Abstract: The systems, devices, and methods described herein relate to a modular gripperhead system for a drilling rig. The system includes a gripper having a first gripper arm and a second opposing gripper arm, each gripper arm having an inwardly facing gripping surface that forms at least a portion of a chamber sized to receive a portion of a cylindrical tubular, wherein the portion of the chamber has a longitudinal axis. The system also includes a grabber having a first grabber arm and a second grabber arm. Each grabber arm may be displaceable between a retracted position and an extended position in a direction along a first axis that is transverse to the longitudinal axis. The first and second grabber arms may be pivotable about a first and second pivot point between an open position sized to permit a portion of a cylindrical tubular to enter between the first and the second grabber arms and a closed position sized to secure a portion of a cylindrical tubular between the first and the second grabber arms.

Abstract: Apparatus and methods include a parking system for a drilling rig. The parking system includes a first track portion extending along a pathway between a well center and a V-door on a drilling rig and a second track portion extending in a transverse direction relative to the first track portion. A trolley is configured to carry a racking device and move along at least a portion of the first track portion and the second track portion between a position in the pathway between well center and the V-door on a drilling rig and a position offline and out of the pathway between well center and the V-door on a drilling rig.
