We took a field trip to Gearbox, a facility that rebuilds and reparis the gearboxes found in large wind turbines, in Mukwonago. They gave us a tour of their shop and told us about the process of unloading, dissassembling, cleaning, rebuilding, and testing the gearboxes. We got to see one being unlaoded, as well as other in different stages of being cleaned and reassembled. There was even one hooked up to their testing machinery. Seeing firsthand how large the gears are in the gearboxes was an amazing cool experience. Thank you Gearbox Express!
