Just researched Liebherr's Sales and Service Center in Miami, Florida. It's a state-of-the-art facility opened in 2013 (the tower cranes part is there since 2018). It's near the Port of Miami. Covers 9 acres (3.6ha), the built-up portion is 56,000 square feet (0.5ha). It deals with 3 things: refrigeration and freezers, tower cranes, and maritime cranes (the latter includes floating cranes). It also runs training courses for crane operators, and this includes using simulators (see photo below) that replicate various weather conditions. I could imagine Hadrian operators learning the ropes on such a simulator.
