Title: MIXER VEHICLE AND MIXER VEHICLE MANAGEMENT SYSTEM
Abstract:
[Problem] To provide a mixer vehicle and a mixer vehicle management system with which it is possible to assess whether or not water has been added to a concrete mix. [Solution] The mixer vehicle 100 according to an embodiment of the present invention is equipped with a mixer drum 2, a driving device 4, a pressure sensor 4a, and a slump-evaluating section 111. The driving device 4 comprises a fluid circuit for generating a driving force for rotating the mixer drum 2. The pressure sensor 4a detects information (mixer drum driving pressure) relating to the driving force. The slump-evaluating section 111 evaluates temporal changes in the slump of the concrete mix in the mixer drum 2 on the basis of the output of the pressure sensor 4a.
