  "abstract": "40 A lifting bail removably insertable into and lockable in a void former, the lifting bail comprising: a main stem insertable into the void former, the main stem including an upwardly extending head that includes: (a) a vertically extending inner wall that partially defines a vertically extending central locking pin channel, (b) a horizontally extending 5 planar wall, and (c) a vertically extending wall that extends upwardly from the planar wall, wherein the planar wall and the vertically extending inner wall define a housing chamber; a rotatable locking pin insertable into the void former; a locking pin handle connected to the locking pin; a locking indicator, wherein the housing chamber at least partially holds the locking indicator; a biasing member journaled about the locking pin and positioned to 10 bias the locking indicator toward a visible position to indicate that the locking pin is in a locked position, wherein the housing chamber at least partially holds the biasing member; and a lifting handle connected to the locking pin.",
