SURROUNDING MONITORING DEVICE FOR WORK MACHINE
To provide a surrounding monitoring device for a work machine, capable of appropriately setting a movement limit range of a traveling body even in a stopped state.SOLUTION: A surrounding monitoring device for a work machine is equipped with a driving assistance control device 104 that limits a traveling operation of a traveling body 2. This driving assistance control device 104 sets a left coordinate system H1 and a right coordinate system H2 at positions offset by a predetermined amount in the left-right direction of the traveling body 2 from a reference Cartesian coordinate system whose origin is the rotation center O of a revolving body 3, and sets the coordinates of an obstacle 300 detected by an obstacle detection sensor 9 using these coordinate systems H1 and H2 to calculate an operation limit range that limits the traveling operation of the traveling body 2, and limits the traveling operation of the traveling body 2 when it is determined that the traveling body 2 has entered the operation limit range.SELECTED DRAWING: Figure 5
【課題】停止状態でも走行体の動作制限範囲を適切に設定することができる作業機械の周囲監視装置を提供する。【解決手段】作業機械の周囲監視装置は、走行体２の走行動作を制限する運転支援制御装置１０４を備えており、この運転支援制御装置１０４は、旋回体３の旋回中心Ｏを原点とする基準の直交座標系を、走行体２の左右方向に所定量だけオフセットした位置に左側の座標系Ｈ1と右側の座標系Ｈ2とを設定し、これら座標系Ｈ1と座標系Ｈ2を用いて障害物検出センサ９で検出された障害物３００の座標を設定することにより、走行体２の走行動作を制限する動作制限範囲を算出し、走行体２が動作制限範囲内に侵入すると判定した場合に、走行体２の走行動作を制限する。【選択図】図５
