3. 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.
3.1 Transmission System
Hydraulic power tong has four shifts to reduce speed, as shown in figure 1.

3.2.1 Clamping Mechanism (Fig.3-2, Fig.3-3)
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 loses the pipe string.
3.2.2 Braking Mechanism (Fig.3-2)
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.

3.2.3 Reset Mechanism (Fig.3-2)
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.

3.2. 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.

4.6Running-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. (see Fig.28)
□Open the safety door, deliver tong to the well head, and watch whether the space
between master tongs and backup tong suitable or not. Adjust the space between
them if not suitable. The adjusting procedure is shown at 5.5
□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.
