SMALL-SIZED HYDRAULIC EXCAVATOR
PROBLEM TO BE SOLVED: To excellently keep workability when executing side ditch digging work in the vicinity of an obstacle.SOLUTION: Left-right obstacle sensors 13 and 14 are provided on left-right side surfaces 9A1 and 9B1 of a left exterior cover 9A, and whether or not an obstacle exists around an upper turning body 4, is determined on the basis of a distance up to the obstacle detected by the left-right obstacle sensors 13 and 14. A vehicle body controller 27 determines whether or not the obstacle exists around the upper turning body 4 with a reference distance (XL+α) made by adding a constant distance α to a distance XL between a left end part 12C1 of a bucket 12C and the left obstacle sensor 13 as a threshold value YL in a state of moving a work front 12 in parallel to the left side, and determines whether or not the obstacle exists around the upper turning body 4 with a reference distance (XR+α) made by adding the constant distance α to a distance XR between a right end part 12D1 of the bucket 12C and the right obstacle sensor 14 as a threshold value YR in a state of moving the work front 12 in parallel to the right side.SELECTED DRAWING: Figure 3
【課題】 障害物の近傍で側溝掘り作業を行うときの作業性を良好に保つ。【解決手段】 左外装カバー９Ａの左，右の側面９Ａ１，９Ｂ１に、左，右の障害物センサ１３，１４を設け、左，右の障害物センサ１３，１４によって検出された障害物までの距離に基づいて、上部旋回体４の周囲に障害物が存在するか否かを判定する。車体コントローラ２７は、作業フロント１２を左側に平行移動させた状態で、バケット１２Ｃの左端部１２Ｃ１と左障害物センサ１３との間の距離ＸLに一定距離αを加えた基準距離（ＸL＋α）を閾値ＹLとして上部旋回体４の周囲に障害物があるか否かを判定し、作業フロント１２を右側に平行移動させた状態で、バケット１２Ｃの右端部１２Ｄ１と右障害物センサ１４との間の距離ＸRに一定距離αを加えた基準距離（ＸR＋α）を閾値ＹRとして上部旋回体４の周囲に障害物があるか否かを判定する。【選択図】 図３
