There is disclosed a clamp, a self-advancing climbing device including two such clamps, and a method of coupling such a clamp to a tubular. In one embodiment of the invention, there is disclosed a clamp (1) for a tubular, in particular a thin-walled tubular such as the tower (3) of a wind-turbine. The clamp (1) comprises at least one clamp member in the form of a friction pad (9) adapted to grip the tower (3), and at least one flexible elongate energising element in the form of a tendon (16) adapted to exert a force on the friction pad (9) to urge the pad (9) to grip the tower (3), whereby the pad (9) and the tendon (16) are adapted to exert a substantially uniform radial clamp load on the tower (3).
La présente invention concerne une fixation, un dispositif d'ascension à avance automatique comprenant deux telles fixations et un procédé de couplage d'une telle fixation à un élément tubulaire. Dans un mode de réalisation de l'invention est présentée une fixation (1) pour un élément tubulaire, en particulier un élément tubulaire à paroi mince, tel que la tour (3) d'une éolienne. La fixation (1) comprend au moins un élément de fixation sous forme de patin de frottement (9) adapté pour adhérer à la tour (3) et au moins un élément d'actionnement oblong flexible sous forme de tendon (16) adapté pour exercer une force sur le patin de frottement (9) afin de forcer le patin (9) à adhérer à la tour (3), moyennant quoi le patin (9) et le tendon (16) sont adaptés pour exercer une charge de fixation radiale sensiblement uniforme sur la tour (3).
