Abstract:
A pipe handling system comprises a carriage having an upper surface adapted to support a tubular. The carriage comprises a first section and a second section. The first and second sections are pivotally coupled together for rotation about a pivot axis. The carriage is movable relative to a base and configured such that the leading end of the carriage is elevated as the carriage is advanced. An actuator is coupled between the first and second sections. The actuator is operable to pivot the second section relative to the first section about the pivot axis. In some embodiments the carriage is configured with a positive kink to deliver tubulars to a rig floor and with a negative kink to deliver tubulars to an online or offline stand building system. In some embodiments a live surface on the carriage is controllable to reduce or eliminate swinging of tubulars as they are transferred to or from the drill rig.

Claim (Index 1):
A method for pipe handling in drilling, the method comprising:\n grasping a first end of a tubular with an elevator; changing an elevation of the first end of the tubular by moving the elevator; while changing the elevation of the first end of the tubular, allowing a second end of the tubular to rest on a live surface and operating the live surface to control motion of the second end of the tubular relative to a well center.
