Abstract

The invention relates to an electric forklift, and discloses a small and light electric forklift. The small and light electric forklift comprises a gantry, a frame, a fork carrier. An electronic steering and driving system is arranged at the bottom of the frame and comprises a driving motor, a steering motor, a main gear, a pinion, a steering potentiometer and a driving wheel, the main gear and the pinion are respectively connected to lower sides of the driving motor and the steering motor correspondingly, the driving wheel is arranged below the main gear, and the steering potentiometer is arranged below the pinion. The gantry arrangement is optimized, and front wheels are mounted on the gantry, so that the arm of force of load is minimized. A fingertip operation handrail arranged on the right side brings convenience for users to operate. Design of back legs of a safety frame is omitted, and only two front legs of the safety frame are connected with the frame, so that visual field of operators is wider and is free of blocking when in backing of the forklift, and the electric forklift is reasonable in design and easy to manufacture. In addition, since the electric forklift adopts the electric steering and driving integrated system, electric driving and electric steering are integrated.
