Variable Model Stud Tensioners

Variable stud tensioner models allow the tensioning of different bolt sizes or thread forms while utilizing a common load cell. All that is necessary is to change out the pullers and bridges to accommodate a different size. The versatility of this stud tensioner keeps tool inventory to a minimum.

How The Variable Model Stud Tensioner Works

The operator selects the Puller Bar, Bridge and Nut Rotating Socket for the stud and nut size to be tensioned. After placing the Bridge and Load Cell Housing over the nut, the operator threads the Puller Bar onto the stud. He then connects the Stud Tensioner to the Hydraulic Pump, using Hydraulic Hoses with Quick–Disconnect (QD) fittings. The Hydraulic Pump supplies high–pressure hydraulic oil to the Tensioner Load Cell, producing an accurate axial tension that stretches the stud. When the pump reaches a pre–set pressure, the operator uses a small bar to tighten the nut by hand. He then removes the Stud Tensioner and the process is completed.

Benefits Provided:

  • Trouble-free, No-Leak, Lo-Friction Seals
  • Overstroke Indicator
  • Extra–Long Working Stroke
  • Compact and Lightweight Design
  • Simple to Operate and Maintain
  • Total Quality Assurance
  • Dependable Operation
  • Twin Hydraulic Ports (on standard models)

The illustration shows the Tensioner with an optional drilled nut. Drilled nuts can be hex or round. A Nut Rotating Socket (NRS), that fits inside of the Bridge, and turns a hex nut, is furnished standard.

HTI can work with you to design a custom hydraulic tensioning system that will fit your hydraulic tensioner application when standard models won’t. We also provide fixed stud tensioners and hydraulic nuts and pumps. Let us help you with your hydraulic tensioner applications including Cell Tower Hydraulic Tensioning.
