    • 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.
    • 搅拌车包括:能够承载预拌混凝土的搅拌桶; 驱动装置,其使用工作油的油压驱动所述搅拌筒旋转; 压力传感器,其检测由所述驱动装置驱动的所述搅拌筒的驱动状态; 控制器,其通过将在所述混合器鼓中的所述预拌混凝土之后的所述压力传感器检测到的驱动条件的变化幅度与预定设定值进行比较来确定所述混合器鼓中的旋转不均匀度的大小; 以及通知装置,当所述控制器判断出由所述压力传感器检测到的所述驱动条件的变化幅度已经达到所述设定值时,通知驾驶员所述搅拌滚筒中的所述旋转不均匀度的大小达到允许值。
