Abstract: When the new energy mucking equipment is applied in construction of highaltitude transportation projects, many problems encounter, such as poor endurance, high purchase cost, and incomplete supporting equipment, facilities and security. Therefore, the application status of electric mucking equipment is introduced, and an effective technical route that can address the problems mentioned above, vehicle electricity separation mode based on battery swapping technology, is proposed to cope with the application scenario requirements and technology development trends. The implementation of this technical route should be based on the development of power exchange equipment, the standardization of power battery system, the development of rapid battery swapping equipment, and the construction of energy security infrastructure. It is also necessary to conducted research and development of miniaturized mobile charging equipment and cable power supply technology. At the same time, various business models such as equipment leasing and labor subcontracting should be actively explored to accelerate the engineering application of electric mucking equipment.
