New Enerpac, FTE-Series, Elliptical Foundation Bolt Tensioners

The New Enerpac FTE-Series, Elliptical Foundation Bolt Tensioners are designed to fit both standard and narrow access foundation applications.

Similar to the standard foundation bolt tensioners, the Elliptical tensioners were designed specifically for foundation fastening applications on wind towers, and utilize the existing hex nut as a reaction point in order to eliminate thread fit misalignment.

Unlike standard FTR-Serees Tensioners feature an elliptical geometry, which enables fit in narrow access foundation applications without reducing loading capabilities. Operators can easily access the nut with a Tommy Bar rather then employing the use of an offset rundown gear.

These tensioners are ideal for close clearance applications or as universal tools that will work in nearly any foundation application whether it be standard or narrow access.

Max. Load Capacity: 761,1 kN
Max. Operating Pressure: 1500 bar
(Max. pressure varies, see specifications table for more details)
