This Standard establishes a consistent and reproducible means of evaluating the load-carrying characteristics of tip-over protective structures (TOPS) under static loading, and prescribes performance requirements of a representative specimen under such loading.
This Standard applies to TOPS of compact excavators (as defined in GB/T 8498) with swing type boom, having an operating mass of 1 000 kg to 6 000 kg.
