Abstract
A system for fastening climbing structures to vertical bodies, comprising fastening structures that allow a climbing structure to be moved in steps along a vertical body, such as a wind turbine tower, each fastening structure comprising a clamp jaw ( 1 ) with which it is pre-adjusted to the vertical body by a set of callipers ( 1.1 ), and a clamp ( 2 ) with which it is clamped to the vertical body by pads ( 4 ) which are joined to a hinged arm ( 6 ) and which are pressed by a webbing ( 7 ) against the surface of the vertical body.
