Abstract
A manipulator apparatus carries tools for connecting drillpipes to the drillstring in a wellbore on a drilling platform. A telescopically extendable horizontal work arm is carried on a telescopically extendable vertical column, and the tools are to be mounted on a free end of the work arm. The column is manually rotatable about a vertical axis. The column and the work arm are each respectively formed of a fixed element and a telescopically extendable element. The fixed element is preferably formed of two U-profile members arranged back-to-back, and the extendable element includes an H-profile member with its web received between the webs of the two U-profile members. This forms a telescopic slide bearing of the H-profile member sliding along the two U-profile members. The hydraulic cylinders are received in the recessed spaces of the profile members.
