Concrete Plant Precast Technology
The tension reversal process is initiated via a semi-automated tension release unit and the prestress released into the concrete sleeper. The turnover beam then turns the mold by 180°, before an electric lifting device removes the sleepers from their mold. The mold is then turned back by 180° and returned to the mold circulation.
