ABSTRACT:
The invention relates to an apparatus for moving an Iron Roughneck into position to allow making-up or breaking-out of threaded joints in a drill string. The apparatus may also be used to move other drilling equipment into position on the centerline of the well or at mouse holes. A self-balanced, dual synchronized parallelogram arm is utilized to accomplish the movement of the devices. Hydraulic or pneumatic cylinders are used for extension and retraction of the arm rather than to support the tool. The arm may hold the tool in any position without cylinder assistance. The linkage in the synchronized parallelogram may be accomplished by gears, links, slots, or rollers.
