Summary:PROBLEM TO BE SOLVED: To provide a hydraulic shovel capable of reducing thermal effects on reductant and of protecting a reductant pipe.SOLUTION: An exhaust treatment unit includes a selective reduction catalyst device for treating exhaust gas from an engine. The exhaust treatment unit is arranged in an engine compartment. A reductant injection device is mounted in the exhaust treatment unit. The reductant injection device injects reductant supplied to the selective reduction catalyst device. A reductant tank and a reductant supply pump are arranged outside the engine compartment. The reductant tank stores the reductant. The reductant supply pump supplies the reductant from the reductant tank to the reductant injection device. A reductant pipe connects the reductant supply pump to the reductant injection device. A revolution frame includes a tubular frame. Te reductant pipe is arranged extending from the reductant supply pump through the internal of the tubular frame to the reductant injection device.
