HFPV solar drilling rig, using new type of hydraulic technology, convenient for hole transfer. The drillingmachine structure is compact,.while the mast has adjustable compensation function, when drilling, themast supported on the ground, borehole stability is good. The machine hydraulic pressure can be adjustedaccording to different soil textures, so as to achieve the appropriate impact power for pile driving, it is anewtype of pile driver. The drilling rig is mainly used in pile driving for photovoltaic Solar power station , pile driving for Highwayguardrail, highway guardrail construction engineering construction, etc.
