the safety requirements specific to wheeled dozers and crawler dozers as defined in ISO 6165 as well as for the rear-mounted winches on dozers. It is intended to be used in conjunction with ISO 20474‑1, which specifies general safety requirements common to two or more earth-moving machine families. The specific requirements given in this document take precedence over the general requirements of ISO 20474‑1. ISO 20474-2:2017 deals with all significant hazards, hazardous situations and events relevant to the earth-moving machinery within its scope (see ISO 20474‑1:2017, Annex A) when used as intended or under conditions of misuse reasonably foreseeable by the manufacturer. It specifies the appropriate technical measures for eliminating or reducing risks arising from relevant hazards, hazardous situations or events during commissioning, operation and maintenance. ISO 20474-2:2017 is not applicable to machines manufactured before the date of its publication.
