Tentec aero wtf strekkeverktøy

Wind Turbine Tensioners

The 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 All Thread Bars and the more conventional 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.

Optional Geared Nut Run-Down

Tentec offer a gear nut run-down mechanism which provides a very rapid and consistent way of seating the foundation hexagon nuts during the tensioning procedure. A common 1/2" Square drive hand torque wrench can be used to rapidly seat the nuts to the recommended 30Nm (max) torque. Alternatively Tentec offer the same foundation tensioning tools but with manual nut run-down.

​Limited Space Option

A unique elliptical WTF tool is also available for use when clearance between the bolt and tower wall is restricted.

​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 ready to tension the next bolt, no operator intervention is required.
