Titan T Serie Manual Del Operador página 9

Reaction Arm
• Every Titan T‐Series Hydraulic Torque tool is equipped with a universal reaction arm. This component is used to counteract turning forces as the unit ope-
rates. The reaction arm can rotate 360° in 6° increments and should extend in the same direction as the square drive, see Figure 7.
Typical Reaction Configuration and Adjustability
WARNING !
• NEVER CUT, WELD OR MODIFY REACTION ARMS!!!!!
• THIS CAN CAUSE SERIOUS INJURY OR DEATH TO THE OPERATOR AND DAMAGE TO THE TOOL OR APPLICATION.
• CONTACT TITAN IF A CUSTOM REACTION ARM IS REQUIRED.
To attach the reaction arm to the tool:
1. Determine the best position for the reaction arm on the application
2. Align the splines on the reaction arm to the splines on the tools
3. Slide the reaction arm onto the tool till a "click" is heard. Pull reaction arm to confirm it is secure.
4. To remove, push the reaction arm lever (gold lever shown in Figure 7) and slide the reaction arm off the tool.
Determining the Pump Pressure
The torque of your Titan LP‐Tool is controlled via the pressure of the pump. Every Titan tool comes with a pressure to torque calibration chart that will help you determine
the pump pressure settings for your torque requirements.
• Refer to the torque requirements of the plant or equipment manufacturer before beginning the job.
1. Locate the torque chart (Figure 10) for your tool serial number and find the closest torque to your requirements. For this example, we will use a T3 to torque to 1,100
ft‐lbs, this procedure applies to the LP‐Tool as well.
2. For this example, the closest torque is 1089 ft‐lbs (within +/‐ 3% of the tools accuracy) and the corresponding pressure is 3400 psi.
3. Set the pump to 3400 psi following the instructions in Section "Reaction"..
Adjusting the Pump Pressure
• Make these adjustments BEFORE putting torque wrench on nut or bolt head.
A) See torque wrench chart to have the amount of pressure required to produce desired torque.
B) Press and hold the white button to advance the piston.
C) While holding the button, slowly turn the pressure valve (clockwise) to increase pressure on the gauge.
D) Stop when the required pressure appears on the gauge and release the button.
E) Repeat A to see the pressure on the gauge.
F) If the pressure on the gauge is not correct, repeat step B to D
• Once the desired pressure has been reached tighten the lock nut on the pressure control valve.
• You can put the tool on the nut and run the pump.
Setup to Tighten Fasteners
1. Once you have set your target pressure, cycle the tool several times without load to ensure the system is operating properly and any air is out of the lines.
2. Place the proper sized impact grade socket on the square drive. Insert the retaining pin into the hole in the socket and square drive and secure with the retaining O‐ring.
3. Place the tool with socket on the nut and double check that the retaining ring is secure.
4. Place the reaction arm boot (Figure 12) against a strong stationary object (i.e.) an adjacent nut, flange or equipment housing.
NEVER HOLD THE TOOL DURING OPERATION
5. Be sure all body parts are out of harm's way.
5. Make sure all hoses and electric cords are clear of obstructions and the tool.
6. Apply momentary pressure to ensure that the tool is properly placed and does not "ride up" or move on the application.
Operation
1. Depress the white button on the remote control. The tool will spin slightly about the ratchet until the link contacts the reaction point.
2. Continue to hold down the advance button as the ratchet turns. You will hear several audible "clicks" of the reaction pawl as the ratchet turns. When these "clicks" stop,
the piston is at the end of the stroke and pressure will increase rapidly.
Note: The reading of the preset pressure after the piston is extended DOES NOT indicate the set torque is applied to the bolt. This only indicates that the piston is fully extended
and cannot turn the socket further.
3. Continuing to hold down the advance button will result in a rapid pressure increase.
4. Repeat steps 1‐3 until the tool stalls.
5. To verify the set torque is reached, release the advance button and allow the piston to retract. Depress the advance button again, if the tool stalls and the pump
pressure increases to the set pressure, the desired torque has been reached.
Note: Occasionally the tool will lock on the application and become difficult to remove. This usually happens when applying torque to long fasteners. To release the tool from the
fastener:
1. Depress the advance button on the control pendant.
2. Flip reaction pawl lever toward reaction arm and hold in position.
Note: If the reaction lever does not move, increasing the pump pressure slightly may help.
3. Release the advance button and allow the piston to retract. The tool should be free and it can be removed from the application
Removing Fasteners
To remove fasteners, follow these steps:
1. Change the drive to the direction necessary to loosen the fasteners, refer to Figures 5 & 6.
2. For right‐hand threads, square should rotate counter‐clockwise.
3. For left hand threads, square drive should rotate clockwise.
4. Press and hold the advance button. The ratchet should begin to turn.
5. Cycle the tool until the fastener can be removed by hand.
More torque is required to remove a fastener than to tighten it. If the tool was near maximum capacity during fastening, a larger tool may be required to remove the fastener.
5. TOOL CARE AND MAINTENANCE
1. Clean all dirt and grit from the link
If tool is used in an underwater situation, especially sub‐sea, remove all water. Dry and grease tool before storage.
2. Inspect the square drive, reaction arm, and housing for cracks and other signs of wear. If one is present, discontinue use and contact Titan for a replacement part.
3. Store tool in a clean, dry area.
Note: Storage cases are available from Titan at an additional cost.
• Following these simple procedures can extend the service life of your tool.
• RE‐calibrate your tool periodically. Over time, internal components wear and can bring the tool out of calibration. Titan recommends a 6‐12 month calibration
cycle. Your work may require a different calibration cycle, check with your manager for this cycle.
• Periodically clean and lubricate internal parts in the tool with Dow Corning GN Metal paste.
