    ING DEVICES, UNLESS THOSE MODIFICATIONS ARE PERFORMED BY MCCOY. McCoy Global recommends following an industry-accepted standard such as OSHA, ASME B30.9-2006, or manufacturer’s guidelines when performing any rigging and overhead lifting. Use by untrained persons is hazardous. Improper use will result in serious injury or death.
  • Page 27 2.C.1 Inspection Of Slings McCoy strongly recommends the following practices: A complete inspection of new load-bearing devices and attachments shall be performed by a qualified, designated person prior to initial use. Each link and component shall be examined individually, taking care to expose and examine all surfaces including the inner link surface.
  • Page 28 • McCoy recommends that an anti-corrosive agent such as Tectyl ® 506 be applied to all external surfaces. Refer to manu- facturer data sheets for proper application and safety information. Allow the anti-corrosive coating ample time to dry - refer to manufacturer data sheets for drying times at room temperature.

  • Page 29: Illustration 2.D.1: Lift Cylinder & Spring Hanger Installation

    The lift cylinder is not orientation-specific; that is, the lift cylinder will function the same way independent of which end is connected to the crane and which end is connected to the main lifting lug of the tong (or the spring hanger, if used). However, McCoy recommends orienting the lift cylinder with the hydraulic hose connection at the bottom of the cylinder to ensure the hose is not stressed when cylinder is at full extension.

    Additionally, incorrectly sized jaws will cause the pipe to be off-centre relative to the backup, resulting in eccentric rotation and potential pipe thread damage. Use of jaws not manufactured by McCoy is not recommended, and may result in jaw slippage jaw failure, or damage to the camming surfaces of the rotary gear.
  • Page 40 The suspension line may be extended over a pulley and balanced by a counterweight equal to the weight of the tong, or simply tied off in the derrick to form a dead line. When using a dead line arrangement it is necessary to use a McCoy spring hanger assembly (see specification page for recommended spring hanger).

The following guidelines will assist you when leveling your tong. FAILURE TO PROPERLY LEVEL TONG MAY RESULT IN JAW SLIPPAGE OR FAILURE OF JAW COMPONENTS Place a level axially (side to side) across the tong, ensuring that it is parallel with the surface of the tong.
  • Page 43 2.H.2 Operator Safety McCoy recommends that a hazard assessment of the work area be performed by a designated safety representative before commencing operations. A designated safety representative is responsible for verifying that all operators have adequate equip- ment and safety training.

  • Page 44: Illustration 2.H.1: Tong Rotation Control Valve

    2: C & o KT14-75K HYDRAULIC POWER TONG ommissioning peration 2.H.3 Valve Operation (Continued): 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). This is the desired direction of rotation for making up a joint. Pulling the valve handle in the opposite direction results in counter-clockwise rotation, which is the desired direction of rotation for breaking out a joint.

  • Page 45: Illustration 2.H.3: Tong Manual Shift Control

    2.H.5 Pre-Operational Checks McCoy recommends that the following pre-operating tests be performed prior to releasing the tong assembly to a operational environment: Connect the tong to a hydraulic power source in a controlled environment. Ensure the power unit’s operating parameters are within the specifications as identified on Pg.
  • Page 46 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.

  • Page 47: Illustration 2.I.1: Master Lifting Link

    2: C & o KT14-75K HYDRAULIC POWER TONG ommissioning peration 2.H.6 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.

  • Page 48: Illustration 2.I.2: Backing Pin Set To "Make-Up" Position

    (see Section 2.G.1). The snub line prevents the tong body from spinning in the opposite direction of the cage plate when torque begins to build in the joint. McCoy Global recommends using two snub lines when running the equipment to eliminate uncontrolled movement in either rota- tional direction.

  • Page 88 3: M KT14-75K HYDRAULIC POWER TONG aintenance Perform a complete greasing of the tong - refer to Maintenance section of the technical manual Ensure main supply and return connections to the tong are fully made up. Re-connect the remainder of the hydraulic lines, and, if applicable, the electrical line to the turns counter.
  • Page 89 Prepare areas to be painted to ensure they are free of grease, dirt, or solvent. Touch up using a solvent-based acrylic paint - “McCoy Grey” is paint color number RAL7015, “McCoy Yellow” (hazard areas) is RAL1007, and McCoy Green is RAL6029 (contact McCoy sales for paint number for custom paint applications).
  • Page 90 Extend all hydraulic cylinders, and inspect cylinder rods for signs of mechanical damage, flaking, or rust. McCoy recom- mends that damaged cylinders be replaced prior to storage.
  • Page 91 NEVER OPERATE YOUR EQUIPMENT WITH A BYPASSED OR MALFUNCTIONING SAFETY DOOR McCoy recommends that an anti-corrosive agent such as Tectyl® 506 be applied to all external unpainted surfaces (and chain slings) EXCEPT cylinder rods, jaw rollers, and rotary gear camming surfaces. Refer to manufacturer data sheets for proper application and safety information.
  • Page 92 Inspect all paint - locations in which the paint has been damaged must be repaired prior to storage. Prepare areas to be painted to ensure they are free of grease, dirt, or solvent. Touch up using a solvent-based acrylic paint - “McCoy Grey” is paint number RAL7015.
  • Page 93 Apply grease or heavy oil to all exposed cylinder rods. McCoy recommends that an anti-corrosive agent such as Tectyl ® 506 be applied to all external surfaces EXCEPT cylinder rods (including chain slings). Refer to manufacturer data sheets for proper application and safety information.

    Place the equipment on a sturdy pallet constructed of 4” x 4” cross-members and 2” x 4” flooring. McCoy recommends placing a 2” x 6” board across the width of the tong under the legs (see Illustration 3.M.1). Ensure the pallet is large enough to accom- modate the wooden crate containing the tong accessories.

    1 mil polyethylene wrap. Use the wrap to conform the plastic cover to the general shape of the equipment, but do not wrap so tight that sharp edges on the equipment perforate the cover. McCoy recommends enclosing the equipment in a sturdy shipping crate which is securely fastened to the pallet. 3.41...
  • Page 96 These procedures are essential for ensuring proper equipment preparation and operation. The following procedures also assume that the decommissioning and storage procedures recommended by McCoy Global have been strictly observed. Remove all protective plastic wrapping. If there are desiccant packs with the assembly, they may be disposed of with the regular garbage.
  • Page 97 3: M KT14-75K HYDRAULIC POWER TONG aintenance Perform a full functional test of the equipment including, if applicable, backup components and float frame components. Report and correct any hydraulic leaks from the hydraulic valve bank, or from any hydraulic cylinders that are used. If using a frame-mounted tong and backup system, raise the tong off the beams that it is resting upon.

Functional Group: Model: Products : Cartridges : Reducing : 3 Port : Direct Acting Reducer PRJR-LAN Product Description Direct-acting, pressure reducing valves reduce a high primary pressure at the inlet (port 2) to a constant reduced pressure at port 1.
  • Page 191 7: OEM D KT14-75K HYDRAULIC POWER TONG OcuMEntatiOn Full reverse flow from reduced pressure (port 1) to Leakage specified in Technical Data is out of port 3 inlet (port 2) may cause the main spool to close. If with a supply pressure of 2000 psi (140 bar) and the reverse free flow is required in the circuit, consider valve set at mid range.
