4.0 TONG OPERATION
4.0.1 Operator Training
Many companies set qualification standards that must be met before equipment may be operated without
supervision. McCoy Global recommends operator training, which typically consists of operation of the equipment
under the supervision of a trained equipment operator until a satisfactory level of competence is achieved. Typical
operator training should include:
• Introduction to and general description of equipment
• Technical specifications and performance data
• Operating instructions
• Control systems and interlocks
• Operating hazards
• Checks and inspections
4.0.2 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 equipment and safety training.
This tong is provided without a safety door system. A safety door system must be provided and installed by the
end user. A safety door system is the primary device protecting the tong operator and nearby personnel from the
rotary gear when the tong door is opened. Confirm the correct operation of the safety door before every job. Never
disable the safety door device.
Ensure hydraulic power is deactivated and tong hydraulics are de-pressurized before disconnecting the main
hydraulic lines. McCoy recommends depressurizing the tong hydraulic system before connecting or disconnecting
quick-connect fittings.
The area surrounding the tong operating area must be clutter-free and free from tripping hazards, or protruding
objects that may snag hydraulic hoses on the tong, backup, lift cylinder, or torque measurement system. Operating
surface or drill floor must be kept free of slipping hazards like grease, oil, water, etc.
Adequate lighting of the work area is required. All warnings, labels, gauges, and signs must be clearly visible
The components of the tong commonly manipulated or requiring control input are painted green, and are safe for
continuous handling. Areas painted yellow are designated as hazardous areas, and contact with those areas must
be avoided during operation. Always wear all Personal Protective Equipment (PPE) specified by your company’s
HSE policy, and follow all of your company’s safety guidelines.
4.0.3 Remote Operation
This tong is designed with features to allow for remote operation of the tong. Shifting of gears, operation of
the backing pin, and opening/closing of the tong door are all controlled by hydraulic cylinders. The end user
is responsible for setting up any associated hydraulic plumbing and control consoles in order to operate the
equipment.
