An 850-ton Engine
These days, it's tough even for the record books to keep up with stupendous moving feats, so the newest trend seems to be for folks who move big objects to toot their horns by posting videos on YouTube. One example of that is the Texas Department of Transportation, which in 2010 moved a 850-ton (771.1-metric-ton) Toshiba steam turbine engine from the Port of Houston to a power plant in Riesel, east of Waco.
In order to move the machine, officials had to put together a custom rig consisting of two truck cabs and a total of 520 tires. The unwieldy vehicle stretched the length of a football field but was just 39 feet (11.9 meters) wide. It hauled the massive engine about 250 miles (402 kilometers) on state roads and across 82 bridges at a speed of about 10 miles (16 kilometers) per day, according to a video posted on YouTube by the department, which claims that the turbine represents "the heaviest load that has ever been moved this distance in Texas" [source: TxDOTpio].
