Abstract
A combination hydraulic pipe handler and power swivel for providing services normally requiring two machines, two hydraulic systems, two engines, two spaces at a rig site, and two costs to the user. Now only one machine is required. The combination hydraulic pipe handler and power swivel can pick up tubulars, present tubulars safely to the rig floor at an adjustable angle, and provide a tilting power swivel which tilts to the same adjustable angle allowing the rig operator to threadably engage tubulars and lift the tubulars to vertical. Tailing of tubulars with a rope and manpower is not required, thus the operation is much safer than normal.
