Zusammenfassung:	Pipe handling apparatus and methods intended to facilitate the transportation of pipe between a rig floor and a rack of pipe. The pipe handling apparatus comprise in general a loading mechanism, which transports pipe between the pipe handler and a rig, and a racking mechanism, which transport pipe between a rack and the loader. The racking mechanism is adapted to selectively transport pipe from and deliver it to various levels in a rack of pipe. The racker comprises a pair of elevators, each of which has a pipe rest which is moveable between a hold position, in which pipe may be received therein and is restricted from rolling out of the pipe rest, and a release position, in which release position pipe may roll out of the pipe rest.
