ABSTRACT:
An automated well servicing system comprised of computer controlled tong assemblies, a remote controlled robotic racking system and unique slips and backup clamps. The system has a pair of tong assemblies for automatically disconnecting or connecting rods or tubes. Each tong assembly is pivotally mounted on the frame of a vehicle for deployment once the vehicle is parked at a well head and includes power tongs, backup clamps and slips mounted on hydraulically operated carriers for positioning over a well head. A robotic rod tubular handler controlled by a joy stick mounted on the waist of a floor man permits remote racking of rods and tubes. A slip assembly is provided comprised of a pair of housings forming a conical cavity and a conical mandrel having pins or slugs that clamp a tubular string when the two housings are pressed together. The slips are also constructed to maintain the clamping force on a string until a hoist and elevator lifts the string a short distance activating a proximity switch to release the string. The system also includes a unique elevator head having interchangeable plates to change the system from handling rods to handling tubes.
