Method for the production of concrete hollow elements with the following steps, in particular in the circulation method: a) providing a pallet ; b) transporting the pallet to a plotter station where markings are applied to the pallet; c) applying formwork elements to the pallet , wherein the transverse formwork elements are composed of two parts and contained with openings, and wherein the longitudinal formwork elements comprise thrust gears, d) transporting the pallet to a reinforcement station in which tensioning wires are inserted and prestressed in the space defined by the pallet and the formwork elements ; e) transporting the pallet to a concreting station in which at least a first layer of concrete is filled into the space defined by the pallet and the formwork elements ; f) inserting core elements into the space defined by the pallet and the formwork elements , wherein the core elements are inserted and stored from above in the transverse formwork elements: g) filling at least one further layer of concrete into the space defined by the pallet and the formwork elements , h) transporting the pallet to a smoothing station in which the surface of the concrete hollow elements to be produced are smoothed by a pull-off device; i) transporting the pallet to a curing station where the concrete is cured, and j) transporting the pallet to a relaxation station in which the tensioning wires are relaxed, in particular, simultaneously, wherein at step d), the tensioning wires are fastened in a clamping yoke , which is moved to the application of the preload relative to the pallet in a first direction pointing from the concrete hollow element to be produced, and wherein after the application of the preload in the tensioning wires at least one holding bracket and/or at least one hydraulic punch between the clamping yoke and the pallet is introduced. a) providing a pallet ; b) transporting the pallet to a plotter station where markings are applied to the pallet; c) applying formwork elements to the pallet , wherein the transverse formwork elements are composed of two parts and contained with openings, and wherein the longitudinal formwork elements comprise thrust gears, d) transporting the pallet to a reinforcement station in which tensioning wires are inserted and prestressed in the space defined by the pallet and the formwork elements ; e) transporting the pallet to a concreting station in which at least a first layer of concrete is filled into the space defined by the pallet and the formwork elements ; f) inserting core elements into the space defined by the pallet and the formwork elements , wherein the core elements are inserted and stored from above in the transverse formwork elements: g) filling at least one further layer of concrete into the space defined by the pallet and the formwork elements , h) transporting the pallet to a smoothing station in which the surface of the concrete hollow elements to be produced are smoothed by a pull-off device; i) transporting the pallet to a curing station where the concrete is cured, and j) transporting the pallet to a relaxation station in which the tensioning wires are relaxed, in particular, simultaneously, <EOS>
