Abstract
Abstract A TRUCK MIXER HAS A MIXING DRUM MOUNTED WITH ITS AXIS OF ROTATION OFFSET LATERALLY OF THE CENTERLINE OF THE TRUCK. THE DRUM IS OFFSET IN THE DIRECTION OPPOSITE THAT IN WHICH THE CONCRETE INGREDIENTS ARE MOVED WHILE BEING MIXED AND, SINCE MIXING IS GENERALLY DONE IN TRANSIT, THE OFFSET MOUNTING HAS THE EFFECT OF MAINTAINING THE CENTER OF GRAVITY OF THE INGREDIENTS MORE NEARLY ON THE CENTERLINE OF THE TRUCK DURING MIXING AND THEREBY MINIMIZING LATERAL INSTABILITY OF THE TRUCK MIXER IN TRANSIT.
