I. Introduction
The manual includes instructions for installation, operation and maintenance, as
well as problem diagnosis information. It also includes drawings and parts list which
serve as a reference for operation and maintenance. Please read the manual and
observe maintenance instructions. If you have any questions on our manual, please
contact Goldenman Petroleum Equipment Co., Ltd.
TQ508-70Y hydraulic casing tong can work normally not only in the warm weather,
but also under extreme cold climate. Its structure is simple and reliable and can be
dismantled without the use of special tools. Only simple maintenance can elongate
its service life. All supporting parts are of high-performance alloy steel and are
strong due to appropriate heat treatment and strict machining. Important parts like
motor are imported to secure its reliable and safe running.

III. Assembly
1. Jaw installation (see illustration)
To install the jaws, remove the two jaw pivot bolts. Plate one jaw at a time between
the upper and lower cage plates. Align the hole in the jaw with the matching hole in
the cage plates, and insert the jaw pivot bolts.
2. Tong rig-up
The tong should be suspended by 5/8” diameter (minimum) wire rope and from a
location in the derrick high enough to assure easy handling and maneuvering of the
tong. The hang line should be placed in a position in a position as near the center of
the rotary as possible without interfering with the movement of the hoisting
equipment.
This line may eight be extended over a pulley (over 3ton) and balanced by a
counterweight equal to the weight of the tong or simply tied off in the derrick to form
a dead line. In cases where the dead line arrangement is used, it is necessary to
use the spring hanger assembly, which allows the tong to compensate for the
downward movement of the casing as the thread made-up. (See illustration-next

page):
3. Leveling tongs
To insure even gripping action of the dies, and smooth running of the rotary gear, it
is essential that the tong be hung level. This can be accomplished by making a few
simple adjustments once the tong is hung. To level the tong, turn the turnbuckles on
the bridle assembly to the desired tong alignment with the pipe. (See illustration.)

4. Back-up line
The use of a 5/8’ or larger wire rope is recommended for the tong back-up line. It
should be securely connected to the load cell at the rear of the tong and tied off to a
suitable anchor. To assure accurate operation of the load cell and torque gauge, the
back-up line should be connected at a 90 degree angle with the tong, and in the
same horizontal plane. (See illustration).
5. Lift cylinder connection
Hydraulic lift cylinder is available to favor the upward and downward movement of
the tong. The lift cylinder and power tong share the same hydraulic source. And

multi-way reverse valve and hydraulic check valve are to control their action.
Lift cylinder is installed on the top of the spring hanger assembly. Cylinder end
connects with the shackle of spring hanger assembly through connection fork. One
end of the hose is to attach oil inlet on the cylinder and the other end is to attach the
quick change joint on the multi-way reverse valve. (See illustration).
6.Hydraulic hoses
When the power unit is not running, the hydraulic hoses may be installed to the tong.
Both 1”high-pressure hose and 1-1/4”return hose are equipped with self-seal type
couplings, and care should be taken to insure complete engagement to prevent
partial closure of the check valve in the coupling.
IV. Tong Operation
1.Start up procedure
Note: Be sure the doors are closed and securely latched before power unit is
started to insure safety for operation personnel.

Start up the power unit by following operation manual of power unit. Prior to starting
engine, loosen relief valve and make an inspection to assure proper lube oil level in
the pump and engine, and hydraulic oil level in the hydraulic tank. Check all
pressure and return line hose connections to make sure they are securely installed.
Note: Failure to have these hose connections tight will stop or restrict oil flow and
result in high pressure on the power unit hydraulic system.
Start the power unit engine and make the hydraulic oil circulate for approximately
10 minutes, adjust relief valve to set the circulating pressure up to 2Mpa. Place the
tong gear shifter in low gear and control multi-reverse valve to rotate the tong slowly
in forward and reverse directions. Once this has been done and the proper size
jaws have been installed, the tong is then ready to run pipe.
2.Hydraulic control system
Multi-reverse valve controls the action of motor and lift cylinder. The hydraulic circuit
is parallel connection. Motor and lift cylinder can act individually or simultaneously.
(See illustration.)
3.Direction and speed control
Multi-reverse valve controls direction and speed of rotation. For clockwise rotation,

push the valve handle forward, and for reverse rotation, pull the valve handle in the
opposite direction. Speed in either direction is proportional to the distance that the
valve handle is moved form the center position, as the valve core of multi-reverse
valve has the throttle function.
4.High and low gear
The gearbox provides for high and low gear operation. For low gear the shifting
handle is simply move upward from neutral position, and for high gear, the shifting
handle is moved from down from neutral position. (see illustration).
Warning: Stop the tong when shifting high or low gear.

Note: Do stop the tong when shift high and low gear.
5.Make up of casing
5.1 Align door opening with gear opening.
5.2 Place tong around casing.
5.3 Close the safety door completely.
5.4 Place the backing pin in the “make-up” hole. (See illustration)
5.5 Shift transmission into high gear.
5.6 Gently push the multi-reverse valve handle forward until casing threads begin to
make up.

5.7 When casing threads begin to make up, push the valve handle to full forward
until the tong begins to stall.
5.8 Release the multi-reverse valve handle and shift to low gear.
5.9 Engage throttle and make-up casing to desired torque.
5.10 Pull the multi-reverse valve handle backward slightly to reverse tong to
disengage jaws and rotate until rotary gear aligns with the door opening.
5.11 Open the door and remove the tong from pipe.
6. Break out of casing
6.1 Align door opening with gear opening.
6.2 Place tong around casing.
6.3 Close the safety door completely.
6.4 Place the backing pin in the “break-out” hole. (see illustration)
