<p>An elongated mold box (40) encloses a removable rectangular pallet (82) and has a center portion pivotally supported by a carriage (35) which is supported for vertical movement by a pair of vertical guide posts (38) mounted on a frame (12). Hydraulic cylinders (56, 64) are connected to move the carriage vertically relative to the frame and pivot the mold box relative to the carriage for tilting the mold box between a vertical concrete filling position and a horizontal position for stripping a molded concrete article from the mold box. The pallet is supported within the mold box by a generally flat tray member (105) which is guided by parallel rails (111, 112) within the mold box and aligned horizontal guide rails (158) on a run-out platform (150). The mold box also carries a hydraulic cylinder (120) for moving the tray member between a retracted position within the mold box and an extended position on the run-out platform.</p> |
