TITAN AUTO TENSIONER

TITANS Patened Auto tensioner has a electric, or hydraulic motor. This motor will automatically wind the bolt down at the same time the bolt is tensioned!! Can be operated via remote controlled for nose cone tensioning in windmills!!!

How do you know the load your applying is correct? Simple...The Tensioner is a Calibrated Device. The cylinder in the Tensioner is calibrated to "Stall out" (stop moving) at a certain load, and that load is achieved exactly at specified hydraulic pressure. This works exactly like a Hydraulic Torque wrench, but much more accurate.

I understand that the stud stretches.But how do you know your applying the correct load on the stud?

For Example..The hydraulic pump used on the bolt tensioner has a regulating valve inside of it. For example If I wanted 20,000Lbs of clamp load on a particular bolt. I would look at the Pressure VS. Load chart. The chart may say 20,000Lbs = 16,500PSI setting on the pump. So the cylinder in the Tensioner is calibrated to achive 20,000Lbs at 16,500 pressure of hydraulic fluid in the cylinder of the tensioner. Its Simple Math. This is the same principle that a Hydraulic Torque wrench uses.

I would look at the Pressure VS. Load chart. ? now that's the chart for that specific pump correct? or is the there a standard chart for all tentioning pumps?

[WWWNIBTORQUECOM]

You have it backwards. Just think of it just like a hydraulic Torque wrench. The is the chart for the specific Tensioner. The pumps are universal, and have the capibility to reach up to 30,000PSI. The pumps have a regulator inside of them. You set the pressure on the pump according to the load required on the hydraulic tensioner. The pressure vs. load chart is calculated by the diameter of the cylinder inside of the tensioner. Its very easy.

how do you know what pressure you put on the bolt?

[WWWNIBTORQUECOM]

The pressure I am assuming your speaking of the load the bolt is holding (thousands of lbs - also refered to as KIPS.) since the tensioner is pulling the bolt thru hydraulic pressure. you set the hydraulic pressure. Hydraulic tensioning is accurate within 0.5%. it is the most accurate way to apply clamping load to a threaded fastener. There is nothing more accurate in the world.

1 1/2 bolt diameter - .2 k-factor - 25k - what is the ft pounds?
