The MITU engineering excavator is constructed of more than 900 building blocks. The length, width, and height of the entire vehicle are 44x15x15.5cm, which restores the shape of a real vehicle and fully displays the charm of the mechanical structure. The bucket and body height can be moved, and the mechanical arm adopts an imitation hydraulic device and can be lifted and retracted freely. It adopts the crawler-type traveling method and has excellent obstacle surmounting ability. The track components are made of lightweight and high-strength materials and are equipped with reinforced anti-skid ribs to improve the strength and grip of the track shoes.
