Bolt Tensioning Technology for Wind Turbines

WTB Series Fully aware of the difficulties associated with wind turbine blade tensioning, the new TorcUP WTB Series 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 for...

Automatic Tensioner Reset WTB Tensioners are profile cut at the base to ensure they fit onto as many applications as possible. The interchangeable profile cut spacer at the base of the tool gives the tensioner the flexibility to be used on many different applications. The replaceable Spacer is also a good maintenance feature allowing “swap out” of a damaged tensioner base. To increase speed all WTB 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,...

The new WTF is a purpose designed range of hydraulic bolt tensioning tools designed to suit most wind turbine foundation bolting applications. The WTF tensioning tools can be supplied to suit many different All Thread 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 TorcUP WTF range of tensioning tools have been fully site evaluated in the wind energy industry. Short Stroke Foundation...

Suitable Load Capacity for Grade 75ksi & 150ksi All Thread Foundation Bolts. Variable Bar Diameter, Variable Bar Protrusion The amount of thread protruding from a foundation bolt nut can vary significantly from turbine to turbine. To overcome this variation the WTF Bolt tensioning tool is available in both short and long stroke variations. An elliptical WTF tool is also available for use when clearance between the bolt and tower wall is restricted. Long Stud Protrusion Models Short Stud Protrusion Models When the amount of stud protrusion allows, the long stroke tensioner is ideally suited, offering...
