Solar Pile Drilling Rig HWL-390-H
Holes for solar piles, up to 400 mm with a down-the-hole hammer or up to 600 mm with an auger. The HWL-390-H drills 30 m deep and works on slopes up to 45 degrees.
The rig works either with a down-the-hole hammer or with an auger. The hammer drills 76 to 400 mm, the auger 600 mm, both to a depth of 30 metres. The catalogue states rock hardness of 6 to 20 F and an air consumption of 10 to 36 m³ per minute.
Mast and boom both swing, the mast by 40 degrees in total and the boom by 50 degrees. The crawler undercarriage works on slopes up to 45 degrees and can extend one side by up to 1,200 mm. Rated power is 85 kW and the weight 7,410 kg.
