Bucket Wheel Excavator
42055-1 Technic 2016 3929 parts 1.2% catalog rarity Advanced
The LEGO Technic 42055-1 Bucket Wheel Excavator replicates a real-world mining machine. This 3929-piece model, a substantial set from 2016, features a dark-blue and yellow color scheme. Power Functions components integrate to activate several motorized actions, including the rotation of the superstructure, the movement of its tracks, and the operation of conveyor belts. A boom lowers the bucket wheel, which then conveys material into an included mine truck. Builders can also deconstruct this machine and reassemble it into a Mobile Aggregate Processing Plant, providing an engineering challenge.
