[0021] It should be noted that the top end of the right upper pressing plate 13 is fixedly connected with the first friction pad 14, and the bottom end of the left lower pressing plate 17 is fixedly connected with the second friction pad 18, so as to enhance the frictional damping of the right upper pressing plate 13 and the left lower pressing plate 17 and the guide frame 10, and further increase the stability of the vehicle body when the staff is on the vehicle body frame 1.

[0022] As a further embodiment of the present application, the vehicle body frame 1 is welded by rectangular tubes and angle steels, which increases the firmness of the vehicle body frame 1, and the top end of the vehicle body frame 1 is symmetrically welded with the guardrails 3 to prevent the staff from falling from the vehicle body frame 1.
