3.1 Transmission SystemHydraulic power tong has four shifts to reduce speed, as shown in figure 1.Low Gear Engagement: Z2, Z1, Z3, Z5, Z6, Z7, Z11, Z12, Z13Second Low Gear Engagement: Z2, Z1, Z3, Z5, Z10, Z11, Z12, Z13Second High Gear Engagement: Z2, Z4, Z6, Z7, Z11, Z12, Z13High Gear Engagement: Z2, Z4, Z8, Z9, Z10, Z11, Z12, Z13

3.2 Clamping MechanismThe 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 frameassembly is fixed in the inner side of the open gear. The spline on the board matches the spline on theconnection 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 curvedsurface of the ramp, moving jaw plate assembly towards the center, thus the preliminary clamping isachieved.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 thepipe string. The backup tong clamping mechanism is the same as that of the master tong. The hydraulic oildrives rack plunger to make reciprocating movement and also drives the duplex gear and the jaw plateframe to turn inside the main body of the backup tong, which drives the roller to climb, finally clips orlooses the pipe string.

3.4 Hydraulic OilThe hydraulic oil used for power tong must be effectively filtrated to prevent sand, iron scraps entering toguarantee the efficient oil usage. Oil filtration accuracy mustn’t be lower than 0.025mm (10min).Recommended hydraulic oil is as follows:(1)YC-N46 low temperature solidification hydraulic oil, the appropriate environmental temperature is –20 ℃～+40 ℃;(2)YB-N46 abrasion resistant hydraulic oil, the appropriate environmental temperature is -10 ℃～+40 ℃ ;(3)YA-N46 hydraulic oil, the appropriate environmental temperature is 0 ℃～+40 ℃ .

4.1Check Before Installation●Check power tong damaged or not during transportation. If damaged, itshould be repaired.●Check the fastening parts loose or not, tighten any loose parts.●Check jaw plate, die seats and dies complete or not. (Fig.5.1)

4.2LiftingLifting operation at the drilling rig or work-over rig is shown as Fig.12.●Connect hydraulic bucket to the suspension bar of master tong by bolts.●Install a pulley on the mast, which can bear load of 4400bf or more.●Lift hydraulic power tong by a soft steel wire of 1/2″ or bigger, put thiswire through the pulley on the mast, one end connecting hydraulic bucketand the other end fixed at the mast. Make dies of backup tong directlyface the pipe string coupling or the drilling pipe tool joint(see detailedoperation at 5.2) .

●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.

4.4 Leveling(Fig.5)●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 thesuspension bar. Adjusting bolt●Check whether the backup tong parallel to the mastertong or not, if not, adjust them following the procedure of Fig.55.6.

●Power tong leveling is very important, if not level, the tong head clamping will fail to work. ●Four screws should be adjusted in coordination.

4.5 Tie Back Guy (See Fig.6)●Back guy should be tied well after leveling the tong. One endof the back guy should be tied to the pin axle at the tail of the Breaking-out directiontong; the other end should be tied to the mast. Left●The height of the end of back guy tied to the mast should besame as that of the tong. The back guy should be vertical withthe central line of tong body and also be pulled tightly.●Pay attention to the direction of the guy, the back guy shouldbe tied to the right hand side of the tong in the making-upoperation, but it should be on the left in the breaking-out Rightoperation when observed from the front of the tong head. Don’t Making-up directiontie it in the wrong direction(All above-mentioned are suitable forRight Hand thread, as for Left Hand thread, on the contrary.) Fig.6 Illustration of black guy

4.6 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 andbackup tong being synchronous or not. Adjust the direction of reset knob if they are not synchronous.●Open the safety door, deliver tong to the well head, watch whether the space between master tong andbackup 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 overflowvalve in the hydraulic system according to the table of the making-up torque value, shifts, torque andpressure parameter (See Fig.3) recommended by API.

Note: Being synchronous means both the master tong dies and the backup tong dies and the backup tongdies stretch out when operating the hand control valve in one direction. When operating hand control valvein the opposite direction, the jaw plate frame of the master tong and the opening gear face the opening ofmaster tong, the jaw plate frame of the backup tong and the main body of backup tong, too. The reason forbeing non-synchronous are:1.the wrong direction of the reset knob; 2.wrong connection of the hoses of thebackup tong is sure to slip, see 5.3.2 for the right connection method.

●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 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.

4.8 Treatment after useOperate 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 noteven.●Clean and maintain power tong as (6).
