The invention discloses a movable arm tower crane backward tilting preventing control system. The movable arm tower crane backward tilting preventing control system comprises a display device, a steering device, a control device and a lifting variable-frequency driving device. The display device, the steering device and the lifting variable-frequency driving device are respectively connected withthe control device. The display device is used for setting parameters and displaying the working mode of a tower crane and operation parameters. The steering device is used for outputting tower craneoperation motion control signals. The control device is used for receiving a working mode signal input by the display device, a lifting control signal input by the steering device and an angle signalinput by a sensor, and sending a lifting operation control command to the lifting variable-frequency driving device. The lifting variable-frequency driving device is used for executing the lifting operation control command and controlling the corresponding action of a boom. By means of the movable arm tower crane backward tilting preventing control system, the movable arm tower crane has an anti-backward tilting control function, and the purpose of intelligent and humanized anti-backward tilting control of hoisting operation is achieved.
