CE Certified DTH Drilling Machine with 115-178mm Diameter Range and 1.7-2.5MPa Working Pressure

We've had quarry operators come back to us after running this through granite and they basically said the 92KW engine pulls its weight better than anything in this class they'd tried before, though the 60m depth limit means you're not taking it into deep well work—that's just the reality of a 9700kg machine designed for suface-level production.

Working pressure sits at 1.7-2.5MPa which gives you decent penetration in medium-hard rock, and the 3300N.m rotation torque at 0-80rpm handles the 115-178mm diameter range without bogging down, but the feed stroke is 3000mm so you're cycling rods every three meters (the automatic change kicks in at 18m depth, saving some sweat on the 5+1 pipe setup).

Most buyers are using 89×3000mm drill pipe with this, and the 360L fuel tank keeps you running a full shift or so before refueling, but it's not ideal for tight urban corners—the 8610mm overall length can be a pain in constrained sites, though the 2210mm width is manageable for most access roads.

Actually, the automatic rod changer is what buyers ask about most, and it works well within teh 60m envelope, but you're still handling the first two rods manually (roughly 18m) before the automation takes over.

We usually stock these, so lead time is about 20 days or so, and bulk pricing on 3+ units drops roughly 8-10% depending on your dilevery terms—just confirm the CE and ISO 9001:2015 certs are current for your region.

One year engine and hydraulics, but the hammer and drill bits are on you—that's standard for this class of gear anyway.
