ABSTRACT:
A casing stabbing apparatus which includes a derrick bracket subassembly for attachment to a derrick, and a boom having an end pivotally connected to the bracket assembly for pivotation about a vertical axis and about a horizontal axis. A pair of arcuate casing gripping jaws is pivotally connected to the second end of the boom. A piston and cylinder assembly extends between the jaws to selectively converge and diverge the jaws. A second piston and cylinder assembly extends between the bracket assembly and the boom to elevate the boom by pivotation about a horizontal pivotal axis. A third piston and cylinder assembly extends between the bracket assembly and the boom to swing the boom laterally in pivotation about a vertical axis. A remote automatic control subassembly enables the casing stabbing operation to be carried out from a remote location by the use of a hand held wand.
