PROBLEM TO BE SOLVED: To hold a state where a cover that covers a loaded apparatus is closed.SOLUTION: In a small-sized hydraulic shovel 1, between a counter weight 7 and a rear face part 15B of a cab 15, an engine cover 23 is provided so as to be opened/closed in a vertical direction and at a rear lower side of the cab 15 and between the cab 15 and a rotary frame 6, a heat exchange device cover 28 is provided. The heat exchange device cover 28 has a horizontally opened structure in which a front end 28C in a longitudinal direction is defined as a support point and a rear end 28D becomes a free end, such that the heat exchange device cover can be rotated in a horizontal direction relatively to the rotary frame 6. At a rear end side of the heat exchange device cover 28, a lock mechanism 32 for heat exchange device cover is provided for holding the heat exchange device cover 28 in a closed state. In a state where both the heat exchange device cover 28 and the engine cover 23 are closed, the engine cover 23 covers the rear end 28D of the heat exchange device cover 28 and the lock mechanism 32 for heat exchange device cover from a rear side.SELECTED DRAWING: Figure 10

    【課題】 搭載機器を覆うカバーを閉じた状態に保持する。【解決手段】 カウンタウエイト7とキャブ15の後面部15Bとの間には、エンジンカバー23を上下方向に開閉可能に設け、キャブ15の後下側でキャブ15と旋回フレーム6との間には、熱交換装置カバー28を設けた小型の油圧ショベル1において、熱交換装置カバー28は、前後方向の前端28Cを支点とし後端28Dが自由端となって旋回フレーム6に対して水平方向に回動可能となった横開き構造とし、熱交換装置カバー28の後端側には、熱交換装置カバー28を閉じた状態に保持する熱交換装置カバー用ロック機構32を設け、熱交換装置カバー28とエンジンカバー23とが共に閉じられた状態では、エンジンカバー23が、熱交換装置カバー28の後端28Dと熱交換装置カバー用ロック機構32とを後方から覆う構成とする。【選択図】 図10
