SL-HT Wind Turbine Tensioners

Hydraulic tensioning is the ideal method for tightening bolted connections. Hydraulic tensioning eliminates inaccuracies and helps achieve correct bolt loading in critical connections. At SOLY, we’ve been building hydraulic tensioners and nuts since 2007. The SL-HT tensioners are a purpose designed range of tools to suit all applications in wind turbine manufacturing and operations. These tensioners offer a  reliable and consistent method of simultaneously tensioning multiple joints and have an integrated fail safe design to enhance workplace safety. Designed for special needs such as small space, large load, long life and fast speed, meeting ENISO898:1999 standards;

Features of Wind Turbine Tensioners

Our Single and Dual-Stage Wind Turbine Bolt Tensioners offer a number of features, including:

  • Lightweight and compact
  • Automatic piston re-stroking, over-stroke protection and gearbox nut rundown
  • Swivel 90º Elbow connections are also available

 

 

Durable and Secure Wind Turbine Bolts

Wind turbine hydraulic tensioners are a critical item in the proper functioning of any wind turbine. These tensioners are needed to tighten and tension the turbine’s bolts to their required torque.
SOLY  is not limited to one type of wind turbine bolting application. We offer Single-Stage and Multi-Stage tensioners that have been engineered for OEM Wind Turbines, including: Nacelle Frame Bolting, Blade Bolting, Tower Bolting (mid and upper sections), Bearing to Hub Bolting, Hub to Spindle Bolting, and much more. SOLY’s Wind Turbine Bolt Tensioners are being used across the wind service industry,our customized solutions are applicable on a wide range of wind turbines.

 

Wind Turbine Bolting Applications

SOLY’s Wind Turbine Hydraulic Tensioners have been used to tighten various parts within the wind power industry, such as:

  • Blade to Hub Bearing
  • Front Foot to Base
  • Base to Yaw Bearing
  • Yaw Bearing to Tower Top
  • Rotor to Gear Hub
  • Hub to Main Shaft
  • Tower Segment Flanges
  • Foundation (Base Bolt) Studs
  • Foundation Stud testing

 

Foundation Tensioners

Foundation stud tensioners for wind turbines often utilize a standard Hex Nut from the application as the reaction nut to tension the stud.

Technical Details of SOLY HT Wind Turbine Tensioners

The SOLY HT Wind Turbine Tensioners are engineered with advanced hydraulic technology, ensuring precision and reliability even in the most demanding environments. The tensioners are used to apply controlled, consistent force to wind turbine bolts, ensuring that they are tightened to the correct specifications for optimal performance.

1. High-Pressure Performance

One of the standout features of the SOLY HT Wind Turbine Tensioners is their ability to operate under high-pressure conditions. Wind turbines are typically installed in harsh environments, where mechanical failure due to improper tensioning can result in costly downtime and safety hazards. The SOLY HT tensioners are designed to perform in high-pressure environments, offering exceptional reliability in wind turbine installations and repairs.

  • Maximum Pressure: The SOLY HT Wind Turbine Tensioners can withstand operating pressures of up to 1500 bar, making them capable of tightening bolts with high precision and ensuring proper tension for secure turbine operation.

2. Ergonomic Design for Easy Handling

The SOLY HT Wind Turbine Tensioners are designed with ergonomics in mind. With a compact and lightweight design, these tools are easy to handle, even in confined or challenging spaces typically found on wind turbine installations. This user-friendly design reduces operator fatigue and improves efficiency during bolt tightening tasks.

  • Ergonomics: The tensioners feature a well-balanced design with convenient grips, making them ideal for long-duration operations where comfort and ease of use are paramount.

3. Versatility for Various Bolt Sizes

The SOLY HT Wind Turbine Tensioners are versatile tools that can be adapted to a wide range of bolt sizes commonly used in wind turbine assemblies. From smaller bolts in the nacelle to larger bolts in the tower and foundation, these tensioners can be used for a variety of applications.

  • Range of Bolt Sizes: The tensioners support multiple adapters and are suitable for bolts ranging from M16 to M100, ensuring flexibility and ease of use across different components of the turbine.
