[0002] Subway construction tractors are primarily used during subway construction, performing traction tasks in construction environments such as subway tunnels. They are primarily responsible for transporting materials and equipment and towing construction vehicles within complex, underdeveloped construction sites.

[0003] Currently, the vast majority of subway traction vehicles are powered by internal combustion engines or electric power. Internal combustion engines are expensive to operate and maintain, and they contribute significantly to air pollution. Electric motors are now the dominant form of traction. These vehicles are powered by a cable drum or overhead catenary. The motors convert the electrical energy into mechanical energy, driving the wheels. These motors are typically AC asynchronous motors or DC motors.

[0004] However, with the development of the market, the number of 45-ton subway construction tractors is increasing, but different tunnels require locomotives of different tonnages, resulting in many 45-ton locomotives being idle and unusable, causing a waste of resources. Utility Model Content
