A load-side crane is provided with: an outrigger device that is mounted on a vehicle and that includes a right outrigger and a left outrigger that can extend and contract in the vehicle width direction of the vehicle; an arm rotatably mounted on the vehicle; and a rotation angle calculation device for calculating the limit rotation angle of the arm on the basis of the jack reaction force of the overhang leg on the opposite side of the turnover. The overhang leg on the opposite side of the turnover is one of the right overhang leg and the left overhang leg, and is disposed on the opposite side of the arm in the vehicle width direction in a state in which the arm is rotated from the reference position.

    装载侧起重机具备:外伸支腿装置,被搭载于车辆,且包括能够在车辆的车宽方向上伸缩的右侧外伸支腿及左侧外伸支腿;臂,以能够回转的方式被搭载于车辆;以及回转角计算装置,基于翻倒相反侧外伸支腿的千斤顶反作用力,求出臂的极限回转角,该翻倒相反侧外伸支腿是右侧外伸支腿和左侧外伸支腿之中的、在臂从基准位置进行了回转的状态下在车宽方向上被配置在臂的相反侧的外伸支腿。
