The invention discloses an aerial work platform. The work platform comprises a fixed platform and a movable platform, the fixed platform and the movable platform are in sliding fit with a guide rod through a guide rail, a pulley which can slide in the guide rail and a pin shaft which is used for hinging the pulley to the guide rod are arranged at one end of the guide rod, and the work platform further comprises abutting-against pieces which are installed at the two ends of the pin shaft and can prevent the side wall of the guide rail from being in contact with the side wall of the guide rod; when the pulley reaches the preset position, the abutting-against pieces can move in the axis direction of the pin shaft. When the pulley is within the offset-permitted range, the circumstance that friction force between the abutting-against pieces and the guide rail is generated, so that the frictional wear is caused can be avoided through the abutting-against pieces, and meanwhile the relative sliding between the guide rail and the guide rod is guaranteed. After the pulley breaks away from the preset position, the abutting-against pieces are located between the side wall of the guide rail and the pin shaft, and the side wall of the guide rail can be prevented from abutting against the guide rod so that the abutting-against problem between the guide rod and the guide rail can be effectively solved.
