标准摘要
[中文适用范围]： 本部分ISO 12117建立了一种一致且可重复的方法，用于评估挖掘机在静态载荷下的防滚翻保护结构（ROPS）的承载特性，并规定了代表性样品在此类载荷下的性能要求。它适用于ISO 6165定义的、质量超过6吨且小于50吨的液压挖掘机的ROPS。ROPS将确保当机器绕其回转框架的纵轴翻滚360°且不脱离坡度小于30°的硬粘土坡时，为系好安全带的操作员提供最小挤压保护空间。ROPS适用于存在翻滚风险的地方。它还适用于用于物体或物料搬运、拆除或带有磁铁、抓斗、抓斗或多爪抓斗等附件的挖掘机或衍生挖掘机的ROPS。它不适用于带有升降驾驶室升高架的挖掘机。注：本部分ISO 12117旨在适用于总操作质量高达50,000公斤的挖掘机，这是由于用于推导验收标准的实验和统计数据集的限制。这并不排除将本部分ISO 12117中描述的程序应用于质量更大或更小的挖掘机，但不适用于专门设计用于采矿应用的挖掘机，因为那里的要求可能导致不切实际的设计。 [外文原描述]： ISO 12117-2:2008 establishes a consistent and reproducible means of evaluating the load-carrying characteristics of roll-over protective structures (ROPS) for excavators under static loading, and prescribes performance requirements of a representative specimen under such loading. ROPS are to be used where the risk of roll-over exists. ISO 12117-2:2008 applies to ROPS of hydraulic excavators as defined in ISO 6165 with a mass of over 6 t and less than 50 t. It also applies to ROPS for excavator-based or derivated excavators used in object or material handling, demolition or with attachments such as in log-handling and forestry applications. It does not apply to excavators with elevating cab risers.
