PROBLEM TO BE SOLVED: To provide a hydraulic backhoe capable of warning not to interrupt crane work during a load suspended state.SOLUTION: A hydraulic backhoe is provided with: a lock switch 23 to detect an operation position of a gate lock lever 22; and a control section 36 to determine, when a crane mode is selected by a mode switch 37, if the hydraulic backhoe is in a load suspended state using a hook 16 and the gate lock lever 22 is operated to a position which allows an operator to get on/off and when the determination is affirmative, control a monitor 39 and a buzzer 40 to generate warnings.SELECTED DRAWING: Figure 3

    【課題】吊り荷状態でクレーン作業を中断させない様に注意を促すことができる油圧ショベルを提供する。【解決手段】油圧ショベルは、ゲートロックレバー22の操作位置を検出するロックスイッチ23と、モードスイッチ37でクレーンモードが選択された場合、フック16を用いた吊り荷状態にあり且つゲートロックレバー22が乗降許可位置に操作されたか否かを判定し、この判定が肯定された場合にモニタ39及びブザー40を制御して警報を出させる制御部36とを備える。【選択図】図3
