The invention relates to the technical field of operation machinery, and provides a boom structure, a tower crane and a control method of the tower crane, the boom structure comprises a boom, a driving device and a movable counterweight, the boom comprises a cargo boom and a balance arm, the movable counterweight is arranged on the cargo boom and/or the balance arm, and the driving device is connected with the movable counterweight. The driving device is in transmission connection with the movable counter weight, and the driving device is used for driving the movable counter weight to move in the length direction of the cantilever crane; the movable counterweight is driven by the driving device to horizontally move on the balance arm in the length direction of the arm frame, and/or the movable counterweight is driven by the driving device to horizontally move on the cargo boom in the length direction of the arm frame, so that in the hoisting process, the movable counterweight is driven by the driving device to horizontally move on the cargo boom in the length direction of the arm frame. And the balance moment of the balance arm in the arm support and the lifting moment of the lifting arm always reach dynamic balance, so that the risk of rollover of the tower crane is effectively avoided.

    本发明涉及作业机械技术领域,并提供了一种臂架结构、塔式起重机及其控制方法,臂架结构包括臂架、驱动装置和可移动配重,所述臂架包括起重臂和平衡臂,所述可移动配重设置于所述起重臂和/或所述平衡臂,所述驱动装置与所述可移动配重传动连接,所述驱动装置用于驱动所述可移动配重沿所述臂架的长度方向移动;本发明通过驱动装置驱动可移动配重在平衡臂上沿臂架的长度方向水平移动,和/或,通过驱动装置驱动可移动配重在起重臂上沿臂架的长度方向水平移动,以在起吊过程中,臂架中平衡臂的平衡力矩与起重臂的起重力矩始终达到动态平衡,进而有效避免塔式起重机出现侧翻的风险。
