ABSTRACT:
A method for the production of prestressed concrete products and a plant for implementing the method. Moulds provided with pretensioned wires are moved through fixed casting machines into a hardening space. In the hardening space, the combination of mould and product is lifted sideways from the casting line before hardening, using synchronised lifting equipment. The combination may be stacked for space economy. After hardening, the product is removed from the mould using the same lifting equipment. The moulds are returned to the beginning of the casting line, during which stage they are cleaned and refurbished. The products are transferred to cutting and finishing stations.
