To prevent the attachment from being damaged or broken due to a large lateral load being applied to the attachment caused by swing operation of the upper swing body.SOLUTION: A swing control unit 802 of a control unit 80 receives a swing command signal output from an operation unit 81, and controls a swing drive unit 7S so that an upper swing body 12 swings relative to a lower traveling body 14 in response to the swing command signal. Further, the swing control unit 802 controls the swing drive unit 7S so that a swing angular velocity of the upper swing body 12 does not exceed a maximum swing angular velocity set by an angular velocity setting unit 801, and also outputs an auxiliary command signal for reducing the swing angular velocity of the upper swing body 12 when an actual swing angular velocity of the upper swing body 12 approaches or exceeds the maximum swing angular velocity.SELECTED DRAWING: Figure 3

    【課題】上部旋回体の旋回動作によってアタッチメントに大きな横荷重が加わり当該アタッチメントが損傷、破損することを抑止する。【解決手段】制御部80の旋回制御部802は、操作部81から出力された旋回指令信号を受け入れ、当該旋回指令信号に対応して上部旋回体12が下部走行体14に対して旋回するように旋回駆動部7Sを制御する。また、旋回制御部802は、上部旋回体12の旋回角速度が角速度設定部801によって設定された最大旋回角速度を超えないように旋回駆動部7Sを制御するとともに、上部旋回体12の実旋回角速度が前記最大旋回角速度に近接した又は前記最大旋回角速度を超えた場合に上部旋回体12の旋回角速度を低下させるための補助指令信号を出力する。【選択図】図3
