Shaker stations of the series GyroShake are used for the silent compaction of concrete in precast part manufacturing plants. The concrete for e.g. panel ceilings, garage floors, double-wall panels or railway sleepers is silently compacted in molds, with operational noise emission levels of below 70 dB (A). The system impresses with its high compaction performance, practically pore-free exposed concrete and short cycle times at < 70 dB (A). It can be integrated in pallet circulation systems and controlled by their master computer. The stations are individually assembled to meet the customer´s needs.
