The invention discloses a pneumatic monorail crane stable downhill control system, which comprises a constant-speed brake control unit, a brake control unit, a brake cylinder and a brake device, the constant-speed brake control unit comprises a constant-speed brake control valve, a pressure reducing valve, a one-way valve, a tee joint and a constant-speed brake switch, and the brake control unit comprises a brake control valve and a brake switch. The brake switch is connected with a control terminal of the brake control valve, the normally-open end of the brake control valve is connected with an air outlet of the brake cylinder, the normally-closed end of the brake control valve is connected with an air inlet of the even brake control valve, the normally-closed end of the even brake control valve is connected with the pressure reducing valve, and the pressure reducing valve is connected with the tee joint through the one-way valve. The tee joint is connected to the air inlet of the brake cylinder, the constant-speed brake switch is connected with the control end of the brake control valve, and the brake cylinder is installed on the brake device. The speed of a monorail crane is adjusted in real time through the constant-speed brake control unit, the downhill speed can be controlled according to different loads and gradients, and safety and high efficiency are achieved.
