DUD125 is a compact underground drill rig for development faces where roadway width, turning space and machine mobility are key selection factors. It combines a telescopic parallel boom, aluminium feed, hydraulic rock drill and articulated four-wheel-drive carrier in a 1.3 m-wide machine.
The rig provides up to 24 m² drilling coverage and supports face blast-hole and compatible bolt-hole drilling. Typical applications include underground mines, small tunnels, hydropower construction, inclined shafts and culverts.
The published machine width is 1,300 mm. This narrow profile, combined with articulated steering and a 2,504 / 4,463 mm turning radius, helps the rig move through confined underground access routes.
The single parallel boom provides up to 24 m² coverage, or approximately 5,025 × 5,000 mm. A 1,500 mm boom extension, +52°/-43° lift and ±30° swing support positioning across the development face.
Published feed lengths are 4,740 and 5,400 mm, matched with 3,090 and 3,700 mm drill steel. The corresponding published hole depths are 2,830 and 3,440 mm, allowing the drilling package to be selected for the required round.
The current page lists Epiroc 18U and Montabert HC109 hydraulic rock drill options. Confirm the selected drifter, drill steel, bit diameter and corresponding performance data in the technical proposal.
The three-pump hydraulic system separates key functions to support stable flow. Anti-jamming, anti-idle percussion and automatic retraction functions help the operator respond to changing drilling resistance and limit unnecessary loading on drill tools.
Four-wheel drive, hydrostatic transmission, ±40° articulated steering and 20° published gradeability support travel on narrow or inclined underground routes. Tramming speed is listed at up to 10 km/h.
Before ordering, confirm the feed length, required hole diameter and depth, rock drill, drill steel and local electrical standard. The page lists 380 V/50 Hz as standard and 440 V/60 Hz as an alternative. An extended front axle and air hole-blowing function are listed as optional; availability should be confirmed in the quotation.
Safety devices, guarding, certification and emergency equipment must be confirmed for the destination market and mine standard.

It is a compact single-boom underground face drill jumbo for development blast holes and compatible bolt holes in narrow mine roadways, small tunnels and other confined headings.
The published machine width is 1,300 mm. The complete access route, turning space, transport height and working envelope should still be checked against the project drawing.
The published maximum coverage is 24 m², or approximately 5,025 × 5,000 mm.
The page lists two configurations with published hole depths of 2,830 and 3,440 mm. Actual drilling performance depends on the selected feed, rock drill, drill tools, rock condition and hole plan.
The current page lists Epiroc 18U and Montabert HC109 options. Confirm the selected model and its matching performance data in the final quotation.
Send the roadway width and height, required hole diameter and depth, drilling pattern, rock condition, site voltage and frequency, water supply, access gradient, destination country, quantity and required options.
