    Jaw Availability The following table lists all jaw die kits that are available as standard stocked sizes for this model of tong. McCoy Drilling & Completions | Farr offers a good selection of standard jaw sizes. However, please note that we can custom-engineer and manufacture any size of jaw within the range of the tong.

  • Page 28: Tong Rig-Up & Leveling

    McCoy Drilling & Completions recommends using dual backup (snub) lines of sufficient strength to withstand the force imparted by the maximum rated torque of the tong in use. Calculate the force on the snub lines by dividing the maximum torque of the tong by the tong’s torque arm (expressed in feet).
  • Page 29 KT14”-50K Tong & o etuP PeRation Suspension & Tong Restraint (Continued): Snub lines must be securely connected to the rear of the tong, and tied off to a suitable anchor. One snub line must be secured to the load cell, which is then secured to the rear of the tong. The side of the tong the load cell connects to is dependant upon whether make-up or break-out activities are underway.

  • Page 30: Tong Leveling

    KT14”-50K Tong & o etuP PeRation Tong Leveling The tong must be leveled side-to-side and front-to-rear before placing into service. The following guidelines will assist you when leveling your tong. Support the tong by the chain sling. Preset the positions of the side chains by rotating the turnbuckles on each side chain hanger until the eye bolts are about half-way engaged in the turnbuckle.

    KT14”-50K Tong & o etuP PeRation Valve Operation (Continued): The following illustration demonstrates the type and effect of the hydraulic valves with which this tong is may be equipped. TONG MOTOR This is a proportional valve. Pushing the valve handle forward will cause the tong motor to rotate in a clockwise direction (as seen from the top of the tong).

  • Page 33: Shifting Gears

    KT14”-50K Tong & o etuP PeRation Shifting Gears The shifting shaft has three “detent” positions identifying the low speed/high torque position, the “neutral” or free-spinning position, and the high speed/low torque position. The detent strength may be adjusted by releasing the locknut on the detent tube and increasing or relaxing pressure on the detent spring.

  • Page 34: General Operational Comments

    KT14”-50K Tong & o etuP PeRation General Comments Position rotary gear in contact with both idler gears when breaking out joints or collars where high torques are required. When making-up integral (shouldered) joints, it is essential to make up the last turn of the threads in low gear. This reduces the tendency of an instant stop or a sudden increase in torque, which induces extremely high stresses on the gear train.
