1. A method for production of a plurality of concrete cast elements of prestressed concrete in a long bed which is a multiple of a length of a concrete cast element, comprising installing separating elements in the long bed to define the length of each of the concrete cast elements to be cast, characterized in that a first separating element and a second separating element for defining the length of each concrete cast element together with a tensioning device with tensioning elements for tensioning said concrete cast element between the first and second separating elements are mounted in the long bed, whereupon each concrete cast element is cast between the first and second separating elements and is at least partially hardened in the long bed.
