Do you remember how proud you were the first time you built something with LEGO -- without instructions -- that other people could recognise? We're sorry to say it was probably complete garbage compared to ShineYu's fully-functional, remote-controlled Liebherr LTM 1350 all-terrain crane model.
Measuring in at 92cm long and weighing close to 11kg, ShineYu's creation not only looks like a flawless replica, it also works like the real thing, matching the full-sized version on almost every last feature.
It boasts eight wheel steering for manoeuvring around tight corners, retractable support columns for stability and a separate support truck with trailer for carrying the LTM 1350's counterweights. Its rotating main boom can lift 2kg when retracted, and when fully extended it actually ends up being taller than the model's creator.
ShineYu even created custom labels and graphics for his creation, which goes a long way to making it look remarkably realistic, even at this small scale. It definitely puts that rainbow, roofless house you built as a kid to shame.
