[0026] Specifically, the chassis 11 and the drive wheels 12 are fixedly connected to each other. The chassis 11 in this forklift is relatively heavy and is used for counterweight to maintain the stability of the entire forklift. Moreover, the design position of the drive wheels 12 is relatively compact, which can minimize the floor area occupied by the drive wheels 12 to adapt to a smaller space. The drive motor 22 drives the overall rotation of the turntable 21.
