CONCRETE MIXER AND CONTROLS THEREFOR

摘要

A concrete mixing system includes a vehicle (10), a rotatable mixing drum (28) coupled to the vehicle, an incline and/or slump sensor, and a controller. The controller (140) is configured to effect a change of rotational speed of the rotatable mixing drum in response to a signal from at least one of the sensors indicating an increased likelihood of spillage of concrete from the rotatable mixing drum (28).
