To improve maintainability of a heat exchanger.SOLUTION: A revolving work machine comprises: an external cover 70 that forms a space for disposing equipment on a revolving base; an exhaust part disposed at a position on one lateral part side of an airframe on the external cover 70; and a cooling unit CU disposed at a position facing the exhaust part in the space. The cooling unit CU comprises: a frame body 98 having an opening; a heat exchanger CA disposed at a position on the exhaust part side and corresponding to the opening of the frame body 98; a fan F that is disposed on the exhaust part side of the heat exchanger CA so that an air intake side faces toward the heat exchanger CA side and an air exhaust side faces toward the exhaust part side; and a mounted part 105 that is disposed on the side opposite to the side on which the heat exchanger CA of the frame body 98 is disposed and detachably mounted with a filter 100 for capturing dust in the air sucked by the fan F to the opening side.SELECTED DRAWING: Figure 22

    【課題】熱交換器のメンテナンス性を向上させる。【解決手段】旋回作業機は、旋回台において機器を配置する空間を形成する外装カバー70と、外装カバー70における機体の一側部側の位置に設けられた排気部と、前記空間における排気部に臨む位置に配置された冷却ユニットCUと、冷却ユニットCUは、開口部を有する枠体98と、枠体98の排気部側且つ開口部に対応する位置に配置された熱交換器CAと、熱交換器CAの排気部側に、吸気側が熱交換器CA側を向き且つ排気側が排気部側を向くように配置されたファンFと、枠体98の熱交換器CAが配置されている側とは反対側に設けられた、ファンFによって開口部側に吸引される空気中の塵芥を捕捉するフィルタ100が着脱可能に装着される被装着部105と、を備えている。【選択図】図22
