AbolishedEarth-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 defines the spatial volume that must remain unobstructed during structural deflection to protect the operator in a rollover or falling-object incident. The standard is applied in testing and certification contexts for construction and mining equipment such as bulldozers, loaders, and excavators.
