Inquiry
If you're running a quarry and need to punch 260-300 meter blast holes through hard rock day after day, HQZ series is pretty much what most operators end up on — we've shipped dozens to guys who were burning through smaller rigs every 18 months.
The 260L weighs in at 6.4 tons with a 1.9-meter-wide track, which is tight enough for narrow bench access, and it'll drill 140-300mm holes at 20-40 meters per hour using a 76/89mm pipe string — but teh 300L bumps torque up to 10,000 Nm and adds a 6-meter advance length option for faster cycle times on deeper holes.
It's not a soft-ground machine — the impactor hammer system is designed for sandstone, granite, and cobblestone, so if you're drilling clay or loose overburden you'll want to switch bits or look at a rotary unit. One thing nobody tells you is the 30-degree climb angle is fine on packed gravel but gets dicey on wet mud, so keep that in mind for site layout.
For ordering, we usually have the 260L in stock (roughly 6-8 weeks lead time if we don't), and the MOQ is one unit with a 30% deposit to lock production — just send over your preferred diesel or electric motor choice and we'll confirm specs.
The HQZ-260L weighs 6.4T and has a drilling diameter of 140-300 mm, while the HQZ-300L is heavier at 8T with a diameter up to 325 mm. The 300L also offers higher rotation speed and torque, plus a one-time advance length of up to 6000 mm versus 3000 mm on the 260L.
Yes, the rig is CE and ISO 9001:2000 certified. We include copies of both certifications with every shipment.
You can choose from 1.5 m, 2.0 m, or 3.0 m drill pipe lengths. Just let us know your preference when ordering.
Our MOQ is 1 unit. We can ship a single rig directly to your site.
We package it in a sturdy wooden crate or steel frame, with all loose parts strapped and wrapped for moisture protection. Store it in a dry, covered area if not used immediately.
