A lift-off control device, which is mounted on a crane having an arm and a hoist for lifting a wire rope and performs lift-off control for lifting a load, is provided with: a rotation detection unit for detecting the number of rotations of the hoist; a pressure detection unit that detects a pressure value of a fluctuating cylinder that fluctuates the arm; an estimation unit that estimates the undulating angular velocity of the arm on the basis of the detection values of the rotation detection unit and the pressure detection unit; and a control unit that controls the rising and falling operation of the arm on the basis of a target rising and falling angular velocity of the arm calculated from the detection value of the pressure detection unit and the estimated value of the estimation unit.

    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:旋转检测部,检测卷扬机的旋转数;压力检测部,检测使臂起伏的起伏油缸的压力值;估计部,基于旋转检测部及压力检测部各自的检测值估计臂的起伏角速度;以及控制部,基于根据压力检测部的检测值计算出的臂的目标起伏角速度、以及估计部的估计值,对臂的起伏动作进行控制。
