Abstract:
A combination tubular handler and power swivel unit having an extendable trough to raise a tubular to a rig floor height without extensions. A raising leg is connected with the trough assembly through an easily installed height adjustment pin which requires no dangerous pinning. A following leg is pivotably coupled with an end of the trough assembly. This handler also moves the power swivel and other miscellaneous tools and equipment to the rig floor without winches or cables. A hydraulic swivel rack allows parking the swivel out of the way in a storage location when not in use.
