A method for manufacturing a prefabricated concrete component, particularly a prefabricated concrete slab, wherein the component is manufactured in a formwork, wherein the component side, which in the installed state of the component forms the upper side of the component, faces the bottom of the formwork, wherein at least one lifting sleeve is inserted into the component during the manufacture of the component, wherein the component can be fixed on a transport device by means of the lifting sleeve, wherein the lifting sleeve has at least one first sleeve opening, at least one sleeve shaft for receiving a lifting key and a sleeve end lying opposite of the first sleeve opening, wherein the lifting sleeve has at least one cross-sectional widening in the form of a lifting chamber, and wherein the inside diameter (d k) of the lifting chamber is greater than the internal width (b s) of the sleeve shaft, wherein the lifting key is after at least partial curing of the component inserted into the sleeve shaft through the first sleeve opening, which is assigned to the side forming the underside of the component, and transferred into an anchoring position in the lifting chamber in order to remove the component from the formwork, and wherein the component is subsequently removed from or lifted out of the formwork by means of the lifting key, wherein the sleeve end is realized in the form of a second sleeve opening that is assigned to the upper side of the component, which in the installed state of the component faces away from the installation substructure, and accessible from the upper side of the component, and wherein the lifting chamber is respectively assigned to the sleeve end or the second sleeve opening, and wherein the distance between the lifting chamber and the sleeve end amounts to between 2% and 49% of the length of the lifting sleeve. wherein at least one lifting sleeve is inserted into the component during the manufacture of the component, wherein the component can be fixed on a transport device by means of the lifting sleeve, wherein the lifting sleeve has at least one first sleeve opening, at least one sleeve shaft for receiving a lifting key and a sleeve end lying opposite of the first sleeve opening, wherein the lifting sleeve has at least one cross-sectional widening in the form of a lifting chamber, and wherein the inside diameter (d k) of the lifting chamber is greater than the internal width (b s) of the sleeve shaft, wherein the lifting key is after at least partial curing of the component inserted into the sleeve shaft through the first sleeve opening, which is assigned to the side forming the underside of the component, and transferred into an anchoring position in the lifting chamber in order to remove the component from the formwork, and wherein the component is subsequently removed from or lifted out of the formwork by means of the lifting key, wherein the sleeve end is realized in the form of a second sleeve opening that is assigned to the upper side of the component, which in the installed state of the component faces away from the installation substructure, and accessible from the upper side of the component, and wherein the lifting chamber is respectively assigned to the sleeve end or the second sleeve opening, and wherein the distance between the lifting chamber and the sleeve end amounts to between 2% and 49% of the length of the lifting sleeve.
