Hi-Force offers two high performing pumps for your hydraulic tensioner, offering tooling flexibility based on your working environment. There is the AHP-BTU range of air driven hydraulic pump which is ideal for plant work and larger duty jobs. When you run into more remote work applications and there isn’t an air supply that is readily available, the HPX1500BTU manually operated high pressure hydraulic pump will deliver the same 21,750 PSI in a compact hand pump.
How does a Hi-Force hydraulic bolt tensioner work?
A bolt tensioner is placed over a nut & bolt. A portion of the bolt tesnioner called the “thread puller” will be tightented onto the bolt. Once this is secure, the tensioner will be connected to the hydraulic pump where pressure will then be applied. Once pressure is applied, the technician will tighten the nut via the nut collar & tommy bar to “hand tight”. Once this is achieved, the pressure will be relieved from the bolt tensioner and proper clamp load will be applied to the joint.
How do you use a Hi-Force hydraulic tensioner pump?
Please see manual for step by step instructions on how to operate the pump properly.
How long should a bolt be for tensioning?
The rule for this is that you will need at least the length of 1 X the diamater of the stud above the nut for thread engagement.
How do you set a Hi-Force hydraulic tensioner pump?
The way that you adjust the pressure on a hydraulic tesnioner pump is by adjusting the T-Handle which is connected to the pressure regulator.
