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.

    本发明公开一种动臂塔机防后倾控制系统,包括显示装置、操纵装置、控制装置和起升变频驱动装置,所述显示装置、操纵装置和起升变频驱动装置分别与控制装置连接;所述显示装置用于参数设置、显示塔机工作模式及运行参数;所述操纵装置用于输出塔机运行动作控制信号;所述控制装置用于接收显示装置输入的工作模式信号、操纵装置输入的起升控制信号和传感器输入的角度信号,并向起升变频驱动装置发出起升运行控制命令;所述起升变频驱动装置用于执行起升运行控制命令,并控制起重臂相应动作。本发明使动臂塔机具有防后倾控制功能,实现了吊装作业防后倾控制智能化、人性化的目的。
