Page 3 If you have any questions on our manual, please contact Goldenman Petroleum Equipment Co., Ltd. TQ508-70Y hydraulic casing tong can work normally not only in the warm weather, but also under extreme cold climate. Its structure is simple and reliable and can be dismantled without the use of special tools.
Page 4 12.Jaws available for casing sizes(normally): 9-5/8”, 13-3/8”, 16”, 18-5/8” and 20” III. Assembly 1. Jaw installation (see illustration) To install the jaws, remove the two jaw pivot bolts. Plate one jaw at a time between the upper and lower cage plates. Align the hole in the jaw with the matching hole in the cage plates, and insert the jaw pivot bolts.
Page 5 page): 3. Leveling tongs To insure even gripping action of the dies, and smooth running of the rotary gear, it is essential that the tong be hung level. This can be accomplished by making a few simple adjustments once the tong is hung. To level the tong, turn the turnbuckles on the bridle assembly to the desired tong alignment with the pipe.
Page 6 4. Back-up line The use of a 5/8’ or larger wire rope is recommended for the tong back-up line. It should be securely connected to the load cell at the rear of the tong and tied off to a suitable anchor. To assure accurate operation of the load cell and torque gauge, the back-up line should be connected at a 90 degree angle with the tong, and in the same horizontal plane.
Page 7 multi-way reverse valve and hydraulic check valve are to control their action. Lift cylinder is installed on the top of the spring hanger assembly. Cylinder end connects with the shackle of spring hanger assembly through connection fork. One end of the hose is to attach oil inlet on the cylinder and the other end is to attach the quick change joint on the multi-way reverse valve.
Page 8 Start up the power unit by following operation manual of power unit. Prior to starting engine, loosen relief valve and make an inspection to assure proper lube oil level in the pump and engine, and hydraulic oil level in the hydraulic tank. Check all pressure and return line hose connections to make sure they are securely installed.
Page 9 push the valve handle forward, and for reverse rotation, pull the valve handle in the opposite direction. Speed in either direction is proportional to the distance that the valve handle is moved form the center position, as the valve core of multi-reverse valve has the throttle function.
Page 10 Proper location of backing pin for make-up 5.7 When casing threads begin to make up, push the valve handle to full forward until the tong begins to stall. 5.8 Release the multi-reverse valve handle and shift to low gear. 5.9 Engage throttle and make-up casing to desired torque. 5.10 Pull the multi-reverse valve handle backward slightly to reverse tong to disengage jaws and rotate until rotary gear aligns with the door opening.
Page 11 6.5 Shift transmission into high gear. 6.6 Pull the multi-reverse valve handle to full position. 6.7 It is recommended to break out in low gear until the joint is completely unscrewed. 6.8 Push the multi-reverse valve handle forward slightly to reverse tong to disengage jaws and rotate until rotary gear aligns with the door opening.
Page 12 V. Maintenance It is suggested that a regular maintenance program be established t assure dependable operation of the hydraulic tong. Clean, lubricate and adjust the tong in accordance with the following recommendations to enhance the life expectancy of the tong and assure safety to operating personnel. 1.Cleaning The tong should be thoroughly cleaned with a good petroleum base cleaning agent after each job, prior to storage.
Page 13 2.5 Big and small rollers between top and bottom face of the tong. Coat the surface of the rollers with a thin layer of grease. 2.6 Shifting shaft Apply grease to the shifting shaft at the bushings through the grease fitting (7). 2.7 Door latch shaft Grease should be applied to the shaft through the grease fitting (1) at the door latch shaft.
Page 14 gear alignment, reduce possibility of transmission impact and assures safety to operating personnel. 2.Brake band adjustment: (see illustration) As the tong is used, it becomes necessary at times to adjust the brake bands to provide a smoother and more efficient jaw cam action. When brake band is loose, cage plate will turn along with rotary gear , the jaw will not cam properly and therefore, will not bite on the pipe.
Page 15 After each job, check the backing pin for wear or cracks. If stress cracks or excessive wear exists, the pin should be replaced. 5.Overhaul procedure If the need arise to overhaul the tong, do as follows: Note: All maintenance and overhaul can be accomplished from the top. Therefore, the bottom plate of the tong should never be removed.
Page 16 5.5.10 Remove the 14 top roller shaft nuts. 5.5.11 Remove the 3/8” bolts around the perimeter of the tong which secure the top plate. 5.5.12 After all the above steps, the top tong plate can be lift off providing access to the inside of the gear case.
Page 17 6.2.5 Excessively worn or damaged pump or tong. Solution: Replace worn parts by following manufacturer’s recommendations. 6.2.6 Viscosity of oil too high. Solution: Change oil. 6.2.7 Restriction in line between power unit and tong. Solution: Check self seal couplings to insure they are properly engaged. 6.2.8 Relief valve not functioning.
Page 18 6.4.3 Jaw roller broken or worn. Solution: Replace roller. 6.5 Failure of tong 6.5.1Pressure too low. Solution: Reset relief valve. 6.5.2 Multi-reverse valve damaged. Solution: Repair or change the valve. 6.5.3 Clutch damaged. Solution: Repair or replace damaged parts. 6.6 General comments The following factors contribute highly to inefficient hydraulic operation.
