Abstract
A tower segment erection tool having a frame with a first side, a second side showing in the opposite direction than the first side and a holding mechanism for holding the frame with its first side at the bottom of a tower segment to be erected. A first support element adjoins the frame's second side such that it is located substantially under a section of the tower segment's peripheral wall when the tool is attached to the tower segment to be erected. The first support element has a curved surface allowing a rolling motion of the tower segment erection tool A second support element adjoins the frame's second side and has a foot that is spaced from the curved surface of the first support element such that it is located substantially in the tower segment's centre axis and that it is further away from the tower segment's bottom in a direction parallel to the tower segment's centre axis than the curved surface when the tower segment erection tool is attached to the tower segment to be erected. The curvature of the first support element's curved surface is such that during erection of the tower segment the tower segment erection tool rolls about the curved surface until the foot of the second support element touches the ground.
