Abstract: A device is for vertical tool guiding for a drill floor. On the drill floor is arranged at least one rig. Each rig is arranged on a rig foundation supported on the drill floor rotatably about a first, vertical axis (A) and arranged to be able to displace a tool in a horizontal working sector (Sa, Sb, Sc) that in a vertical projection at least touches or cuts through the central axis (C) in a through drill floor opening. Each rig is provided with a vertical guide track.

Abstract: A rotary table device is provided with means arranged for suspension of a pipe string. The rotary table comprises a rotary ring arranged rotatably about the central axis of the rotary table. The rotary ring is formed by two or more ring sections, each connected to a system comprising a bearing housing section rotatable relative to a base section, a bearing housing groove being formed in a base contact surface on the bearing housing section and a corresponding base groove being formed in an opposing bearing housing surface in the base section. The grooves form a curve-shaped track for a roller body and the groove has a curvature center coinciding with the central axis of the rotary table. The rolling diameter of the roller body exceeds the collective depth of said grooves, and a channel connecting the end portions of the bearing housing groove is formed in the bearing housing section.
