 High level of automation:
With the Carousel process, triple or quadruple moulding troughs are circulated.
Before the concrete is poured, tensioning wires are fitted and tensioned in the moulding troughs.
After pouring, the moulding troughs are stored in climatic chambers until the concrete has cured
sufficiently to permit the tension to be transferred from the trough to the sleepers. After tension transfer,
the sleepers are de-moulded. The moulds are cleaned and returned for the next manufacturing cycle.
