Abstract:
A method for handling pipe includes orienting a pipe having first and second ends so that the second end of the pipe is positioned vertically above the first end, and while the pipe is oriented with the second end positioned vertically above the first end, gripping onto the pipe proximate the first end with a lift jaw assembly that is coupled to a lift arm assembly. The pipe is vertically misaligned at a substantially non-zero misalignment angle relative to the first end of the pipe while gripping the pipe with the lift jaw assembly, wherein vertically misaligning the pipe includes rotating the lift jaw assembly relative to the lift arm assembly.
