Boltight has been at the forefront of hydraulic bolt tensioning for over a decade. Our tensioning tools provide fast, accurate and safe solutions to tighten and loosen multiple bolts simultaneously.

Boltight solutions for Wind

Our designs are lightweight, robust and low maintenance – perfect for work in harsh environments.

With heights of up to 460 feet (140 meters) and blades reaching over 60 yards (55 meters), wind turbines are the largest application within the renewable energy sector. Although their size allows them to produce more energy, it also makes them more difficult to build and maintain. Working at height makes safety paramount. Tools must be small and lightweight to carry up the wind tower and be able to fit in restricted spaces. Offshore windfarms are difficult to access and tools must be reliable and easy to maintain.

Our wind industry equipment is tried and tested as a reliable tensioning solution for critical joints on offshore and onshore wind turbines and associated structures. The superior quality of Boltight products ensures continued performance throughout high cycle usage, without the need for frequent maintenance and repair. Engineered for many applications on OEM turbines, our tools are incredilbly popular with construction and installation contractors and inspection and maintenance providers around the world. We are specialists in the design of hydraulic bolt tensioners for the wind industry and understand your special requirements.

Our tools are used in the following sections of a wind turbine:

  • Foundation bolts
  • Gearbox bolting
  • Tower bolting
  • Nacelle frame
  • Front and rear main bearing and blade to bearing
  • Nacelle yaw bearing
  • Blades
  • Main shaft to hub

Boltight tools have been engineered to suit the technical requirements of major OEM wind turbine manufacturers, including Vestas, Gamesa, GE, Nordex, Siemens, RE Power and Mitsubishi Heavy Industries. 

Standard solutions

The Typhoon multi-stage range has been designed to deliver high bolt loads in tight spaces. This makes them ideal for use within confined radial spaces. Typhoon single-stage bolt tensioners offer high bolt loads in vertically restricted spaces and provide the same user-friendly features as the multi-stage tensioners. Our range of Foundation tensioners cover the majority of foundation and anchor bolts with just two different heads and modular bridge assemblies.

Customized solutions

Over half our tools are bespoke, we can create the right tool for any challenge. Working with our customers from the wind sector we have continuously developed new ways to deliver cost effective solutions for numerous bolting applications and if we don't have a standard tool for your challenege we'll make it - fast!
