Mixer truck with drum rotation unevenness determination

摘要

A mixer truck includes: a mixer drum capable of carrying ready-mixed concrete; a driving device that drives the mixer drum to rotate using an oil pressure of a working oil; a pressure sensor that detects a driving condition of the mixer drum driven by the driving device; a controller that determines a magnitude of rotation unevenness in the mixer drum by comparing a magnitude of variation in the driving condition detected by the pressure sensor with a predetermined set value after the ready-mixed concrete in the mixer drum has been discharged; and a notifying device that notifies a driver that the magnitude of the rotation unevenness in the mixer drum has reached an allowable value when the controller determines that the magnitude of the variation in the driving condition detected by the pressure sensor has reached the set value.

1. A mixer truck having a mixer drum that is capable of carrying ready-mixed concrete, comprising:
a driving device that is configured to drive the mixer drum to rotate using a fluid pressure of a working fluid; a driving condition detector that is configured to detect a driving condition of the mixer drum driven by the driving device; a controller that is configured to determine a magnitude of rotation unevenness in the mixer drum by comparing a magnitude of variation in the driving condition detected by the driving condition detector with a predetermined set value after the ready-mixed concrete in the mixer drum has been discharged; and a notifying device that is configured to notify a driver that the magnitude of the rotation unevenness in the mixer drum has reached an allowable value when the controller determines that the magnitude of the variation in the driving condition detected by the driving condition detector has reached the set value.
