1.Summary
Model XQ140/12A hydraulic power tong is a mouth opening power tong which can quickly make-up or
break-out pipe strings in well service. It is used in making-up or breaking-out tubing, small drilling pipe
and small casing with diameters from 23/8″-51/2″ (60mm to 140mm). Compared with the same type of tongs
by other tong makers, it features simple structure, convenient operation, reliable performance, long life,
broad application range and large torque. It is widely used in onshore or offshore oilfields. It can reduce
workload, improve work efficiency and the well service quality.
2.Structure Characteristics And Working Principle
Hydraulic power tong consists of two main parts----master tong and backup tong. The backup tong clips
coupling or joints, (It can also clip the pipe body by lengthening the front and back guide poles as required.)
and the master tong clips pipe string, turns clockwise or counter-clockwise, in this way, it completes
making-up or breaking-out operations.
2.1 Transmission System
Hydraulic power tong has four shifts to reduce speed, as shown in figure 1.
Low Gear Engagement: Z2, Z1, Z3, Z5, Z6, Z7, Z11, Z12, Z13
Second Low Gear Engagement: Z2, Z1, Z3, Z5, Z10, Z11, Z12, Z13

2.2.1 Clamping Mechanism (Fig.2, Fig.3)
The clamping mechanism adopts inner curved bilateral clamping mechanism. It consists of ramp plate,
roller, roller axle, jaw plate, die seats, tong dies and jaw plate frame assembly. The jaw plate frame
assembly is fixed in the inner side of the open gear. The spline on the board matches the spline on the
connection plate of braking mechanism. When the transmission system starts to drive the open gear to turn,
the jaw plate frame assembly doesn’t turn first at all under the braking force from the braking mechanism,
the curved ramp plate turns together with the open gear, the roller on the jaw plate climbs along the curved
surface of the ramp, moving jaw plate assembly towards the center, thus the preliminary clamping is
achieved.
As the torque increases and exceeds the braking moment, the open gear drives the spline connection plate,
braking disc, jaw plate frame assembly and the jaw plate in the braking mechanism to turn together with the
pipe string. The backup tong clamping mechanism is the same as that of the master tong. The hydraulic oil
drives rack plunger to make reciprocating movement and also drives the duplex gear and the jaw plate
frame to turn inside the main body of the backup tong, which drives the roller to climb, finally clips or
looses the pipe string.
2.2.2 Braking Mechanism (Fig.2)
Jaw plate frame assembly must be braked to drive roller and ramp to move in opposite directions (i.e.
climbing and resetting). The braking mechanism consists of braking plate, braking steel disc, spline
connection board, upper and lower friction disc, adjusting screw, spring and lock nut. It can change braking
moment by adjusting the compress force from the spring.

2.2.3 Reset Mechanism (Fig.3)
The initial working position of hydraulic power tong refers to the jaw plate frame and the open gear face
the opening of the shell body of the master tong, the jaw plate frame of the back-up tong faces the opening
of backup tong main body. The openings of master and backup tongs should be in alignment. After one
making-up and breaking-out operation ends, operate the hand control valve in the opposite direction to
return the hydraulic power tong to its initial working position, allowing the pipe string in or out through the
tong opening smoothly. During making-up and breaking-out, reset knobs on the master and backup tongs
should be in the same direction.
2.2.4 Centralizing Mechanism (Fig.2 and Fig.4)
The centralizing mechanism centralizes from up and down, inside and outside. It consists of roller
support frame, centralizing roller, centralizing roller axle and roller, which are respectively installed on the
shell body and the cover of the tong head. They match the open gear and the groove on the cover of the
open gear to guarantee the open gear turns along the original axle central line to avoid deflection and axial
running-out, thus the tong head is centralized.

face the pipe string coupling or the drilling pipe tool joint(see detailed operation at 5.2) .
4.3 Installing hydraulic pipeline
See 5.3.1,5.3.2
4.4 Installing the torque control system(operation parts,
see 5.4)
4.5 Leveling(Fig.13)
●Push hydraulic power tong to the clamping position.
●Check whether tong head level or not. If it is not level,
keep master tong level by adjusting four screws on the
suspension bar. Check whether the backup tong parallel to
the master tong or not, if not, adjust them following the procedure of 5.6. Fig.13
4.6 Tie Back Guy (See Fig.14)
Back guy should be tied well after leveling the tong. One end of
the back guy should be tied to the pin axle at the tail of the tong;
the other end should be tied to the mast.
The height of the end of back guy tied to the mast should be
same as that of the tong. The back guy should be vertical with
the central line of tong body and also be pulled tightly.
Pay attention to the direction of the guy, the back guy should be
tied to the right hand side of the tong in the making-up operation,
but it should be on the left in the breaking-out operation when
observed from the front of the tong head. Don’t tie it in the
wrong direction(All above-mentioned are suitable for Right
Hand thread, as for Left Hand thread, on the contrary.)
●The support point of the pulley must be installed 15 meters above the well head.
●Central line of the power tong head is located at 0.6m away from the vertical line of
the well head in free suspension state.
●Avoid breaking the hose due to twisting in use.
●The piston rod extends and faces downward when installing the bucket.
●When the backup tong directly faces the pipe string coupling or the drilling pipe joint,
the piston rod of the bucket should be located at half of the stroke.
●The suspension height of the hydraulic tong can be adjusted easily with the hydraulic
bucket.
●Power tong leveling is very important, if not level, the tong head clamping will fail to
work.
●Four screws should be adjusted in coordination.

4.7 Running-in Operation
●Supply hydraulic power tong with oil.
●Control the lifting bucket; adjust the height of power tong.
●Keep free-load running at low gear for 1 to 2 minutes.
●Keep free-load running at high gear for 1 to 2 minutes.
●Test tong head running in clockwise and counter-clockwise directions, watch whether master tong and
backup tong being synchronous or not. Adjust the direction of reset knob if they are not synchronous.
●The adjusting procedure is shown at 5.4.
●Open the safety door, deliver tong to the well head, watch whether the space between master tong and
backup tong suitable or not. Adjust the space between them if not suitable.
●Try to clamp the pipe string at high gear, adjust system oil supply pressure by adjusting the overflow
valve in the hydraulic system according to the table of the making-up torque value, shifts, torque and
pressure parameter (See Fig.6) recommended by API.
Note: Being synchronous means both the master tong dies and the backup tong dies and the backup tong
dies stretch out when operating the hand control valve in one direction. When operating hand control valve
in the opposite direction, the jaw plate frame of the master tong and the opening gear face the opening of
master tong, the jaw plate frame of the backup tong and the main body of backup tong, too. The reason for
being non-synchronous are:1.the wrong direction of the reset knob; 2.wrong connection of the hoses of the
backup tong is sure to slip, see 5.3.2 for the right connection method.
4.8 Making-up or breaking-up operation
See 5.7, 5.8 for recommended steps.
4.9 Treatment after use
Operate as the following procedures after the work is finished.
●Cut off power source.
●Remove the high-pressure hose.
●Protect oil inlet and outlet to prevent sand or iron scraps getting in.
●Check fastening parts, fasten the loose parts.
●Put down power tong, place it in an even place, otherwise the tong will be damaged if the place is not
even.
●Clean and maintain power tong as (6).
●Don’t disassemble hydraulic pipe at high pressure, otherwise, accidents may occur and
the equipment may be damaged.
●Don’t approach the running part of hydraulic power tong by your body or clothes.
●Only operators are allowed to approach hydraulic tong to avoid any trouble caused by
turning the operating lever.
●The hand control valve may be slightly operated to realize gear shifting at low gear to
avoid damaging the gear.
●The temperature of the hydraulic oil should not be over 65℃.Over heating can make
hydraulic system seal fail to work and slow down the running speed of tong.
●Proper treatment prolongs the life of power tong after use.
