摘要： A hydraulic excavator includes an undercarriage having a crawler and a rotating superstructure. The rotating superstructure includes a plate-shaped rotating frame, an engine, a fuel tank a counterweight and a fuel line. The engine is mounted inside the rotating frame. The fuel tank is disposed on one side of the engine. The counterweight is supported on the rotating frame to the rear of the engine, and disposed so that a bottom end portion faces a rear end surface of the rotating frame with a gap interposed therebetween and the gap is open to the atmosphere. The fuel line is connected to the fuel tank and disposed in the gap between the rear end surface of the rotating frame and the bottom end portion of the counterweight.
