[0047] At this time, the operator can sit on the seat 22, start the motor 12 first. The motor 12 drives the first transmission shaft 801 on the gearbox 8 to rotate through the connecting transmission assembly 13.

Subsequently, the control lever 20 is used to operate the front driving wheel 6 and the rear driving wheel 7 to rotate until the front driving wheel 6 moves to the front of the slope. At this time, the front fixed wheels 4 are on the slope. Subsequently, the front driving wheel 6 is retracted by the front telescopic assembly 2 to the same height as the front fixed wheels 4 and the rear fixed wheels 5. Then, the rear driving wheel 7 rotates to drive the lifting vehicle to move forward until the rear driving wheel 7 is in front of the slope. At this time, the front fixed wheels 4, the rear fixed wheels 5, and the front driving wheel 6 are all on the slope. Subsequently, the rear driving wheel 7 is retracted by the rear telescopic assembly 3 to the same height as the front driving wheel 6. At this time, the front fixed wheels 4, the rear fixed wheels 5, the front driving wheel 6, and the rear driving wheel 7 have the same height, and the operator can drive the lifting vehicle to move forward on the slope.
