Abstract: A pipe puller removably couples to a pipe handler skate using two manually removable pins. The pipe puller includes at least one slide and linear bearing combination, a skate plate affixed adjacent a first end of the slide and interposed between a front skate face and a pipe in the skidway, a pipe grasp pivotal between a first position disengaged from the pipe and a second position engaged with the pipe, linkage coupling the skate plate to pipe grasp and converting reciprocal movement of the skate plate into rotary movement of the pipe grasp, and a puller stop bracket secured to the pipe handler. A pair of force threshold activated pipe grasp assists retain the pipe grasp in either pipe-engaged or pipe-disengaged position until a force threshold is reached greater than and separate from the static and dynamic coefficients of friction of the various pintles and linear bearings.

Abstract: Stands (43) of multiple lengths of drill pipe, for oil and gas drilling are individually supported in a storage bin (28, 29) in an array of plural layers of plural numbers of stands. The individual stands are held in cooperating notches (41, 42) in vertically aligned support sleepers (38, 39) so that each stand experiences loads due only to its own weight and motions of a bin frame (13) where, as preferred, the frame is supported on a drillship deck (12). Sleepers between stand layers are indexable between positions in the array and outside the array. A bridge crane (32, 33) spans the length of the bin and is moveable transversely above it. The bridge crane carries vertically movable magnetic lifting heads (47) for lifting, holding and releasing an individual pipe stand. The crane can move a stand between a supported position in the bin array and a supported position on a power-driven carriage (18, 49) which is movable along a path along an upper part of a side of the bin (28, 29).

Abstract: The trailer is operative to carry tubulars (drill collars or drill pipe) to a service rig and raise them to the level of the rig floor so that the rig elevators can latch onto them and stand them up in the derrick. The trailer has a roller-equipped carriage operative to move along tracks supported by and extending lengthwise of the trailer frame. An elongate flat bed is pivotally mounted at its front end to the trailer frame. The bed's rear end can be raised by a scissor hoist connected between the carriage and the rear end of the bed. The bed has grooves extending lengthwise thereof in which the tubulars sit. Thus the trailer can be backed up to within a few feet from the well. The rear end of the bed can be raised and the carriage and bed can be advanced rearwardly to bring the rear ends of the tubulars within reach of the rig elevators.
