Did you know that the very first LEGO Technic mobile crane was released more than 40 years ago? The lovely 855 Mobile Crane became the eighth product in the Technic lineup since its start in 1977. Despite its simple design, it had every essential function of a real machine. A handful of mobile (and stationary) cranes have been released since then. The year 2020 brings yet another one, 42108 Mobile Crane. During the previous decade, the variety of LEGO Technic pieces have evolved a lot, and multiple new mechanisms have been introduced, too. The question is, how many of those new concepts are implemented in the latest set and how different is it from the previous versions of mobile cranes? Let’s build and test this 1,292-piece set, which retails at US $99.99 | CAN $139.99 | UK £89.99, and find out if it is worth a purchase.
