The 7 ton battery locomotive is divided into normal type with first class transmission, thicken wall type, normal class with second class transmission and double-engine-driving type. Its voltages are 250V and 550V, the speed turning way is resistance and IGBT chopping speed regulation. Its characteristic: short wheelbase, high stiffness, good cushioning property. The double engine drawing machine is a new product, it is indirect contact control, can be synchronization controlled. The mechanical brake is installed as well as the electric brake and the air brake, big drawing power, high speed and good stopping performance.
