Yazisa i-420GF ye-photovoltaic drilling rig eguquguqukayo, esona sisombululo sisesona sisombululo sisentabeni. Umatshini wokupakisha welanga uxhotyiswe nge-spreader njengesiqhelo, eyona nto ingcono kakhulu yokufakela i-aperture enkulu kunye ne-ultra-large-aperture photovoltaic piles. I-drilling rig ithatha i-torque ephezulu yoyilo olujikelezayo kunye ne-torque ukuya kwi-8000N / M ukuqinisekisa ukuba ihlangabezana neemfuno ze-Φ176-300-400mm imisebenzi yokufaka i-solar.
