Fa'alauiloa le 420GF photovoltaic drilling rig, o le fofo sili lea mo galuega tetele o mauga. O loʻo faʻapipiʻiina le masini faʻapipiʻi la i se faʻasalalauga e pei o tulaga masani, o le filifiliga sili lea mo le faʻapipiʻiina o faʻaputuga photovoltaic lapopoa ma le tele-large-aperture. O le masini vili e faʻaaogaina ai le maualuga-torque rotary head design ma se faʻamau e oʻo atu i le 8000N/M e faʻamautinoa ai e fetaui ma manaʻoga o le Φ176-300-400mm galuega faʻapipiʻi la.
