LEGO Technic Rough Terrain Crane 42082 contains 4,057 pieces and builds a large mobile crane with eight wheels. The model features four-wheel steering, extendable outriggers, a rotating superstructure and a telescopic boom that can be raised and extended. An included Power Functions motor powers several of these functions and the winch raises and lowers loads. The cab contains a seat and controls, and the set also includes elements for building sections of a building and moving them with the crane. The extended boom reaches a considerable height above the vehicle.
