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 (16, 17) 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 (16, 17); 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 (16, 17); f) inserting core elements into the space defined by the pallet and the formwork elements (16, 17), 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 (16, 17), 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 (16, 17) 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 (16, 17); 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 (16, 17); f) inserting core elements into the space defined by the pallet and the formwork elements (16, 17), 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 (16, 17), 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,
