There is described a device (1) for tensioning an elongated hoisting member (10), wherein said device (1) comprises: - a first friction-generating member (2) rotatably supported around a first support member (6); - a second friction-generating member (4) rotatably supported around a second sup¬ port member (8), said first and second friction-generating members (2, 4) being adapted to provide friction to the elongated hoisting member (10) when said first and second friction-generating members (2, 4) are pressed against each other with a por- tion of the elongated hoisting member (10) therebetween; and - a braking means (18) for braking the rotation of said first and second friction- generating members (2, 4) around said first and second support members (6, 8). There is also described a system including such a device (1), as well as a method for operating such a system.

    L'invention concerne un dispositif (1) pour tendre un élément de levage allongé (10), ledit dispositif (1) comprenant :- un premier élément de génération de frottement (2) solidarisé en rotation autour d'un premier élément de support (6) ; - un second élément de génération de frottement (4) solidarisé en rotation autour d'un second élément de support (8), lesdits premier et second éléments de génération de frottement (2, 4) étant conçus pour fournir un frottement à l'élément de levage allongé (10) lorsque lesdits premier et second éléments de génération de frottement (2, 4) sont appuyés l'un contre l'autre avec une partie de l'élément de levage allongé (10) placée entre les deux ; et - un moyen de freinage (18) pour freiner la rotation desdits premier et second éléments de génération de frottement (2, 4) autour desdits premier et second éléments de support (6, 8). L'invention concerne également un système comprenant un tel dispositif (1), ainsi qu'un procédé pour faire fonctionner un tel système.
