Making The Rain Go Away At Miller Park With Nook Electric Cylinders

As the world's leading authority on large-scale motion technology, Uni-Systems was a natural choice for solving a persistent water problem at Miller Park, the new home stadium of the Milwaukee Brewers in Milwaukee, Wisconsin. Miller Park, which opened at the beginning of the 2001 baseball season, features a retractable roof that opens to provide a panoramic view of the Milwaukee skyline. Opening the roof involves rotating five massive pie-shaped panels around five individual pivots. During stormy weather, the roof leaked in the outfield area, prompting the Southeast Wisconsin Professional Baseball Park District, which owns Miller Park, to search for a consultant to stop the leaks. With extensive experience in the motion of large structures and weather-sealing methods, Uni-Systems was chosen to solve the water leakage problem. ?e solution Uni-Systems developed included a combination of installing seals on the large existing panels and adding four additional six-foot-by-20-foot doors, according to John Lanari, project manager for the Miller Park project at Uni-Systems.
