  • Hydraulic excavator
    Patent number: 8955638
    Abstract: An exhaust processing unit includes a selective catalytic reduction apparatus which processes exhaust from an engine. A reducing agent injection apparatus is attached to the exhaust processing unit. The reducing agent injection apparatus injects a reducing agent which is supplied to the selective catalytic reduction apparatus. The reducing agent tank and the reducing agent supply pump are arranged outside the engine compartment. The reducing agent tank retains the reducing agent. The reducing agent supply pump supplies the reducing agent from the reducing agent tank to the reducing agent injection apparatus. The reducing agent pipe connects the reducing agent supply pump and the reducing agent injection apparatus. The revolving frame includes a pipe frame. The reducing agent pipe is arranged from the reducing agent supply pump to the reducing agent injection apparatus so as to pass through the inner space of the pipe frame.
