The present invention relates to a transit-mixer truck operating a mixing drum (20) by a hydraulic driving force using a main engine (12), a hydraulic pump (15), and a hydraulic motor (22). The transit-mixer truck comprises: an auxiliary operating unit (30) having an auxiliary engine (32) to provide the hydraulic driving force to the mixing drum (20); a detecting unit to detect a signal relating to an operating state (40) of the main engine (12) and the auxiliary engine (32); a controller (50) to operate the auxiliary engine (32) in a set condition while the main engine (12) stops. Accordingly, the mixing drum can constantly be operated by the auxiliary engine even if the main engine stops, thereby reducing fuel and man-hour work. |
