The invention provides a stepless speed regulating control system of a pneumatic monorail crane. The stepless speed regulating control system consists of an air source processing system, a speed regulating reversing handle, a pneumatic motor power system and a pressure flow speed regulating system, wherein the air source processing system consists of an oil-water separator, a pressure reducing valve, a filter and an atomized lubricator; the speed regulating reversing handle is integrated by control handles of two pressure adjusting valves and an auxiliary reversing valve; the pressure flow speed regulating system consists of four speed regulating valves; and compressed air is supplied to a pneumatic motor, a cylinder and the speed regulating reversing handle for use by the air source processing system. The control system can precisely control the air pressure and flow to realize the stepless speed regulating power walking and the brake stopping of the pneumatic monorail crane, and can realize slow starting and braking to prevent quick starting/stopping phenomenon, so that the wear of a brake friction wheel is reduced, the monorail crane can operate more smoothly, and the stepless speed regulating purpose of the monorail crane can be realized; and the stepless speed regulating control system improves the operation reliability and safety of the monorail crane.
