ABSTRACT:
A method and device for use in regulating torque application to a drill string when joining drill string segments using a tong and winch combination. A tension gauge and an angle measuring gauge continuously read tension on the winch line and the angle between the winch line and the tong arm. Actual torque on the drill string segments is calculated thereby and used to deactuate the winch clutch when a desired torque has been applied. A display and printer can display and print torque information as the process of make up proceeds.
