Hoʻokuʻu i ka 420GF photovoltaic drilling rig, ka hopena hope loa no nā hana mauna nui. Hoʻolako ʻia ka mīkini pilang solar me kahi pālahalaha ma ke ʻano maʻamau, ʻo ia ka koho maikaʻi loa no ka hoʻokomo ʻana i nā puʻu photovoltaic nui-aperture a me ultra-large-aperture. Hoʻohana ʻia ka rig drilling i kahi hoʻolālā poʻo rotary kiʻekiʻe me ka torque a hiki i 8000N/M e hōʻoia i ka hoʻokō ʻana i nā pono o nā hana pilang solar Φ176-300-400mm.
