In the field of construction machinery in China, significant breakthroughs have been made in recent years, especially in the research and development of large excavators. The bucket loading capacity of some models far exceeds that of traditional small and medium-sized equipment. The typical bucket capacity of traditional excavators (such as 20-ton models) is about 0.7-0.8 cubic meters, and the total capacity of three units is about 2.1-2.4 cubic meters. In contrast, the following domestic excavators, with their super-large bucket design, not only easily exceed this standard in single excavation volume, but also set a new efficiency record:
