LEGO Technic 42100 Liebherr R 9800 Excavator

LEGO Technic set 42100 depicts the Liebherr R 9800 Excavator, a large tracked construction machine.

Set 42100 recreates the Liebherr R 9800 within LEGO Technic, focusing on a heavy excavator rather than a road vehicle or racing subject. It belongs with the licensed construction machines in the theme, where the appeal comes from the vehicle’s structure and its working movements.

Its build covers the tracked base, rotating body, boom, arm and bucket. The set is known for app controlled remote functions, used for driving the excavator and operating its main digging movements.

This is a set for Technic builders who want a functional construction model for display, controlled play or collection. Among Technic sets, it sits with the large specialist machines and is especially relevant to collections built around construction equipment, licensed vehicles or remote controlled functions.
