To provide a technology that can complete oil supply in a relatively short time in a fuel tank device of a construction machine including a main fuel tank and an auxiliary fuel tank.SOLUTION: A fuel tank device of a hydraulic shovel includes: a main fuel tank 5 provided at a deck; an auxiliary fuel tank 6 provided at the deck near the main fuel tank 5; and an oil supply connection pipe 7 which is arranged in the deck below the main fuel tank 5 and the auxiliary fuel tank 6 and connects a bottom surface 5B of the main fuel tank 5 with a bottom surface 6B of the auxiliary fuel tank 6. The main fuel tank 5 is formed with an oil supply port 51H for supplying a fuel. An oil sump tank 55, which is elongated in a vertical direction and preferentially filled with the fuel in the main fuel tank 5, is installed below the oil supply port 51H. A main fuel tank 5 side end part of the oil supply connection pipe 7 is configured to lead to the oil sump tank 55.SELECTED DRAWING: Figure 3

    【課題】主燃料タンクと補助燃料タンクとを備える建設機械の燃料タンク装置において、比較的短時間に給油を完了することが可能な技術の提供。【解決手段】油圧ショベルの燃料タンク装置は、デッキに設けられる主燃料タンク5と、主燃料タンク5の近傍においてデッキに設けられる補助燃料タンク6と、主燃料タンク5及び補助燃料タンク6の下側のデッキ内に配索され、主燃料タンク5の底面5Bと補助燃料タンク6の底面6Bとを連結する給油連結管7とを備える。主燃料タンク5には、燃料を給油するための給油口51Hが形成され、給油口51Hの下側には、鉛直方向に長尺な油溜槽55であって主燃料タンク5において優先的に燃料が充填される油溜槽55が設置されている。給油連結管7のうち主燃料タンク5の側の端部は、油溜槽55に通じるように構成されている。【選択図】図3
