For the first time, ENR has assembled a list of the world's top supercranes, which we found hard at work on almost every continent building powerplants, refineries and other large-scale infrastructure and industrial projects.
Ranked by maximum lifting capacity, we found heavy lifters that can pick up at least 2,000 tonnes all the way up to nearly 7,000 tonnes—about the same weight as 78 space shuttles. Some of these machines stand more than 185 meters tall (600 ft), about four times taller than the Statue of Liberty. The price tags on these machines can run to $30 million or more.
Because it can moderate the damaging effects of earthquakes, base-isolation is a technique used primarily in seismically active regions. ENR takes a look at some of the largest applications of base-isolation technologies in the world.
