 
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.
| Main Wind Turbine bolted applications |
| • Rear Main Journal Bearing |
• Main Shaft to Hub |
| • Nacelle Frame Half Joint |
• Blade to Hub Slew Ring |
| • Nacelle/Slew Ring Bearing |
• Front Main Journal Bearing |
| |
• Intermediate Tower Bolting |
Swivel movement ensures versatility and operator comfort
Due 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-down
The 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 wrench can be used to rapidly seat the nuts and tensioner. |
