The UZX-HW-910 is the smallest crawler DTH rig in the range, for rock drilling with 80–105 mm holes. The down-the-hole (DTH) hammer at the end of the rod strikes and rotates the bit directly in the rock, powered by compressed air from a separate compressor. The method is used in hard to very hard rock and through large boulders.
It has a 59 kW Yuchai engine, 980 N·m of torque, Ø60 × 2000 mm rods and a cylinder-and-chain feed. It weighs 3100 kg at 4100 × 2030 × 2020 mm and climbs 30° slopes. It has a two-stage dry dust collector and a rod changer. The UZX-HW-910-1 version, at 3260 kg, has dry dust collection.

The rig works with a down-the-hole (DTH) hammer: the pneumatic hammer goes down the hole with the bit, at the end of the rod string, and strikes the rock directly. No impact energy is lost along the rods, so the drilling speed stays almost the same at depth. The rotary head turns the string, the hydraulic cylinder with chain pushes it into the rock, and compressed air from the separate compressor carries the cuttings to the dust collector.
The two-stage dry dust collector keeps pollution low.
The rod changer shortens the time between holes.
At 3100 kg, it is easy to transport and move between small faces.
Suited to presplitting and production blast holes.
Blast holes in small quarries and rock excavation, contour presplitting, breaking large boulders and construction work in hard rock.
The UZX-HW-910 is the smallest DTH rig in the range, for 80–105 mm holes, at 3100 kg. For 90–152 mm holes choose the UZX-HW-920, and for 110–165 mm the UZX-HW-925 or UZX-HW-930. The rigs with an on-board compressor, UZX-HW-935 to UZX-HW-452H, work without a separate compressor.
The price depends on the version and the equipment: compressor, drill string, hammers and bits for your diameter. Send us the rock type, the hole diameter and depth and how many metres you drill per day, and a Uzinex engineer will prepare a quote for the right configuration. Delivery, commissioning and operator training are included in Romania.
• Delivery and commissioning included, at your site, with operator training.
• 60-month warranty, standard across the whole catalogue.
• Service with nationwide coverage in Romania, on-site visit within 24 hours.
• Spare parts in stock, so a breakdown does not stop the job.
• Technical documentation for EU-funded projects, PNRR and public tenders (SEAP/SICAP).
• Configuration on request: drill string, hammers and bits for your diameter and rock, the right compressor.

„We do stainless-steel metal fabrication dedicated to restaurant kitchens. The UZINEX equipment was a radical change: modernization, an increase in production and quality.”
„I had no idea, I was completely clueless. And you started to explain to me. You told me what technologies to choose, what packaging to produce, what would work better on the market.”
„We use a single person who can operate 3-4 machines. Before, we needed 3-4 people to do the same thing.”
„We have multiple challenges in making special structures that serve our systems, and the laser welding machine solution helped us enormously.”
„Laser welding on stainless is something else, it's a completely different thing. The quality of the machines is undeniable: the samples say it all.”
„With Uzinex, I felt very well protected by the assistance they provided. When you have a whole shift stalled and you need someone to answer quickly, it matters enormously.”
„The proof that everything went well is that the equipment now works. We have over three years of experience with no problems. Or when there were issues, there was support. We're satisfied with the collaboration.”
„I can do even 5 boxes for one person, I can also do 10 boxes. Which other firms can't do. That is, they'd have to change dies, set up a whole 12-hour affair.”
„Whether I called at 2 in the morning or at 9 in the morning, the problems got solved. We're satisfied and we'll work together again.”
„A good, smooth collaboration. We always had support and help.”
„We're among the top producers in Romania for this product. I wouldn't have imagined that when I started, but things fell into place.”
„On price and quality ratio, they were the best price and the best quality on the market. We got along well and we're satisfied.”
Six technology directions we integrate turnkey: from plug & play IIoT sensors, to cobots, predictive maintenance, optical inspection, MES connectivity and custom industrial software.
See in real time how much each machine produces and how long it sits idle. We fit sensors on any equipment, new or old, and within a few hours you have the OEE dashboard on your phone. No complex wiring, no production downtime. The first concrete step toward digitalization, with ROI visible from the very first month.
Solve your labor shortage without tripling your costs. The cobot works safely alongside your people (palletizing, feeding the CNC, welding) while you recover the investment in 12-18 months. Prices 30-40% below European distributors, with installation and programming included from us.
Stop waiting for things to break. Our algorithms analyze sensor data and tell you exactly which part will fail and when, and we bring it to your production line before the breakdown. Zero unplanned downtime, zero contractual penalties, complete operational peace of mind.
Eliminate defects before they reach the customer. Our cameras inspect every part at speeds no operator can match, detecting sub-millimeter defects. They mount onto your existing line, with no modifications. Ideal if you produce for export and have strict quality clauses.
Connect your machines to your office, regardless of brand or age. Our gateway automatically translates the data from any machine into your ERP's format: no manual entry, no paper forms, no human error. The manager sees production live, the operator receives digital instructions.
Have a process that no off-the-shelf software can solve? We build custom industrial applications: from tailored SCADA panels and HMI interfaces, to production planning systems, lot traceability and automated reporting. The code is yours, it runs on your servers, with no monthly subscriptions or vendor lock-in.
