ABSTRACT:
A method of using an apparatus for handling heavy pipe is set forth. Pipe is rolled off the end of a pipe rack into a waiting elongate trough. The trough is moved on a pair of trolley cables extending from that area up towards a rig floor, the trolley cables being raised, and the trough being pulled along the trolley cables by means of a control cable which moves the trough toward the rig floor. At a registered location, the trough is stopped and a lock device is extended on generally horizontally positioned hydraulic cylinders. The lock device is brought down onto and locks around the upper portions of the pipe. The lock device is able to support the pipe as it is rotated upwardly toward the derrick and moved into an aligned position whereby the pipe is supported vertically on the lock device free of the trough and the lower end of the pipe hangs above the rotary table ready for threading in the next step of assembly of the pipe string.
