This standard specifies the minimum performance requirements and test methods for tire-type machine service brake systems, auxiliary brake systems, parking brake systems and speed governors to enable the control of earth-moving machinery operating on construction sites or traveling on roads. Unified evaluation of dynamic performance. This standard applies to self-propelled tire loaders, bulldozers, graders, backhoe loaders, scrapers, excavators and dump trucks as defined in GB/T 8498.
