LEGO Technic Bucket Wheel Excavator is the largest LEGO Technic set to date and a perfect gift for those who love a building challenge. This 2-in-1 model faithfully re-creates a real-life mining excavator with a dark blue and yellow colour scheme, hand-railed walkways, huge tracks, and a detailed cab. The Power Functions motor activates the conveyor belts, rotates the massive superstructure, and manoeuvres the colossal machine into position. Activating the boom lowers the gigantic, digging bucket wheel and conveys the mined material to the waiting mine truck. The finished model is worthy of display on a shelf or desk, or can be rebuilt into a Mobile Aggregate Processing Plant. Rebuilds into a Mobile Aggregate Processing Plant. Rotating bucket wheel.
