The invention discloses an anti-toppling loading manipulator. A mounting frame is located on one side of a main frame and is mounted on the main frame, the lower end of the mounting frame is providedwith a supporting arm extending in the direction away from the main frame, a striker plate is vertically arranged above the supporting arm and mounted on the mounting frame, an anti-toppling mechanismis provided with a rotating shaft arranged in a manner of being perpendicular to the direction of the striker plate, the anti-toppling mechanism is rotatably mounted on the mounting frame through therotating shaft, a first driving mechanism is connected with the anti-toppling mechanism to be used for driving the anti-toppling mechanism to rotate, the anti-toppling mechanism is provided with a stopping arm, and the stopping arm is arranged to be parallel to the striker plate. Through the above anti-toppling loading manipulator in optimized design, stacked cargoes are lifted up by the supporting arm wholly, the anti-toppling mechanism is rotated, the stopping arm is rotated downwards, the cargos are stopped between the stopping arm and the striker plate, and the cargoes are prevented fromtoppling over in the moving process.
