It greatly reduces the labor of worker, enhances connection quality of thread and diminished accidents in inappropriate casing operation.Features:l. Opening type, convenient and prompt to enter and slide off the working position, with an integral tong head of great strength and rigidity.2. Double swing head jaws, very convenient to assemble and disassemble, with the best design for tangent-diameter ratio, ensuring the reliability of gripping and easy cam- backslide.3. Band brake of great moment, easy to operate and convenient to maintain and replace.4. Notched gear new type sporting structure, greatly improving the strength and rigidity.5. Wholly hydraulic mode. High torque motor of swing cylinder type will supply effective power. The power tong takes mechanical gear changing and its structure is simple and reliable.6. The shell is thickened with Mn. The jaws are cast with precise technology, artistic and strong.7. The hydraulic torque gauge as well as the joint for a round-torque gauge makes it possible for computers to manage the process.SECTION ⅡPERFORMANCE PARAMETERSⅠ. Technical parameters1.

Fix the single pulley (3.3 US ton) under beam of the crown block.2. Get a wire rope (at least 1/2") through the pulley, with one end fixed on the base beam. The height of the tong should be at the same level as the average height of joint during making up and breaking out casing.ⅡLevel the tongThe tongs must be leveled when hung up, or the dies will be sliding to grip.Front and back level - adjust the two screws at the joint where the tong is connected with their hanger.Crosswise level - turn the screw rod at the top of the hanger.ⅢConnect the rear wireThe wire, at least 5/8", is connected with the ring of the torque cylinder at the end of the tongs, the other end fixed on the derrick or the drilling platform.NOTE：When the wire rope is tightened, it should be almost at the same level of the tongs, and be at an angle of 90°from the tong medium line.ⅣFill the torque oil cylinderWhen the piston rod is pulled out 30mm long, oil must be filled. Use the hand-oiling pump equipped with the tong to oil the torque cylinder until the hand of torque gauge acts.ⅤConnect the pipesHigh pressure oil hose – NPT1 or M30*l.5 joint connects with high-pressure hose from the power unit.Low-pressure return hose – NPT11/4 or M42*2 joint connects with low-pressure hose from the power unit.Drain hose – M18*l.5 joint connects with the small return line from the power unit. SECTION ⅣOPERATIONⅠRequirements1. Know the tong structure and the properties.2.Know the use of the hydraulic hand-reversing valve and of the speed-changing handle.3.Know the operation sequence and safety requirements.4. Know the functions of the meters.ⅡPreparation for the operation .1. Install the jaws that go with the casing pipe. Note that the two jaws should be installed correctly.2. Put the handles of the hydraulic hand-reversing valve and the speed-changing handle at neutral position.3. Start the hydraulic power unit.4. Push or pull the handle of the hydraulic hand-reversing valve, and you will hear the hydraulic motor while the tong head notched gear remains still.5. Set the handle of the speed-changing handle at high or low gear. Push or pull the handle of the hydraulic hand reversing valve, and the notched gear turns smoothly in forward and reverse direction.Attention: Do stop the tong when change gear.Ⅲ Working process1. Align the gear’s notch with the jaw rack’s notch.2. Set the backing pin into “make up” or “break out” hole, and adjust the brake band.3. Align the gear notch with the case notch.4. Draw the safety door open, push the tongs to working position and close the door. *Making upa. High gear operation: Set the handle of speed-changing handle at high speed position and the handle of hydraulic reversing valve at “make up” position. Jaws clamp the casing tightly and drive the casing rotate in “make up” direction. At the same time watch the torque gauge. If the reading fails to reach the needed value, change to low gear.b. Low gear operation: Stop the motor and put the speed-changing handle at low gear, and operate the direction-reversing valve, the casing pipe will turn slowly. Watch the torque gauge at the same time. When the reading reaches the needed value, put the handle of hydraulic reverse valve at mid position.c. Set the handle of hydraulic reversing valve at “break out” position, then choose high or low gear according to the proficiency of operator and the position of notched gear. Jaws loose. The rotary gear turns in “break out” position. When it aligns with the case notch, set the handle of hydraulic reverse valve at mid position.d. Open the safety door and draw back the tong. That is one make-up.* Breaking outa. Low gear operation: set the speed-changing handle at low gear position, the handle of the hydraulic reversing valve at “break out” position, and the casing turns slowly in the direction to break out.b. High gear operation: When the casing turns to a certain angle it can turn at high gear, stop the tong and set the speed-changing handle at high gear position, and then the casing turns at high speed in the direction to break out.c. When the screw threads are apart, the operator may choose a proper position for the speed-changing handle according to his own proficiency and the gear notch position. Push the handle of the hydraulic reversing valve to “make up” position. When the gear notch and the case notch are aligned, set the handle of the hydraulic reversing valve in the middle position.d. Open the safety door, and slide the tong off the casing. A break-out is done.ⅣSafe rules of operation1. Do stop the power station when remove the jaws, in case of accidents.2. When set the jaws, notice the difference between the left and right jaws.3. Do not turn the notched gear until the safety door is closed, so as to avoid injury.4. Check regularly the suspension rope and the rear rope to keep safe.5. The tong should be stopped when change speed.SECTION ⅤMAINTENANCEⅠSet up system of job responsibility.ⅡGrease fittings and slide faces before every use.ⅢRun through all the procedures in item II section IV before use.ⅣThorough cleaning is necessary after use. Grease the head of the tong against rusting.ⅤKeep the tong at a dry and clean place far from the drilling platform, the exposed part of the head should be greased.ⅥWhen moving the tong, be sure to cover each inlet and outlet to prevent dust from entering the pipes.ⅦThe tong needs complete repair and maintenance after the tong is already used for about ten wells.SECTION ⅥLUBRICATION1. Inject No.3 Calcium base grease into each fitting by using grease gun. Once a shift. Turn the tong head by means of a pinch bar. Use a brush to grease notched gear, rollers with No.3 calcium base grease. Once a shift. Remove the cap for inspection hole (Fig.5, No.6), and grease drive gear. Once a shift.Fitting distribution is as follows (Refer to Fig. 5)No.1,82,10345,791112Location SafetydoorUpper andlower jaw racksCentralizingrollerDrivegearGear shiftdeviceBigrollerSpeed-measuring gearLowerbearing capQty. 437105322122.Remove motor and gearbox cover, wash clean gearbox, and inject molybdenum disulfide lithium base grease into the box. Once every three wells.Take off upper panel, clean drive gear and housing. Inject No.3 calcium base grease. Once every three wells.3.When reassemble the tong after repair, bearings and gears in the gearbox should be greased with molybdenum disulfide lithium base grease.
