ABSTRACT:
A concrete mixer truck frame is distorted when a concrete truck traverses a rough road and when the vehicle turns. Flexible mounting of pedestals which support the mixer drum accommodates distortion of the frame yet provides a rigid platform for the mixer drum. Each pedestal includes an upright frame with lower ends connected to side frame members with self aligning bearings. A central portion of a pedestal is flexibly connected to an upper part of a diagonal link with self aligning bearings. The truck frame includes "C" shaped cross members connected to the side frame members. A lower end of the diagonal link is flexibly connected to one of the cross members so that the load passes through the shear center of the "C" shaped cross member.
