A rope traction device includes a sheave having an annular rope receiving groove and being driven and rotated with a traction rope received in the rope receiving groove to cause the traction rope to be wound on the sheave and the rope traction device thereby moves along the traction rope. The sheave includes a pair of side walls made of an elastic material and formed integrally with the sheave for formaing the rope receiving groove. The interval between inner surfaces of the side walls in a rope holding portion is made smaller than the diameter of the traction rope by a predetermined value. The rope receiving groove may be formed in a U-shaped section, a V-shaped section or a section which is a combination of the U-shaped section and the V-shaped section.
Dispositif de traction par câble comportant une poulie à gorge entraînée en rotation par un câble de traction passant dans la gorge autour de la poulie, de manière que le dispositif se déplace le long du câble. La poulie comporte une paire de flasques en matériau élastique formés à même la poulie et définissant la gorge de passage du câble. L'intervalle entre les faces opposées des flasques dans la partie recevant le câble est inférieur au diamètre de ce dernier d'une valeur déterminée. La gorge peut présenter une section en U, en V ou une combinaison des deux formes.
