Abstract: A method for lifting, stacking or otherwise manipulating a length of pipe is provided which includes the steps of providing a longitudinally orientated base frame; providing a movable carriage supported on the base frame, and providing a pipe lifting structure mounted to the carriage for independently supporting a length of pipe in a longitudinal position with respect to the base frame. The pipe lifting structure has first and second telescopically extendable lifting arm assemblies that are pivotally mounted to a longitudinally orientated pipe trough for supporting a length of pipe in the pipe trough. A means for pivotally raising and lowering the lifting arm assemblies and thereby said pipe trough and support length of pipe is provided. The method includes providing means for pivotally raising and lowering the lifting arm assemblies remotely located from the pipe lifting structure. Hydraulic cylinders and rams are provided to move the lifting structure.

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.
