The Liebherr crawler excavator, which runs on a track tractor chassis, is an outstanding and detailed construction model to 1:50 scale. The machine is almost entirely produced in metal and fitted with a variety of play functions. The body rotates. The metal crane arm can be raised and lowered using a swivel lever. The shovel is also height-adjustable using another lever. The shovel automatically opens when lowered and closes again when raised.
