    摘要: The present disclosure relates to the technical field of mechanical equipment for aerial works, in particular to a small scissor aerial work platform and a traveling chassis thereof. The traveling chassis includes a base (1) and oppositely-arranged left and right steering wheel assemblies (2). The base (1) is of a concave structure and a scissor-stored groove (11) with an upward opening is formed in the base. A left wheel set accommodating groove (12) and a right wheel set accommodating groove (13) which are used for accommodating the steering wheel assemblies (2) and provided with downward openings are further formed in a front end of the base (1), and a lower portion of the scissor-stored groove (11) is located between the left wheel set accommodating groove (12) and the right wheel set accommodating groove (13). According to further embodiments, the chassis further comprises left and right steering control mechanisms and each steering control mechanism comprises an electric push rod device (3).
