Abstract

An exhaust treatment unit includes a selective reduction catalyst device for treating exhaust gas from an engine. The exhaust treatment unit is arranged in the engine compartment. A reducing agent injection device is attached to the exhaust treatment unit. The reducing agent injection device injects a reducing agent fed to the selective reduction catalyst device. A reducing agent tank and a reducing agent feed pump are arranged outside the engine compartment. The reducing agent tank stores the reducing agent. The reducing agent feed pump feeds the reducing agent from the reducing agent tank to the reducing agent injection device. A reducing agent pipe connects the reducing agent feed pump and the reducing agent injection device with each other. A rotating frame includes a tube- shaped frame. The reducing agent pipe is arranged so as to extend from the reducing agent feed pump through the interior of the tube- shaped frame to the reducing agent injection device.
