Our own Rich Maloney, Department Manager for Structural Services, has been providing structural engineering support services for over 100 theme park rides, including five of the top six roller coasters nationwide according to Time Magazine’s “2013 Top Ten Roller Coasters in the US”! He was recently published in the October issue of Civil & Structural Engineer “Zumanjaro: Drop of Doom – How Scary is Built”. At 415’ vertically, the Zumanjaro: Drop of Doom drop track was designed to fit on the face of the existing steel tower that supports the vertical loop of the Kingda Ka roller coaster at Six Flags Great Adventure. The ride hauls thrill seekers to the top of the tower in three gondolas in less than 30 seconds, then the gondolas descend simultaneously, dropping independently in less than 10 seconds and up to 90 mph. The Zumanjaro ride required making modifications to the existing Kingda Ka tower footings and an additional 226,226 lbs. of structural steel reinforcement. Read more.
