Support structure for concrete mixer vehicle

A concrete mixer vehicle comprising:

• a chassis having a frame;
• an engine coupled to the frame;
• a cab coupled to the frame, the cab defining an interior compartment;
• a drum assembly including:
• a mixing drum defining an aperture and an internal volume;
• a drum driver configured to selectively rotate the mixing drum relative to the chassis;
• and
• a hopper assembly configured to introduce materials into and allow the materials to flow out of the internal volume of the mixing drum;
• a front roller pedestal coupled to the frame and configured to support a front end of the mixing drum, the front roller pedestal including a pedestal frame, a first mounting bracket, a second mounting bracket, and a support member, the pedestal frame having an upper portion and a lower portion, the upper portion including a pair of drum drive rollers configured to receive and facilitate rolling of the mixing drum, the lower portion including a first interface joint coupled to the frame by the first mounting bracket and a second interface joint coupled to the frame by the second mounting bracket, the support member having a first end and a second end, the first end of the support member being coupled to the upper portion of the pedestal frame and the second end of the support member being coupled to the frame of the chassis, the support member being configured to provide support to the pedestal frame in a longitudinal direction with respect to a longitudinal axis of the frame;
• and
• a rear pedestal coupled to the frame and configured to support a rear end of the mixing drum.
