TENTEC AERO WTF
|
The new Aero WTF is a purpose designed range of hydraulic bolt tensioning tools developed by Tentec and designed to suit most wind turbine foundation bolting applications. The Aero WTF tensioning tools can be supplied to suit many different thread forms such as Williams Inc threaded bars and the more conventionally ISO metric and Imperial Unified Thread forms. These feature packed tensioners have been designed with rapid tensioning in mind and offer a safe, reliable and consistent method to simultaneously tension many Foundation bolts. The Tentec Aero WTF range of tensioning tools have been fully site evaluated in the wind energy industry. |

| Versatile The amount of thread protruding from a foundation bolt nut can vary significantly from turbine to turbine. To overcome this variation the Aero WTF Bolt tensioning tool can be configured to work in two different ways. |
Long Stud Protrusion |
Short Stud Protrusion When the stud protrusion is short an extended length puller can be used which reaches down inside the tensioner to grip onto the short stud protrusion. |
 |
Automatic Tensioner Reset Again to increase speed all WTF tensioners are fitted with a spring mechanism that automatically resets the tensioner once the pressure has been released to zero. The tensioner is then automatically ready to tension the next bolt, no operator intervention is required. |
‘Best Fit’ All Aero WTF tensioners have been designed for use with Structural Hexagon Nuts to DIN 6915 & more conventional nuts to DIN 934. WTF is also designed for nuts that use washers to DIN 6916 & DIN 125. |
| Simultaneous Bolt Tension Multiple Aero WTF tensioners can be linked together with high pressure flexible link hoses to give simultaneous bolt loading. All suitable hoses and connections are available from Tentec. |
