The most complicated Lego building block is the Mercedes-Benz Arocs3245 truck model. This is made by Lego and Daimler, and it is one of the most complicated products in Lego history. This Arocs3245 model needs to be assembled from 2793 parts, including some pneumatic devices. The size reaches 540/240/3 10mm, which is more than half a meter of fuselage. It has a newly designed four-axis multi-link suspension, and the vehicle support is enough to reach the boom workbench.

The most complicated Lego building block assembly strategy

The biggest difference between the mechanical group and other Legos lies in the combination of pieces, blocks and bars, just like traditional building blocks, while the products of the mechanical group are mostly the combination of bars and bolts, which have more flexible changes and activities, and there are also many gears to realize the activities of finished products.

Due to too many parts, Lego is divided into six parts, 1 part is the front frame, the second part is the complicated gearbox in the middle, the third part is the rear frame, the fourth part is the mechanical grab arm, the fifth part is the cab, and the sixth part is the hopper. The hardest part is the second and fourth part, and the simplest part is the sixth part.
