Problems solved by technology

[0002] The power source of common electric forklifts on the market is generally composed of three DC motors, one is a walking motor, one is a lifting motor, and the other is a steering motor. Due to the use of multiple motors, the power of this forklift is high. (total power is about 12KW), high energy consumption, short battery life, low efficiency, very complex electronic control device, high failure rate; and because there are many power sources, so there are many vibration sources, which are very easy to occur with the battery box and the frame Resonance seriously affects the use of electric forklifts
