Abstract: A machine for transferring pipe between the floor of a drilling rig and a pipe rack including a stationary trough positioned below the drilling rig floor and a movable trough aligned with the stationary trough and having one end resting on the drilling rig floor and the other end movable vertically relative to the end of the stationary trough nearest the drilling rig. An operator's cab is attached to and supported by the end of the stationary trough distant the drilling rig floor. The cab has a housing which is pivotally attached at its forward edge to the stationary trough whereby the housing may be pivoted forward 90.degree. onto the stationary trough for ease of transporting the machine. The operator's cab further includes a control panel mounted to the stationary trough and not pivotal with the housing. A lifting device attached underneath the stationary trough can cam the stationary trough up off of its support surface until it rests on rollers.

Abstract: An apparatus for transferring pipe between pipe racks and the drilling rig floor including a stationary trough located below and extending towards the drilling rig and a movable, inclined trough aligned with the stationary trough having one end supported on the drilling floor and the other end powered to move between a lower position for transferring pipe to and from the stationary trough and an upper position for transferring pipe to and from the drilling floor. Two pair of racking legs extending between the pipe racks and the fixed trough are provided. Each leg has a cradling lug which moves up and down the leg powered by a hydraulic cylinder, thereby lifting the pipe along the leg. Further, each leg is able to pivot in two directions about a pivoting structure. The pipe when moving in the troughs is held at one end by a shovel member which is engageable by the buggy traveling along the stationary trough and is also engageable by the carriage in the inclined trough.
