ABSTRACT:
An apparatus for making a plurality of formed concrete products. The apparatus comprises a platform having a series of mold cavities, wherein the platform is attached to a vibrator and a hydraulic lift system. The hydraulic lift system lifts and inverts the platform, molds, and cured concrete products for easy removal. The apparatus also comprises a reinforcing bar support system which suspends the reinforcing bars from tapered pins extending into the wet cement, thus eliminating the need for placing reinforcing bar supports on the bottom of the mold cavity.
