Earth-moving machinery. Laboratory tests and performance requirements for protective structures of excavators - Roll-over protective structures (ROPS) for excavators of over 6 t1 Scope This part of ISO 12117 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. 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
