The invention discloses an upper platform extending limiting device of an aerial work platform. The upper platform extending limiting device comprises an upper platform body and an extending part. The extending part is installed in the upper platform body and can slide in the length direction of the upper platform body. A limiting assembly is arranged between the upper platform body and the extending part. The limiting assembly comprises a locking mechanism and a limiting block. The locking mechanism is installed on the extending part. The limiting block is installed on the upper platform body. The locking mechanism slides to the limiting block of the upper platform body along the extending part to achieve limiting fixing. The upper platform extending limiting device is simple in structure and convenient to control, and the construction safety of personnel is improved.
