BS ISO 12117-2:2008+A1:2016建立了一种一致且可重复的方法，用于评估静态载荷下挖掘机滚动过度保护结构（ROPS）的承载特性，并规定了此类载荷下代表性试样的性能要求。它适用于ISO 6165中定义的液压挖掘机的ROPS，质量大于6 t且小于50 t。当机器绕其旋转框架的纵轴旋转360°时，ROPS将确保座椅安全带操作员的最小挤压保护空间，而不会与小于30°的硬粘土斜坡失去接触。 ROPS适用于存在翻滚风险的地方。它还适用于用于物体或材料搬运、拆卸或带有磁铁、抓斗、抓斗或多爪抓斗等附件的基于挖掘机的定购挖掘机的ROPS。它不适用于带提升驾驶室立管的挖掘机。注:由于用于推导验收标准的实验和统计数据集的限制，ISO1217的本部分旨在适用于总工作质量不超过50000kg的挖掘机。这并不排除将ISO1217本部分所述程序应用于具有较大或较小质量的挖掘机的可能性，但不包括专门为采矿应用设计的挖掘机，这些要求可能导致设计不切实际。 交叉引用:ISO 3164ISO 5353ISO 6165ISO 9248ISO 148-1ISO 898-1ISO 898-2ISO 3449ISO 3471ISO 6016ISO 6683:2005ISO 10262:1998ISO 12117-1EN 13510购买本文件时提供的所有现行修订版均包含在购买本文件中。

BS ISO 12117-2:2008+A1:2016 establishes a consistent and reproducible means of evaluating the load-carrying characteristics of roll-overprotective structures (ROPS) for excavators under static loading, and prescribes performance requirements of a representative specimen under such loading.It applies to ROPS of hydraulic excavators as defined in ISO 6165 with a mass of over 6 t and less than 50 t. ROPS will ensure minimum crush protection space for a seat-belted operator when the machine rolls 360° about longitudinal axis of its revolving frames without losing contact with a hard clay slope of less than 30°. ROPS is to be applied where the risk of roll-over exists.It also applies to ROPS for excavator-based orderivated excavators used in object or material handling, demolition or with attachments such as magnets, clamshell, grab or multi-clawgrab.It does not apply to excavators with elevating cab risers.NOTE This part of ISO12117 is intended to be applied to excavators having a gross operating mass up to 50000kg due to the limitation of the experimental and statistical data set used to derive acceptance criteria. This does not preclude the possibility of applying the procedure described in this part of ISO12117 to excavators having larger or smaller masses, with the exclusion of excavators specially designed for mining application, where the requirements may lead to impractical design.Cross References:ISO 3164ISO 5353ISO 6165ISO 9248ISO 148-1ISO 898-1ISO 898-2ISO 3449ISO 3471ISO 6016ISO 6683:2005ISO 10262:1998ISO 12117-1EN 13510All current amendments available at time of purchase are included with the purchase of this document.
