The invention provides a movable balance trolley device of a tower crane, which comprises a fixed counterweight, a movable balance trolley, a movable counterweight, a stroke limiter, a normally closed brake and a hydraulic driving device, the movable counterweight is fixed on the movable balance trolley, and the movable balance trolley can move back and forth on a balance arm. And a normally closed brake and a stroke limiter are mounted on the movable balance trolley. One end of the hydraulic driving device is connected with a support fixed on the balance arm through a pin shaft, and the other end of the hydraulic driving device is connected with the movable balance trolley. And the hydraulic driving device is connected and controlled by a circuit. The moment balance state of the two ends of the cargo boom and the balance arm of the tower crane can be automatically adjusted, and stable and safe operation of the tower crane is achieved.

    本发明提出了一种塔式起重机活动平衡小车装置,包括固定平衡重、活动平衡小车、活动平衡重、行程限位器、常闭式制动器、液压驱动装置,所述的活动平衡重固定在活动平衡小车上,活动平衡小车可以在平衡臂上来回移动。活动平衡小车上安装有常闭式制动器与行程限位器。液压驱动装置一端与固定在平衡臂上的支座通过销轴连接,另一端与活动平衡小车连接。液压驱动装置由电路连接控制。本发明能自动调节塔式起重机起重臂与平衡臂两端力矩平衡状态,实现塔式起重机平稳安全运行。
