PIPE TRANSFER SYSTEM

摘要

A pipe handling machine for moving well pipes arranged essentially horizontally and essentially parallel to one another on a deck, and including a carriage which may contain an operator's control cabin and is mounted by tracks for movement transversely of the pipes, with an arm projecting from the carriage and adapted to support a pipe from one of its ends as a cantilever, and with the arm being power actuable upwardly and downwardly to raise and lower a pipe and in its elevated position shift the pipe laterally with the carriage. The arm may deliver the pipe to or receive it from an inclined conveyor leading to the rig floor. Preferably, two such machines are provided for shifting pipes on two storage decks at different levels, and for delivering pipes to or from an intermediate conveyor system extending between the two decks.
