Supermashiny Moon
At the bottom contours of a large crater, if mentally take him for a clock, seen in half of the third object is "ruffled" Perhaps this is the impression of its structure, although the object of such size, quality made, should be to retain strength at a very low weight. This is a basic principle of the triangles used in the TV towers and cranes, built of beams and struts, rather than solid structures.
Here is the object inside the crater. Object has a swivel just at the point where the hinge should be. Two beams rising from the ground - very straight and parallel (protruding elements). There is something like a rope, up and down the horizontal part of which goes to the bucket. There is also a long thin device that goes from the base object down the hill toward the center of the crater and the ends of the oblong plate. This can be seen everywhere on the Moon and, possibly, a connection to a source of energy.
Equipment of this size - a few miles in length with moving parts - quite accessible to our technology on Earth. We are building a subway, jetliners, cars, flooding the city. We are building a dam a few miles long. But we were on our needs do not have to build mining equipment longer than a few yards.
Think about the moon, its inhabitants and their possible uses. If they develop craters and nearby there is no settlement, there is a sense in the great equipment. They need to get the element widely distributed in the cortex of the lunar surface, but one that intensely mixed with other elements. A thought of nickel or aluminum, or gaseous elements such as oxygen and hydrogen. Then they have to sift through, or melt (or something. Still processing) a huge amount of soil per unit time. Or maybe they dig up from the consequences of the catastrophe that has struck them a long time ago? Whatever their purpose, the object is, the crater obravnen and formed again. Most of the breathing space activities and the creation.
