10 Interesting Things About XLCT torque wrench

10 interesting things about XLCT are as following-

1.It provide torque from 329 Nm To 42005 Nm.

2.The most used limited clearance torque wrench in the world.


3.HYTORC's patented In-Line Reactor permits the use of drive extensions, something no other  hydraulic wrench is capable of.

4.HYTORC-XLCT provides continuous turning speed and precise power delivery to the nut in all  applications.


5.HYTORC-XLCT is equipped with a 360x360 degree Uni-Swivel so there is literally no hose kinking  and the tool can be applied even in the most confined areas.

6.Build in withstand the rigors of daily use in heavy industry.

7.Versatile for use with hex, 12 point, castle nut sockets etc.



8.Eight models with torque output upto 59110 ft-lbs.

9. Uni-swivel technology for free movement & positioning of tools & hoses.

10.Available with square drive conversion link for use with hex and allen sockets.

Operations-


Connecting the System
The wrench head and power pack are connected by a 10,000 PSI operating pressure (40,000 PSI burst) twinline hose assembly. Each end of the hose will have one male and one female connector to assure proper interconnection between pump and wrenchheads.
As with other HYTORC models, if the square drive extends towards the right, the tool is set to tighten; if towards the left, its set to loosen. To change drive direction, press in on the drive retainer button, remove drive, place in opposite direction, and replace retainer, insuring it is secure.

TORQUING (tightening) with the XLCT Series and a Square Drive
Place the tool and the socket on the nut, making sure that the socket has fully engaged the nut and that the square drive is fully into the socket. Make sure the reaction arm is firmly abutted against a stationary object (i.e., an adjacent nut, flange, equipment housing, etc.).
By pushing down on the remote control button, the tool’s cylinder will extend and the reaction arm will contact its reaction point. Continue to hold down the button as the socket turns. When the hydraulic cylinder inside the tool is fully extended, the socket will no longer turn, and you will notice a buildup of pressure to the point where the pressure was preset prior to applying the wrench (See SETTING TORQUE).


IMPORTANT: This buildup of pressure after the cylinder is extended DOES NOT INDICATE that this pressure (torque) is being applied to the bolt. It only indicates that the cylinder is fully extended and cannot turn the socket further until the tool automatically resets itself.
Releasing the remote control button will retract the cylinder, and the tool will automatically reset itself. Each time the cylinder is extended and retracted, it is called a cycle. Successive cycles are made until the tool “stalls” at the preset PSI/Torque with an accuracy of ±3%.
IMPORTANT: ALWAYS ATTEMPT ONE FINAL CYCLE TO INSURE THE “STALL” POINT HAS BEEN REACHED.
Should the tool “lock on” after the final cycle, push down on the remote control button once more (to build pressure) and while maintaining this pressure, pull back on the reaction pawl release mechanism. Releasing the remote control button while continuing to hold back on the release mechanism will allow the tool to be removed easily.

Loosening Procedures
First, set the pump to 10,000 PSI. Set the tool for loosening and attach the socket. Make sure the reaction arm abuts squarely off a solid reaction point. Press and hold the remote control button down. Pressure will build up as the socket begins to turn. When the cylinder is fully extended, the socket will no longer turn. Release the remote control button, the cylinder will automatically retract. Repeat this process until the fastener can be removed by hand.
NOTE: If the bolt does not loosen using the above procedure, it is an indication that you will require the next larger size tool to loosen the bolt.

Applications-

It is extensively used in Petrochemical, Railway, Steel, Cement, Power Industry.
