(EN)Disclosed herein is a raisable substructure (100) of a drilling rig (200) that includes first and second substructure boxes (101, 102). The first and second substructure boxes (101, 102) of the raisable substructure (100) each include, among other things an upper box (101u, 102u) and a lower box (101L, 102L), wherein each of the upper boxes 101u, 102u) is adapted to be raised above a respective lower box (101L, 102L). The disclosed raisable substructure (100) also includes a movable center floor section (120) that is adapted to be supported by the upper boxes (101u, 102u) of the first and second substructure boxes (101, 102), wherein the movable center floor section (120) is further adapted to be slidably moved between the upper boxes (101u, 102u) during assembly of the drilling rig (200).
