Abstract:
A remote controlled tilting power swivel capable of being tilted to any angle up to an adjustable maximum tilt angle. The tilting power swivel angle of tilt can be adjusted to line up with pipe staged at various angles as required by different rigs. Adjusting the maximum extension of the tilt cylinder allows the power swivel to repeat a desired angle for the duration of a job. The system requires the addition of only one hydraulic fluid supply hose, thereby allowing a simple live hose reel with four hoses. The tilting power swivel promotes safety, efficiency, and saves time by eliminating the need for a stabbing man hanging in the derrick.
