We’ve got you covered. We are a leading independent service provider in the hydraulics industry, and our team of hydraulic repair veterans has the know-how and state-of-the-art technology to help get your hydraulic components — and your wind turbine — back up and running in no time.

When you send us your hydraulic unit, we guarantee:

  • We will only use genuine OEM replacement parts for repairs
  • We will thoroughly test the unit on our test stands
  • We won’t ship it back to you until its performance meets or exceeds the OEM specs

We have repaired pumps and motors for customers all over the world, and we are proud of our track record. It doesn’t matter where you are, what type of turbine you have, or what kind of hydraulic unit you need to have fixed. We know hydraulic repair for the wind energy industry, and you can trust us to help you get back up and running in no time.

We will test your component on our state-of-the-art test stands, which are calibrated to meet ISO certification and traceable to NIST. Learn more about our test equipment and the flexible service options we have to offer.

Wind Turbine Repair for Top Brands

We offer hydraulic repair for all of the major wind turbine manufacturers, including:

  • Siemens
  • Vestas
  • GE
  • Enercon
  • Nordex
  • Senvion
  • Goldwind

Wind farms depend on wind turbines from these manufacturers and machinery from other heavy equipment OEMs to harvest and store energy. The energy is then transported to the grid through electrical substations that are usually located at or near the farm. Today, there are roughly 1,800 wind farms throughout the United States, generating nearly 90,000 MW of power capacity. As of 2018, the five largest wind farms in the United States were:

  • Alta Wind Energy Centre (Tehachapi, Kern County, California)
  • Los Vientos Wind Farm (Lyford, Texas)
  • Shepherds Flat Wind Farm (near Arlington, Oregon)
  • Roscoe Wind Farm (near Abilene, Texas)
  • Horse Hollow Wind Energy Centre (Taylor and Nolan County, Texas)

A Growing Market

As the wind market has matured, a complex supply chain has grown, which includes OEMs that manufacture key components like blades and towers. Turbine assembly is also a key part of the supply chain. Thanks to advancements in materials, automation, and the manufacturing process, domestic manufacturers have been able to significantly increase production. Today, more than 80% of domestic wind turbines are manufactured and assembled at plants in the United States. However, in order to expand wind farms into more suitable areas, using larger, more advanced turbines, manufacturing capabilities, and assembly techniques need to be developed. In other words, there is still significant room for growth in the wind industry.

Hydraulics in Wind Turbines

Hydraulics are used in wind turbines to help produce the high pressure needed to turn the rotor blades. When it comes to powering wind turbines, hydraulics are more effective than electricity because hydraulics can produce more power and energy, and don’t require the use of fossil fuels.

Hydraulic systems also tend to be more reliable and cost-effective than traditional electrical drivetrains. Hydraulic drivetrains also tend to be much lighter, which helps reduce the vibrations created by the movement in the rotor hub. This reduces wear and tear on the entire system, and can help extend the lifetime of important components. Hydraulics are used for specific applications in each wind turbine, including:

  • Pitch control
  • Braking systems
  • Drivetrain

Hydraulic Repair Services for Wind Turbines

You need to protect your investment in your wind turbines and wind farm equipment, and we’re here to help you with that. We’re going to specialize in the repair of the hydraulic pump that is attached to the main shaft in the tower, but we can also help with valves, motors, rotary joints, and any other components that require hydraulic power.

Premium Service Options

Same Day Repair Service

For units that we have repair stock on hand, we can offer our Same Day Service program. If you request one of these units or your unit to be repaired is received by 10:30 AM we can have it ready to ship by 5:00 PM that same day.

VIP Service (24-Hour Rush Service)

The price is agreed upon and approved before the unit is shipped to us for repair. Once the unit is received, it is inspected, rebuilt using genuine OEM parts, tested, and ready to ship within 24 hours.

Keep On Moving Service (KOM)

An average repair price is established, agreed upon, and approved before the unit is sent to us for repair. Once the unit is received, we inspect it, rebuild it with genuine OEM parts and test it out in our shop during our normal schedule. When it passes testing, we send it back to you.

Key Components of Wind Turbines

Wind turbines are made up of more than 8,000 sub-components. Manufacturing a turbine involves metal fabricating, casting, heat treating, machining, and grinding. However, the four main components of a wind turbine are:

Generator

Generators are the driving force behind the electrical current that is passed from the wind turbine to the power lines that lead to the electrical grid.

Nacelle

The nacelle houses the generator, which includes key hydraulic components such as the brake assembly and gear drive.

Tower

Towers can vary in height, but they are usually coated with a zinc-based finish and layers of epoxy and urethane to protect them from the weather.

Rotor Blades

The massive blades on a wind turbine can spin as fast as 160 mph, so they need to be sturdy. They are constructed with hundreds of layers of wood, fiberglass, resin, and carbon.
