Visit Komatsu's new Harbor District facility facility that produces the major components of large mining machines, including electric rope shovels, hybrid shovels, draglines and blasthole drills.

Doors Open Weekend Experience

Stop in to Komatsu’s Customer Experience Center, where you can walk into the company’s 360-degree theater for an immersive video experience that captures the size and scope of the massive equipment Komatsu engineers and manufactures for mining customers around the world. Enter the experience through a massive replica bulldozer blade and see how Komatsu can track equipment across the globe. During your visit, you’ll get a taste of past, present and future, as you get up close with historical items from the company’s P&H brand (founded in Milwaukee in 1884) and see how equipment design has evolved to support society’s ever-growing needs for essential minerals. Pose for the camera at the Komatsu selfie station to show your friends how past became present right here in Milwaukee.
