Wind Multi-Stage Hydraulic Tensioner
Hydraulic tensioning is the ideal method for tightening bolted connections. Hydraulic tensioning eliminates inaccuracies and helps achieve correct bolt loading in critical connections. At HTI, we’ve been building hydraulic tensioners and nuts since 1986.
Multi-stage tensioners are ideal for applications that are radially limited. They provide a large amount of stroke in a radially compact package by using two or more stages, one on top of the other, both pulling on the same load.
HTI multi-stage tensioners can be standard or spring return. HTI multi-stage tensioners are available in standard sizes (studs up to 6” in diameter) or large stud sizes (up to 16”).
HTI Multi-Stage Tensioner Features:
Many of our standard tensioner features also apply to multi-stage tensioners:
- Tensioners can be standard or spring return
- A through-hole option for use with a separate puller nut
- A gearbox for ease of turning the load nut
- Single or twin (for chaining) hydraulic couplings
- Overstroke indicator and stop
- Long stroke
If one of our standard catalog models doesn’t work, we can design a custom tensioner for any fastening application. Some varieties of single stage tensioners are:

Custom Engineered Tensioners Since 1986
HTI has been designing engineered solutions to your toughest bolt tensioning problems since 1986! You can choose from one of our standard catalog sizes above, or we can design a custom fixed tensioner for any application when a standard model won’t work. HTI tensioners can be designed for imperial or metric-sized studs, high loads, high temperatures, large stud sizes, or corrosive environments. Our multi-unit tensioning systems can make easy work of large bolted systems, and our automated tensioning systems can reduce labor and increase throughput in high-volume manufacturing applications.
