Machine for fabricating concrete beams or joists, has one of vibrators operable by low power within front region of compaction mold and half-rotational to provide various vibration points within mold

摘要

The machine includes a concrete hopper, a compaction mold, an adjuster for outlining the concrete beams, and two vibrators both equipped with transmission systems. One of the beams is operable by low power and is half-rotational around its axis to provide various vibration points in the mold. Furthermore, the mold is progressively widened at the concrete exit, and is anchored on a frame via wedge-like supports.
