Abstract: An electronic control system comprises a first tubular handling tool, a sensor, and a controller. The controller is configured to control actuation of the first tubular handling tool in response to an electronic signal received from the sensor that corresponds to an operational characteristic of the first tubular handling tool. The electronic control system functions as an electronic interlock system to prevent mishandling of a tubular. A method of controlling a tubular handling tool comprises measuring an operational characteristic of the tubular handling tool, communicating the operational characteristic to a controller in the form of an electronic signal, and using the controller to control actuation of the tubular handling tool in response to the measured operational characteristic.

Abstract: The present invention generally relates to an apparatus for positioning a tool at a well site. The apparatus includes a first arm rotationally connected to a guide on a column. The apparatus further includes a second arm rotationally connected to the first arm. The second arm is also connected to a tool attachment member at a pivot point, wherein the pivot point is offset from the centerline of the tool. Additionally, the apparatus includes a flexible tension member having one end operatively connected to the guide and another end connected to the tool attachment member at a location closer to the centerline of the tool than the pivot point, wherein the flexible tension member is configured to maintain the tool in a specific orientation around the pivot point during the positioning operation. In a further aspect, a method of positioning a tool at a wellsite is provided.
