The invention relates to the technical field of tower cranes, and provides a movable arm tower crane, the movable arm tower crane realizes the swing of a lifting arm through a hydraulic cylinder, the lifting arm is also provided with an automatic counterweight module and a lifting hook module, the automatic counterweight module can drive a rope to pull a counterweight to move to a corresponding position according to the swing angle of the lifting arm, and the lifting hook module is used for lifting the lifting arm. Due to the design of the inclined plane, when the cargo boom is reset, the counterweight module can return to the initial position due to the gravity of the counterweight module, and the effect of flexible counterweight is achieved; the lifting hook assembly can move downwards and upwards towards the ground through the driving lifting mechanism, the lifting hook module can move back and forth in the length direction of the movable arm through the driving walking mechanism, and when the movable arm swings up and down, the lifting hook assembly can still be normally used at the moment and cannot collide with the movable arm.

    本发明涉及塔吊技术领域,提供一种动臂塔吊,该动臂塔吊通过液压缸来实现起重臂的摆动,该吊臂还拥有自动配重模块、吊钩模块,自动配重模块能够根据起重臂摆动的角度,从而驱动绳索牵引配重移动到相应的位置,并且斜面的设计还能够在起重臂复位的时候,配重模块因为自身的重力而回到初始位置上,实现了灵活配重的效果;通过驱动提升机构,吊钩模块能够往地面方向下行和上行,通过驱动行走机构,吊钩模块能沿动臂长度的方向往返运动,并且在动臂上下摆动时,此时吊钩组件仍可以正常使用,不会和动臂发生碰撞。
