The invention relates to an aerial work platform provided with a pothole protection device and a railing door allowing users to get in easily. The aerial work platform comprises a traveling chassis and a lifting device. The lifting device comprises a scissors-type lifting structure and a working platform. The working platform comprises a fixed platform bottom plate, railing frames and the railing door. One side of the railing door is rotationally installed on the corresponding railing frame. The railing door is locked on the corresponding railing frame through a railing lock. The railing lock comprises a door lock rod, a movable buckle and a door lock catch. One end of the door lock rod is hinged to one side of the railing door, and the movable buckle and the door lock catch are fixed to the other side of the railing door. A movement space used for limiting the movement range of the door lock rod is formed between the movable buckle and the railing door. The door lock rod penetrates through the movement space. The door lock catch is fixed on the corresponding railing frame. The door lock catch is located below the other end of the door lock rod. The door lock catch is provided with a lock groove with an upper opening. The railing door of the working platform is convenient to open; besides, accidental looseness can be effectively prevented, and thus the safety performance is high.
