ABSTRACT:
A self-contained, freestanding, modular, portable pipe pick-up and laydown apparatus. The apparatus includes a movable carriage and carriage rail supported on base frame. The base frame includes means for moving the carriage along the length of base frame. The apparatus also includes a pipe trough supported on first and second telescoping pipe trough lifting assemblies pivotally mounted on the carriage. The pipe trough is semicircular in configuration which serves to cradle and manipulate a joint of pipe. Jacks are used to lift and tilt upward the telescoping pipe trough lifting assembles to raise the pipe trough and any supported pipe. The pipe trough may be leveled and otherwise manipulated by extension and retraction of the trough lifting assemblies. A hydraulic lift and detachable hinges are used to pivot the pipe trough on its edges as desired. The invention also provides a movable pipe jack and reversible pipe guides to facilitate the loading and unloading of pipe to and from the pipe trough.
