Launched the revolutionary 420GF photovoltaic drilling rig, the ultimate solution for large-slope mountain operations. The solar piling machine is equipped with a spreader as standard, which is the best choice for installing large-aperture and ultra-large-aperture photovoltaic piles. The drilling rig adopts a high-torque rotary head design with a torque of up to 8000N/M to ensure that it meets the needs of Φ176-300-400mm solar piling operations.
