  • Torque calibrating system
    Patent number: 10451513
    Abstract: A torque calibrating system that includes a power tong, a load cell assembly, and a torque arm having first and second ends, wherein the first end is adapted to impose a load on the load cell assembly when the power tong is actuated to impose a torque on the second end. The system also includes a hydraulic system that is adapted to actuate the power tong, wherein the hydraulic system includes a pressure gage that is adapted to measure a hydraulic pressure in the hydraulic system when the power tong is actuated, the measured hydraulic pressure corresponding to the load imposed on the load cell assembly and to the torque imposed on the second end of the torque arm.
    Type: Grant
