Abstract

L'installation de forage selon l'invention comprend un mât comportant une partie fixe (11) le long de laquelle est montée coulissante une structure mobile portant une tête de fixation et d'entraînement en rotation d'un élément mené tel qu'une tige ou un train de tiges servant à réaliser un forage, l'entraînement de la structure mobile le long de la partie fixe (11) est assuré au moyen d'un mécanisme faisant intervenir au moins un vérin linéaire (V1, V2), axé parallèlement au mât, dont l'une des extrémités prend appui sur la partie fixe tandis que l'autre extrémité porte au moins une poulie (P1, P2) autour de laquelle passe au moins un lien dont une extrémité est solidaire de la partie fixe (11) tandis que l'autre extrémité est solidarisée à la structure mobile.
