摘要:
A first tubular handling tool comprises an electronic control system, a sensor, and a sensor. 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 tubular handling system comprises a bail assembly and is configured to move a tubular relative to the tubular handling tool. A first sensor is configured to transmit a signal to the electronic control system corresponding to an angular position of the bail assembly, wherein the electronic control system is configured to actuate the bail assembly based on the angular position. Furthermore it is claimed a method of actuating a bail assembly of a tubular handling tool wherein an electronic signal is received from a first sensor corresponding to an angular position of the bail assembly relative to the tubular handling tool. A valve is actuated which controls fluid communication to a piston/cylinder assembly that actuates the bail assembly based on the angular position. In a next step the method actuates the bail assembly between a location beneath the tubular handling tool and a location outward of the tubular handling tool.
