  • Load detection and indicator apparatus for well tubing or the like
    Patent number: 4842058
    Abstract: A load cell apparatus especially suitable for detecting and indicating loads on tubing injected into or withdrawn out of a well with an injector apparatus. The load cell apparatus is located longitudinally directly below the injector apparatus to avoid angling of the tubing as it is run into, or pulled out of, a well. Two gauges are provided to independently indicate positive and negative loads on the tubing and to facilitate determining whether the pipe has hit an obstruction in a well. A fluid chamber is provided to support the weight of the tubing head, facilitating accurate load cell readings.
