GB/T 37899-2019 in English

Interpretation of GB/T 37899—2019 National Standard of the People's Republic of China

Background of Standard Formulation and Analysis of Technological Evolution

With the rapid development of the earth-moving machinery industry, ultra-large hydraulic excavators are increasingly used in mining, construction and other fields. In order to ensure the safety, reliability and environmental protection of the equipment, GB/T 37899—2019 came into being. This standard replaces the old version of the standard and comprehensively regulates the classification, requirements, test methods and inspection rules of ultra-large hydraulic excavators in combination with international advanced technologies.
