ABSTRACT OF THE DISCLOSURE 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° 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. The machine may then be pulled or pushed along the catwalk or a flatbed on these rollers. Guide arms attached to the lifting device guide the stationary trough along the catwalk. Racking arms attached to the sides of the stationary trough move the pipe laterally between the stationary trough and the pipe racks. An adjustable pipe run-off assembly attached to the stationary trough adjacent the racking arms allows the pipe to be guided away from the racking arms to different positions on the pipe rack. The racking arms are adjustable in length and have a pivotal support plate secured at their end.
