Warning
XQ140/30 tubing power tong is a kind of high mechanical torque wrench. To ensure safety,
operator should follow the safety information described in this manual.
1. Safety Information
1.1 Hanging of power tong
Use a wire rope not less than 1/2in (dia.) as hanging and fixing rope.
Warning: Prior to hang the tong, check wire rope, pulley, shackle and other attachments if worn or
damaged, if well maintained, and lock device if effective. It will cause serious damage on man and
rig equipment in the process of handing the power tong if failure of hanging happens.
1.2 Fixing of safety rope
Use a wire rope not less than 5/8in(dia.) to connect the tong tail, as safety rope.
Warning: During working, the tong tail part is easy to impact. It is necessary to attach a safety rope
against sliding of backup tong. Bearing connecting, check the rope and its attachments such as
shackles for worn and damage, and check lock device if effective. Failure of wire rope in the
process of handling the power tong will cause severe personal injury and equipment damage.
1.3 Connecting of hydraulic hoses
Warning: Ensure joints completely sealed. Improper maintenance and operation may cause leaking
of hoses, which will cause environmental pollution. Operators should be familiar with the operation
procedures and
1.4 Operating of power tong
Warning: Avoid any part of human body or clothes near the rotating area of the power tong.
Operator and other people should keep away from tong tail power direction to prevent personal
injury and equipment damage.
Warning: Do remember to shut off power unit when replacing jaws of the power tong.
Warning: Never allow to operate the tong when the tong door is open.
Warning: Do not put the tong operation handle at the same location under any situation, or the tong
will fail to control.
1.5 Others
Warning: Do not adjust, maintain, dismantle or lubricate the power tong when the power unit is n.
Warning: Hydraulic hose and seal rings for replacing should be proof pressure tested under 21MPa
(3000psi).
Warning: Remember to use genuine parts manufactured by Goldenman Company.
2. Overview
As one kind of open throat power tong used for making up and breaking out pips in the well

Goldenman Petroleum Equipment Co., Ltd
workover operation in oil field, XQ140/30 tubing power tong is applicable to tubing, small drill
pipe or small casing within the scope of 60-140mm. It is applicable to both land and offshore
oilfields. Featured by simple structure, convenient operation, broad range of application and large

4. Installation
4.1 Suspension
Connect spring hanger (or lifting hydraulic cylinder) with hanging rod of master tong and hoist the
tubing power tong on the derrick of workover rig. The suspension point shall be more than 15m
from the wellhead. The center of tong head should be about 0.7m far away from wellhead under
free suspension state. The suspension height is proper if the back-up tong just can grip tool joint or
the coupling of tubing or casing. Refer to Fig.1.
Fig.1 Installation over wellhead Fig.2 Balance Adjustment
4.2 Leveling

Goldenman Petroleum Equipment Co., Ltd
Adjust the adjusting screw on the hanger rod to make the tubing power tong always horizontal.
Clamping will be a failure if the tubing power tong is not kept horizontal. Refer to Fig.2.
4.3 Installation of sensor
Refer to Fig. 3 for installation of sensor according to working status of makeup or breakout.
Fig.3 Location of the sensor Fig.4 Local view of Tong foots
4.4 Installation of jaw plate
Select proper jaws based on the pipe to handle. During the installation, always make sure the
opening of brake disc and notched gear is consistent. In this way, the pulling rod is at the back side,
which will facilitate the installation of jaws. Pay attention to the right and left direction during the
installation process, refer to Fig.5. Add lubricating grease to jaw pins and fix them with cotter pins.
Refer to Table 1 for jaw specification details.
4.5 Connection of hydraulic pipeline
Prior to starting the hydraulic power station, connect the high pressure hose and oil return hose to
the power tong and hydraulic power unit.
4.6 Additional information
It is necessary to remove front tong feet before operating the tong, and loosen the nuts below the
connection. Refer to Fig.4.

5. Setting up
5.1 Torque
Torque control on tubing power tong XQ140/30 includes manual control and automatic control.
Manual control is to set the red pointer on torque meter to required value. Then operate multi-way
valve handle to take torque value to this point and then back to middle position. Tong head stops
working. Automatic control is to connect tension sensor and solenoid valve of power unit with the
computer. Preset required torque value in the computer. It tong torque is up to required value, the
computer it will control the power unit to unload. So the tong head stops working.
5.2 Pressure of backup tong
5.2.1 Hydraulic system of backup tong includes one pressure reducing valve and one increasing
valve. Firstly reduce pressure to 10MPa, the increase pressure via the increasing valve. Refer to
Fig.7 for pressure reducing valve. Loosen lock nut and adjust the screw, you can control pressure of
backup tong.
5.2.2 Operate the multi-way valve handle for backup tong, from the pressure gauge of backup tong
you can see the cylinder pressure value is on the increase. Release the valve handle, pressure will
not change anymore and remain unchanged.

Goldenman Petroleum Equipment Co.,Ltd
5.2.3 Pressure setup of backup tong depends on pipe size and thickness, and actual torque needs for
makeup and breakout, ranging from 2 MPa to 40 MPa.
6. Operation Procedure
6.1 Put two-position tee valve to the side of suspension cylinder, then push left handle of
combination valve forward to raise the tong up and align against tubing coupling. Refer to Fig.6. If
need to adjust a little downwards, operate the manual valve on the combination valve, refer to
Fig.12. Warning: Never to operate the combination valve handle.
6.2 Control of combination Valve

Goldenman Petroleum Equipment Co.,Ltd
The left handle of combination valve of this power tong can control the positive and negative
rotation of tong head, while the right handle can control the cylinder of back-up tong to clamp or
release, and the suspension cylinder to lift.
6.3 Adjust the nut at one end of brake band to make brake band tighten brake disc, refer to Fig.10.
6.4 Turn shifting lever assembly to its required position, makeup or breakout. Refer to Fig.9.
Fig. 9 Shifting Lever Position of Main Tong for Makeup/Breakout
Fig.10 Adjustment of Brake Band
6.5 Operate the right and left handles of combination valve, to open the openings of the main tong
head and back-up tong respectively.
6.6 Push forward the power tong and entangle pipe column with tong head. The pipe column should
be in the middle of jaws.
6.7 Close the main tong door.

Goldenman Petroleum Equipment Co.,Ltd
6.8 Operate right handle of the combination valve, to make back-up tong clamp pipe column. Refer
to Fig.8 for its gripping torque.
6.9 Operate left handle of the combination valve to clamp/release the pipe column, and then rotate
tong head reversely to move jaws apart from pipe.
6.10 Open the main tong door, and move power tong from pipe.
6.11 Shut down the power unit.
7. Maintenance and Lubrication
7.1 Prior to job each day, check if all tightening screws are loose and fasten them if necessary.
7.2 Prior to job each day, add sufficient lubricating greases to all transmission parts, refer to Fig.11.
7.3 Check the tong after each time use. Remove water or sludge timely (if any).
7.4 Replace brake band when its thickness is below 8mm (original 10mm) after worn.
7.5 Clean the tong with diesel oil after completion for one well and coat grease on all rotation parts
after cleaning.
7.6 Never allow to clean the tong with steam to avoid damaging bearings due to oil-lacking and
water invasion.
7.7 Hydraulic oil temp shall be no over 65℃since being overheat will make the sealing of
hydraulic system invalid.
7.8 Always make hydraulic oil clean and ensure the oil filter can work normally. Change oil
immediately once it becomes dirty.
7.9 Selection of hydraulic oil:
7.9.1 YC-N46 low-freezing hydraulic oil, which is applicable to -20℃~+50℃;
7.9.2 YB-N46 anti-wearing hydraulic oil, which is applicable to -10℃~+50℃;
7.9.3 YA-N46common hydraulic oil, which is applicable to 0℃~+50℃。
