Tong Line Pull Gauges
Crown's tong torque and tong line pull gauges (CTT100 Series) are designed to indicate make-up or break-out torque for tool joints, drill collars, and drill string components, measuring in pounds of line pull. This system is used in applications where there are two or more sets of tongs being used with differing handle lengths. A 6” fluid-filled gauge reads the pounds of line pull from the tong handle. As the joints are made-up, the line pull is converted to hydraulic pressure within the cylinder, and sent to the gauge through the rubber hose. The gauge can then display this reading in measurements of line pull. The torque being applied can be determined by multiplying the gauge reading by the foot length of the tong handle. A large variety of systems (with up to 30,000 pounds of single line pull) are available in English, Metric, or dual scale systems.
