The invention relates to a linkage control braking system of a girder transporting machine. The linkage control braking system comprises air control devices, a circuit control device, a main machine foot braking device and a main machine braking main valve. An auxiliary machine foot braking device is arranged on an auxiliary girder transporting machine body. The connecting relationship between parts of the air control device of the auxiliary girder transporting machine body is the same as that between parts of the air control device of a main girder transporting machine body. A first switch module comprises a normally-open contact switch. The structure of a second switch module is the same as that of the first switch module. According to the linkage control braking system, air sources carried by trucks are used as power sources, pneumatic control is adopted, cost is saved, and the structure is compact; as wireless remote control is adopted, operation is convenient; as LED indicator lamps are arranged on electromagnetic valves respectively, it is guaranteed that an electric control system is safe and stable; linkage braking of the main girder transporting machine body and the auxiliary girder transporting machine body is achieved through pneumatic electromagnetic reversing valves; and as the LED indicator lamps are arranged on the corresponding electromagnetic valves, whether corresponding circuits are normal or not is monitored, and design is reasonable.
