The invention relates to the technical field of cranes and particularly discloses a multi-suspension-arm tower crane. The multi-suspension-arm tower crane comprises a supporting frame and a fixing sleeve. A top plate is fixedly arranged on the top of the supporting frame. A second motor is fixedly installed on a rotating wheel of the top plate. An output shaft of the second motor is fixedly connected to the center position of the lower surface of a rotating seat. A fixing sleeve is fixed to the upper surface of the rotating seat. A double-spindle motor is installed in the fixing sleeve throughan installation plate. Movable arms are embedded in the left end and the right end of the fixing sleeve, and inner threads are arranged in the movable arms. An output shaft of the double-spindle motor is fixedly connected with two rotating threaded rollers, and the rotating threaded rollers are rotationally embedded in the movable arms and are provided with outer threads with opposite directions.Rotating wheels are rotationally arranged at the outer ends of the movable arms, and the top of the fixing sleeve is rotationally provided with a rotating roller. The center of the rotating roller iscoaxially connected with a first motor. The multi-suspension-arm tower crane has the beneficial effects of being simple in structure, convenient to operate, high in adaptability and convenient to implement and popularize.
