BS ISO 12117-2:2008+A1:2016
This standard BS ISO 12117-2:2008+A1:2016 Earth-moving machinery. Laboratory tests and performance requirements for protective structures of excavators is classified in these ICS categories:
- 53.100 Earth-moving machinery
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 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 or derivated excavators used in object or material handling, demolition or with attachments such as magnets, clamshell, grab or multi-claw grab.
It does not apply to excavators with elevating cab risers.
This part of ISO 12117 is intended to be applied to excavators having a gross operating mass up to 50 000 kg 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 ISO 12117 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.
