What's the name of the elevator in Wandering Earth 2?

Space ladder. In the story of Wandering Earth 2, humans built a ladder near Libreville, the capital of Gabon, called the space ladder. Libreville is almost on the equator, but the standard ladder needs to be built on the equator. Because the space station is above the equator, the ladder is built on the equator, which ensures the synchronization of the upper and lower positions, and can rely on the acceleration generated by the centrifugal movement of the equator of the earth to maintain the force balance between the ladder and the gravity of the earth. The so-called space elevator, sometimes referred to as space elevator, is an imaginary way to enter space. Ordinary buildings and ladders have insufficient compressive strength, and when piled up less than a few kilometers high, they will collapse, and they cannot directly rise into space like pea vines in fairy tales. The tensile strength of many materials is far superior to the compressive strength. If humans build a ladder in synchronous orbit with very stretchable materials and hang it on the ground, it will be relatively static with the ground, so it will climb into space along this ladder.
