34. 7 BASIC TORQUE MEASUREMENT Basic torque measurements are performed using a simple hydraulic measurement system A hydraulic load cell connects to a calibrated torque gauge through a reinforced flexible hydraulic hose The torque gauge is factory calibrated to display accurate torque measure ments for a tong or tong and backup assembly with a particular arm length The arm length is a measurement from the centre of the pipe or casing to the centre of the force being applied to the load cell Two load cell options are available A tension load cell is typically used with a suspended stand alone tong This application requires that the load cell be attached to the rear of the tong as part of the restraint line that opposes the force generated when the tong makes up or breaks out a joint A compression load cell is used in a tong and backup assembly and is typically located on the rear of the backup between the backup and a stationary frame The load cell must be located in the centre of the compression force vector generated between the backup and the frame Hydraulic force generated by a load cell is transmitted to the torque gauge via a reinforced flexible hydraulic line The hydraulic force is displayed as torque in units of Ft Lbs The torque gauge has a red peak torque indicator that tracks with the torque gauge needle to the point of highest torque and remains at the point of highest torque until manually reset Note that every model of ton

Routinely testing the sensor shutdown system operation before mobilizing and at each shift change ensures protection of drill floor personnel A rotating tong potentially stores a large amount of kinetic energy in the gear train Testing the sensor shutdown system by suddenly opening the tong door to stop rotation will generate a shock load that could result in catastrophic equipment failure not covered by the manufacturer s warranty and may present a hazard to personnel on the drill floor The following procedure outlines the correct safe procedure for testing the door sensor tong shutdown system on a McCoy power tong Using the correct testing procedure ensures the sensor shutdown system is fully functional without exposing the equipment to a shock load or personnel to a potential hazard The tests also verify that the shut down valve is positively sealing and rules out the possibility that contaminated hydraulic fluid or erosion is preventing the valve from completely shutting off the motor s supply of hydraulic fluid i Shift the tong to low gear see Section 2 H 3 ii Stop all tong rotation iii Open the tong door iv Gradually attempt to turn the tong using the rotation control handle Continue to gradually move the handle until the valve is fully stroked and hold for 30 seconds Verify the ring gear does not rotate while the rotation control is engaged PROCEDURAL NOTE a very small amount of ring gear movement is acceptable as the cartrid
