The invention discloses an electric forklift, an axle box and a lubricating structure of the axle box. In the structure of the axle box, the axis of a transmission shaft of a first gear and the axis of a drive half shaft are located in a plane C, the distance between the transmission shaft and the drive half shaft is d, an input gear is located on the rear upper portion of the drive half shaft, the horizontal distance between the axis of the input gear and the drive half shaft is 100%-110% of d, and the vertical distance between the input gear and the plane C is 40%-50% of d; a duplicate gear shaft is located under the plane C, the horizontal distance between the duplicate gear shaft and the drive half shaft is 45%-55% of d, and the vertical distance between the duplicate gear shaft and the plane C is 5%-15% of d; when the plane C where the axis of the transmission shaft and the axis of the drive half shaft are located is horizontal, the liquid surface in the axle box is higher than the plane C and lower than an upper end of a communication hole. By means of the electric forklift, the axle box and the lubricating structure of the axle box, a differential mechanism assembly, gears and bearings are well lubricated. Besides, a connection sleeve connected with a motor does not need to be sealed.
