LEGO [Technic] - Crawler Crane Building Set (42042)

Take on massive construction projects with the impressive LEGO Technic Crawler Crane (42042), a highly detailed motorized building set designed for fans of realistic engineering and advanced LEGO mechanics. This powerful 2-in-1 model faithfully recreates a heavy-duty crawler crane with authentic working functions, delivering an engaging building experience followed by hours of interactive operation. From lifting oversized loads to maneuvering across rough terrain, every feature captures the strength and complexity of real-world construction equipment.

Powered by the included LEGO Power Functions motor, the crane features motorized caterpillar tracks, a rotating superstructure, a lifting boom, and a fully functional winch system with an opening claw.
