Huib van der Hart is a master of large LEGO cranes. His latest effort is a Liebherr LTM 1750-9.1 mobile crane owned by Northwest Crane Service. At 1:16 scale, the model packs in loads of detail, and Huib tells us the crane uses close to 15,000 pieces, is over 4 feet in length and weighs 33 pounds. It’s even completely drivable with 18-wheel steering thanks to LEGO Power Functions. This isn’t Huib’s first humongous crane, either, as he previously built this crane’s sibling, the Liebherr LTM 11200 9.1. He’s continuing to work on the 1750 model, and has plans to make the boom arm fully extendable.
