Development direction: development direction of automobile transportation: increase the load capacity of automobiles; improve the structure of automobiles, develop electric wheel vehicles with dual energy sources; improve road quality to reduce tire wear and damage of parts; strengthen maintenance and overhaul of automobiles; Organizational scheduling to improve the effective operating rate of the car; combined transportation mode of the car and other modes of transportation. Railways: Railway transportation equipment is developed for locomotives with high traction, high efficiency, low energy consumption and vehicles with large capacity. Tape transportation: The tape machine is developing in the direction of high power, high speed and large inclination to meet the needs of large open pit mines, especially deep open pit mines.
