Abstract: Concrete structural members are cast in a metal mold form which comprises side members closed off by a horizontally extending resilient pallet. The side members have affixed thereto at their lower ends adjustable swivel arm actuating mechanisms adapted to flex the side members laterally away from one another to enable stripping of the cast member from the form. The resilient pallet forms the bottom surface of the mold form and etablishes a seal to prevent slurry leakage. The pallet is supported by a roller transfer assembly that enables the cast member to be transported to another operating station after the cast member has been stripped from the form. The transfer assembly is adjustable in height by means of a swing arm assembly which in addition to setting the depth of the casting also causes the cast member to be elevated clear of the form to enable it to be removed therefrom.
