ABSTRACT:
Apparatus for precasting concrete products wherein dry mix is deposited in casting cavities defined by mating upper and base form sections, vibrated and/or pressure compacted, and the upper form section removed immediately for curing of a free standing green cast product. A single upper form section cooperates with a number of base sections and the latter are used to transport the green cast products for curing. Automatically separable base section parts are also employed for the transport of cured products. Forms are adapted for fork lift handling and include high intensity vibrators, sight openings for ascertaining a cavity full condition, closure plates for fill openings, pressure applying and finishing devices, and sectionalized construction for various size products. Casting machine includes mix delivery apparatus and form handling apparatus for upper and base form sections for automated casting and transfer of green cast products for curing.
