Miller Park, the retractable roof baseball stadium for the Milwaukee Brewers, would have been impossible to construct without cranes. A crane called “Big Blue” was used to lift portions of the large roof panels into place until it failed catastrophically on July 14, 1999 killing three ironworkers. After a lengthy delay, construction continued when a Demag CC12600 crane was brought to the site.
One of my interests has always been cranes. I’ve attempted to make large Lego cranes in the past but wasn’t very successful. In July 2008 I purchased the new Lego Technic “Crawler Crane” Set 8288. After building the set I knew it was the basic crane design I needed so I purchased two more. I began constructing a large crane to represent the Demag CC12600 used to build the real Miller Park.
The resulting crane looked good but was highly unstable. A little load resulted in it falling over sideways in a way similar to Big Blue. I left the model assembled but pushed it aside so I could focus on building Miller Park.
In mid January 2008, I went back to work stabilizing the crane so it could be displayed with my Miller Park model at the Milwaukee County Domes. I continued researching the actual crane and used Thomas Avery’s 12 foot tall crane as a key reference.
After some experimentation I added grey bricks between the lattice to reduce the amount of side to side sway. To make the crane more realistic I also modified the base and crane boom / jib connections. The resulting crane is much more stable and can easily hold the weight of two Lego motors. It has three hand cranks which operate the main hook, main boom height, and jib height.

This is one of my first attempts at big cranes. It is actually based on "Big Blue's" design. Miller Park Version 2 is also pictured.
This is my original Demag CC12600 crane. It was highly unstable and had two sets of crawlers unlike the real version. Miller Park Version 4A is also pictured.
