Similar to ACU-BREEZE™, ACU-TERA™ can be supplied in either single or dual acting configuration, to take advantage of either existing methodologies, or fastest and best practice, respectively. In single acting mode, customers can benefit from familiarity; however it is in dual acting configuration the benefits of ACU-TERA™ are truly realised.

No other foundation bolt tensioner can offer its operator same speed of actuation and retraction, nor guarantee a faster ‘bolt to bolt’ working regime – essential for customers looking to achieve a faster quota with so many bolts to tension.

ACU-BREEZE™ is much faster in operation than its peers. Utilising power hydraulics for both advance and retract phases provides a much faster tension/reset cycle.

With fewer static and moving parts, ACU-BREEZE™ is simpler and faster to maintain; all the while compromising neither durability nor fatigue life.

ACU-TERA™ is much faster in operation than its peers. Utilising power hydraulics for both advance and retract phases provides a much faster tension/reset cycle. With neither durability nor lifespan compromised, ACUTENSION product offering is designed to keep on working, where most others fail.

ACU-TERA™ is available in a variety of foundation bolt/rebar threadforms, not limited to:

  • Standard metric
  • Standard imperial
  • Dyson
  • Dywidag
  • Fatbar
  • Macalloy
  • Williams
  • Bespoke

ACU-TERA™ tensioners draw upon the benefits of our other patented dual acting ranges (ACURA™, ACU-BREEZE™) to assure best-in-class performance and an effortless tensioning cycle. Coupled with our range of ACU-HERO™ single or dual acting hydraulic pumps, there simply is no faster or smarter way to work.

Such is the success of ACU-TERA™ that it enjoys several OEM approvals, and can easily be customised to suit practically any wind-turbine foundation frame.

Similarly, ACU-TERA™ has been successfully used on several civil projects requiring long stroke, such as bridges and prestressing applications as well as concrete reinforcement tensioning.
