More specifically, the width of the lower step 102 is smaller than the width of the upper step 101. In the embodiment shown in fig. 1, since there is a gap between the lower step 102 and the chassis 2, if the width of the lower step 102 is equal to or greater than that of the upper step 101, the space occupied by the lower step 102 in the lateral direction is greater than that occupied by the upper step 101 in the lateral direction, so that the space occupied by the whole machine in the lateral direction is increased, and the parts of the lower step 102 extending in the lateral direction may hinder the operation of workers in an expanded area. Therefore, the width of the lower step 102 is smaller than that of the upper step 101, and the above-described problem can be solved.

In a preferred embodiment, more specifically, the upper ladder 101 comprises an upper pedal 1015, the lower ladder 102 comprises a lower pedal 1023, and the edges of the upper pedal 1015 and the lower pedal 1023 facing away from the chassis 2 are provided with upwardly extending baffles 103. In the embodiment shown in fig. 1, when the worker steps on the upper pedal 1015 and the lower pedal 1023, the baffle 103 can prevent the feet of the worker from sliding out of the upper pedal 1015 and the lower pedal 1023, thereby improving safety.

The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, for the system embodiment, since it is substantially similar to the method embodiment, the description is simple, and for the relevant points, reference may be made to the partial description of the method embodiment.

The above description is only an example of the present application and is not intended to limit the present application. Various modifications and changes may occur to those skilled in the art.
