ABSTRACT:
A concrete forming apparatus comprises a support table for holding a pallet in a generally horizontal orientation. A vertically movable mold table engages the pallet to place a mold carried in the mold table on top of the pallet. A dispensing hopper fills the mold with concrete. A vertically movable platen then engages the mold to contact and compact the concrete therein. The platen includes a plurality of air cylinders for securely holding the mold to the pallet during the concrete compaction process.
