FISCHERTECHNIK Liebherr R 938 pneumatic excavator construction kit 576450

The fischertechnik Liebherr R 938 is a detailed construction kit of the well-known Liebherr crawler excavator. The set contains 689 parts and is recommended for ages 10 and up. Once assembled, the model features a fully rotating upper carriage and moving crawler tracks, closely modelled on the real machine.

The highlight is the pneumatic system, which drives the bucket and boom with real air pressure, just as on actual construction machinery. Builders can see how compressed air produces mechanical movement, making the principle easy to understand in hands-on play.

As part of the Technik series, the kit encourages technical thinking, spatial awareness and creativity. All components are made from durable plastic. Because of small parts, the set is not suitable for children under 36 months.
