A draw-works comprising: an elongated hoisting member; two drums for storing and reeling the elongated hoisting member; and a rotation means for rotating the drums by means of a shaft to which the drums are connected, wherein: the first end of the elongated hoisting member is connected to one drum; and the second end of the elongated hoisting member is connected to the second drum, wherein: at least one of the drums is selectively connectable to and disconnectable from the rotation means so that, when one of the drums is disconnected from said rotation means, the shaft is freely rotatable inside the disconnected one of the drums and all torque from said rotation means is provided to the other drum, and, when both drums are connected to said drive means, the torque from said rotation means is shared between both drums.

    Il est décrit un treuil de forage qui comprend les éléments suivants : un élément de levage allongé; deux tambours servant à stocker et à enrouler lélément de levage allongé; un moyen de rotation servant à faire tourner les tambours grâce à un axe auquel les tambours sont attachés. La première extrémité de lélément de levage allongé sattache à un premier tambour, tandis que la deuxième extrémité de lélément de levage sattache au deuxième tambour. Au moins un tambour peut se coupler de manière sélective à un moyen de rotation de manière à permettre à laxe de tourner librement à lintérieur dun tambour lorsque ce dernier se découple et à transmettre la totalité du couple produit par cette rotation à lautre tambour. Lorsque les deux tambours se couplent au moyen dentraînement décrit, le couple produit par la rotation se partage entre les deux tambours.
