Did you know?
Gearbox Express has exceeded growth projections and recently announced its building a 75,000 square foot facility in Mukwonago’s new industrial park, doubling its size, to better meet demand and fulfill its promise to deliver efficient and high quality service to each of its customers.
Gearbox Express (GBX), located in Mukwonago, is the only independent company in North America focused on providing down tower, wind gearbox remanufacturing services. The company focuses strictly on gearboxes and truly knows how to keep them running.
Since its inception in 2010, GBX has been committed to helping wind farm owners protect and manage their assets.
Gearbox Express knew it had to be located in the heart of manufacturing country with easy access to wind farms across the nation. Its current 43,000 square-foot facility is a climate-controlled, near-clean room environment, and home to highly-trained technicians that have extensive experience.
The three founding members of GBX identified a void in the wind turbine aftermarket, seeing an opportunity to “remanufacture and upgrade” gearboxes that were operating for 5-7 years in their original form. GBX analyzed the OEM designs and developed significant upgrades to address these lifespan issues, creating the highest value proposition in the industry.
GBX introduced technical innovations coupled with an intense commitment to customer satisfaction. At the heart of the GBX operation is its 3.1 MW (4,000 hp) regenerative test stand that mimics real-life, often variable, wind conditions. Gearbox Express tests each and every gearbox to guarantee it will run properly. The technology used for and the data-analysis output from our test stand is pioneering and predictive.
At its launch, GBX provided remanufactured gearboxes through its GBXchange program, minimizing downtime and cost for its customers. Now, Gearbox Express is performing contract load testing for multiple parties, providing parts for uptower repairs, and managing customer’s inventory. In addition, they host GBX School; a two-day training for customers focused on gearbox and bearing design, maintenance, failure modes, and light repairs.
