MSJ-06II-ED Tieren Zhizhu

The MSJ-06II-ED Tieren Zhizhu is highly specialized mobile suit, adapted specifically for defending the Human Reform League's orbital elevator. The Zhizhu (Mandarin Chinese for "Spider") is equipped with six wheels which allow it to move up and down on the cables of the elevator. Four of these wheels can also be fitted with tires, allowing the Zhizhu to operate on the ground.

Its main weapon is a 200mm linear cannon, making it the first HRL design to utilize what had long since become standard technology on Union and AEU mobile suits. However, the introduction of the GN-X and its far superior GN beam rifle meant that the Tieren Zhizhu was also the last HRL mobile suit equipped with a linear gun.

With the unification of the HRL into the Earth Sphere Federation, the Tieren Zhizhu was used to defend all three oribital elevators.
