To provide a moment limiter device for boom work machine and a boom work machine equipped with the moment limiter device which can reduce the swaying of the suspended load that occurs when the boom is stopped during swinging.SOLUTION: A performance boundary line setting unit 104 sets a virtual straight line passing through the grounding coordinates calculated by a relative coordinate calculation unit 103 and the turning center of a boom 5 as a performance boundary line L for each of a plurality of outriggers. A response control line setting unit 106 sets as a response control line C the virtual straight line in which the performance boundary line L set by the performance boundary line setting unit 104 is shifted to the side where the rated load performance corresponding to the working posture of the boom work machine is higher. A response process control unit 200 turns the boom 5 at a lower turning speed than the required turning speed, which is a turning speed determined solely from the required values of the operator and others, when it determines that the boom 5 is turning between the response control line C and the performance boundary line L.SELECTED DRAWING: Figure 4

    【課題】旋回中のブームを停止させた際に発生する吊荷の揺れを低減させることが可能な、ブーム作業機用モーメントリミッタ装置と、ブーム作業機用モーメントリミッタ装置を備えたブーム作業機を提供する。【解決手段】性能境界線設定部104が、相対座標演算部103が演算した接地座標とブーム5の旋回中心とを通る仮想直線を、複数のアウトリガ毎に性能境界線Lとして設定し、対処制御線設定部106が、性能境界線設定部104が設定した性能境界線Lをブーム作業機の作業姿勢に対応する定格荷重性能が高い側へシフトさせた仮想直線を、対処制御線Cとして設定し、対処処理制御部200が、対処制御線Cと性能境界線Lとの間でブーム5が旋回していると判断すると、オペレータ等の要求値のみから決まる旋回速度である要求旋回速度よりも低い旋回速度で、ブーム5を旋回させる。【選択図】図4
