ActiveEarth-moving machinery—Laboratory evaluations of protective structures—Specifications for deflection-limiting volume
土方机械 保护结构的实验室鉴定 挠曲极限量的规定
Application Summary AI generated
This standard specifies the deflection-limiting volume (DLV) for laboratory evaluations of Roll-Over Protective Structures (ROPS) and Falling-Object Protective Structures (FOPS) on earth-moving machinery. It is applied during the design and certification testing of cabs and frames on equipment such as bulldozers, excavators, and loaders to ensure operator survival space is maintained under impact loads. The standard is used by manufacturers and testing laboratories in the construction and mining industries to validate structural compliance with international safety requirements.
