A lift-off control device, which is mounted on a crane having an arm and a hoist for lifting a wire rope, performs lift-off control for lifting a load, and is provided with: a load detection unit for detecting a load acting on the arm; and a control unit for controlling the lifting operation of the hoist and the raising operation of the arm, the control unit controlling the raising operation of the arm by a control signal to suppress the swing of the lifting load. The control signal is generated on the basis of a time change in a detection value of the load detection unit and is obtained by applying a filter that attenuates a frequency component in a predetermined range.

    一种吊离地面控制装置,其被搭载于具有臂以及提升钢缆的卷扬机的起重机,并进行起升载荷的吊离地面控制,该吊离地面控制装置具备:荷重检测部,对作用于臂的荷重进行检测;以及控制部,对卷扬机的提升动作及臂的仰起动作进行控制,控制部通过如下的控制信号,对臂的仰起进行控制来抑制起升载荷的摆动,该控制信号是基于荷重检测部的检测值的时间变化而生成且应用了使规定范围的频率成分衰减的滤波器而得到的控制信号。
