Fully aware of the difficulties associated with wind turbine blade tensioning, the new Tentec Aero WTB is a purpose designed range of hydraulic bolt tensioning tools to suit most wind turbine bolting applications. All WTB Tensioning tools have the capacity to achieve the specified proof load requirements as detailed in EN ISO 898-1:1999 and ASTM A490M for grade 10.9 Bolts. These feature packed tensioners have been designed with rapid tensioning in mind and offer a safe, reliable and consistent method to simultaneously tension many bolts.


Swivel movement ensures versatility and operator comfortDue to the very limited space available in many blade bolt compartments and to help where many tensioners are connected together every Aero WTB tensioner has the option of a 360º swivel connection. This 360º swivel operation allows the hydraulic hoses to be positioned in the best possible position to allow open access to the tensioning tools.
Geared Nut Run-DownThe inclusion of a gear nut run-down mechanism offers a very rapid and consistent way of seating the 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 required 30Nm (Max) torque.
Geared Nut Run-DownAt the heart of all Aero WTB tensioners is the Puller. Manufactured from high grade aerospace material and carefully designed to give the maximum possible life. All Aero WTB tensioners have a feature that ensures the tool fails safely in the unlikely event of a puller failure.
Again to increase speed all Aero WTB tensioners are fitted with a spring loaded device that automatically engages the tensioner drive socket with the hexagon nut. The operation is completely transparent to the operator and no time is wasted aligning the tensioner with the nut.
