The invention discloses a luffing jib tower crane with a self-balancing mechanism. The luffing jib tower crane comprises a tower body, a control room, a suspension arm, a connecting frame and a fixing frame, the tower body is of a steel frame structure, a top plate is fixedly connected to the top end of the tower body, limiting rods are installed at the four corners in the tower body correspondingly and connected with one another through reinforcing supporting rods arranged in a linear array, fixing rods are fixedly connected to the outer surfaces of the limiting rods, and the outer side ends of the fixing rods are fixedly connected with the inner surface of the tower body; a round hole is formed in the middle of the top plate, and a bearing is installed in the round hole formed in the middle of the top plate. When the crane works, the counterweight part can be automatically adjusted according to the weight of lifted goods, so that the dynamic balance between the suspension arm and the counterweight part can be ensured, meanwhile, the stability of the rotating speed of the suspension arm can be ensured in the rotating process of the crane, and the dynamic balance among the suspension arm, the control room and the counterweight part can be kept; therefore, the safety of the crane during working is ensured.

    本发明公开了具有自平衡机构的动臂塔式起重机,包括塔身、控制室、吊臂、连接架和固定架;塔身:为钢架结构,塔身的顶端固定连接有顶板,塔身的内部四角分别安装有限位杆,且限位杆之间通过呈线性阵列设置的加固支杆相互连接,限位杆的外表面固定连接有固定杆,且固定杆的外侧端与塔身的内表面固定连接,顶板的中部开设有圆孔,且顶板的中部所开设的圆孔的内部安装有轴承。该起重机在工作时能够根据起吊货物的重量对配重部位进行自动调节,进而能够保证吊臂与配重之间的动态平衡,同时该起重机在旋转的过程中能够保障吊臂转速的稳定,且能够保持吊臂与控制室、配重部位之间的动态平衡,进而保证起重机在工作时的安全性。
