The LEGO Technic Liebherr LR 13000 42146 has finally, been officially revealed! This is a phenomenal crawler crane! The LEGO 42146 is absolutely massive, standing at a full meter tall. It uses 6 motors, as well as two hubs. The chassis is massive, and I'm certain that it will be a ton of fun to play with. However, each motor drives its own function. There are no gearboxes or any complex mechanisms like that. That is a major downside.
