Look forward to a mindful building project with the LEGO Technic Volvo EC500 Hybrid Excavator (42215) from this set for adults. But building is just the beginning, as the model has many functions and is motorized. Use the motor and transmission to explore the functions and put the excavator to the test. With the lever, you can select four functions that move the boom and arm, the LEGO hammer, and the bucket. The doors to the cab, the tracks, and the upper structure of the excavator can be moved manually. The realistic movements of the model make this set a great gift for adults who enjoy building more complex LEGO vehicles or construction machinery. LEGO Technic building sets for adults allow you to fully indulge your passion for powerful machines while providing a relaxing building experience. A building instruction manual is included with the set. A digital version of this manual is also available in the LEGO Builder app. The set consists of 2,359 pieces.
