Abstract
A pipe handling device for mounting to use with a top drive and possibly a pipe engaging apparatus, includes a link arm having a first end pivotally connectable to move with the top drive and an outboard end pivotally connectable to a pipe elevator segment, and a drive system to drive the outboard end of the link arm at least between a lower position and a raised position. A pipe handling system and method may include or employ the pipe handling device.

34. A method for handling pipe in a rig, the rig including a top drive with a pipe engaging apparatus secured therebelow and a link arm on the pipe engaging apparatus and capable of pivoting relative to the pipe engaging apparatus, the method comprising:
- using the link arm to pick up a pipe from a pipe supply, hoisting the top drive in the rig such that the pipe is rotated to a substantially vertical position while remaining engaged by the link arm, positioning a lower end of the pipe onto a joint positioned in the rotary table such that the pipe is supported thereby, slidably holding an upper portion of the pipe with the link arm and lowering the top drive until the upper portion of the pipe is engaged by the pipe engaging apparatus.

38. A method for handling pipe in a rig, the rig including a top drive with a pipe engaging apparatus secured therebelow to define a main axis of the rig, the method comprising:
- providing a link arm mounted by a pivotal connection to move with the top drive, the link arm driven to pivot about its pivotal connection through a plane of rotation at least between a lowered position and a raised position and substantially stabilized when in the lowered position against moving out of the plane of rotation, using the link arm to pick up a pipe from a pipe supply, hoisting the top drive in the rig such that the pipe is rotated to a substantially vertical position while remaining engaged by the link arm, positioning a lower end of the pipe section onto a joint positioned in the rotary table such that the pipe is supported thereby, slidably holding an upper portion of the pipe with the link arm and lowering the top drive until the upper portion of the pipe is engaged by the pipe engaging apparatus.
