Abstract
A pipe handling catwalk is provided for moving tubulars or pipe to and from a work floor of well drilling or service rigs. The catwalk includes a variable height V-door for guiding pipe to the work floor. The V-door is made of a series of sequential pivotally attached segments that can extend from, and retract into, the catwalk at an angle relative to the catwalk along a guide track disposed at an end of the catwalk.
