The invention discloses an expandable and foldable work platform which comprises a work platform bottom frame, side brackets, side upper doors and flexible handrails, wherein through the rotatable connections between the side brackets and the work platform bottom frame, the rotatable connections between the side upper doors and the side brackets, the sliding connections between the flexible handrails and the side brackets, the sliding connections between the flexible handrails and the side upper doors, and the mechanical limiting and reinforcing of the components, the expansion and folding of the work platform are realized, so that the height of the work platform is low enough in a folded state and meets the work requirement in an unfolded state, namely, the height is 500 mm or below in the folded state and is 1100 mm or above in the unfolded state, so as to solve the problem that the work is inconvenient to carry out by several workers with multiple devices simultaneously as the conventional work platform is relatively large in mounting space, the work haulage motor is ultrahigh, and the traditional work platform is relatively small in bearing capacity. The expandable and foldable work platform has the advantages of being simple in structure, easy to dismount, convenient to operate, safe, reliable and small in mounting space, and is especially suitable for railway work implements.
