Liang-Dortmund mining rig

The Liang-Dortmund mining rig is a large mobile ground-based mining rig manufactured by the Liang-Dortmund Corporation to be used for surface mining and processing on Meridian.

Specifications
The Mining Rig is the largest known UEG ground-based vehicle known as of yet, rivalling even some naval warships. More akin to a landship than a typical vehicle, these mobile Mining Rigs dwarfed even the Mammoth in scale. The rig itself has several levels. The large bridge was located at the top-front of the vehicle where the drivers and crewmen oversee the operation of the rig.

In the center bore a large boring laser that could penetrate the petrified soil of the glassed surface of Meridian. Materials can then be either extracted or lifted on the top deck via two cranes at each end of the vehicle.

Moreover, the deck levels were big enough to house an elevated landing platform that can fit a Brahman light hauler for surface-to-space resource extraction to any nearby orbiting spaceships for interstellar trade. The ship itself is powered and moved with four large threads and six wheels over the glassy surface of the planet.

Trivia

 * The Halo 5: Guardians multiplayer map, The Rig, is based on the open decks of one of the many rigs on Meridian.
 * There is an easter egg where one of the rigs would be swallowed up by a Sandworm. This is a clear reference to the franchise, Dune. To trigger the easter egg, the protruding platform in the center pit of the map must be broken (such as by a ground pound). This will raise two explosive cores from their cowlings on the perimeter of the map. Destroy both of these cores and watch the mining platform by the sunset.
 * It is unknown how large the rig is, although rough estimates from the concept art and from the map itself put it at the excess of over 100+ meters.
 * Due to its size and its mining nature, it could be considered the UEG equivalent of the Type-58 Harvester.
