DUD135 is an underground drill rig designed for development faces where maneuverability, drilling coverage and straightforward maintenance are important. The rig combines a single parallel boom, aluminium feed, hydraulic rock drill and articulated four-wheel-drive carrier in one compact jumbo drill machine.
It is intended for headings from approximately 3.5 × 3.5 m and provides a published maximum coverage area of 35 m². Typical work includes face blast-hole drilling and compatible bolt-hole drilling in underground mines, hydropower projects, small tunnels, inclined shafts and culverts.
The parallel boom provides up to 35 m² coverage, with 1,250 mm boom extension, +65°/-30° lift and ±40° swing. This helps the operator position the feed across the face without repeatedly moving the carrier.
The 5,990 mm aluminium feed accepts 4,305 mm drill steel and delivers a published hole depth of 4,000 mm. Its ±180° roll-over supports flexible hole positioning for development rounds.
The DUD135 can be configured with an Epiroc 18U or Montabert HC109 hydraulic rock drill. Confirm the preferred drifter, drill steel and bit combination when requesting a technical proposal.
The three-pump hydraulic system separates key functions to support stable flow. Anti-jamming, anti-idle percussion and automatic retraction functions help respond to changing drilling resistance and reduce unnecessary drill-tool loading.
Four-wheel drive, articulated ±45° steering, up to 16 km/h tramming speed and at least 260 mm ground clearance help the rig travel and turn in underground access routes. The published gradeability is 14°.
The full-coverage hood protects the power, transmission, hydraulic and electrical systems. A single-layer hose arrangement, accessible components and fault/protection functions support routine inspection and maintenance.
Before ordering, confirm the required rock drill, drill steel, bit diameter, hole pattern and local power standard. The published electrical options include 380 V/50 Hz, 440 V/60 Hz, 480 V/60 Hz, 550 V/50 Hz and 660 V/50 Hz. Final supply voltage, connector, cable and compliance package should be agreed in the quotation.
Safety devices, guarding, certification and emergency equipment must be confirmed for the destination market and mine standard.

It is a single-boom underground face drill jumbo for development blast holes and compatible bolt holes in mines, tunnels and other confined underground headings.
The published maximum coverage is 35 m², or approximately 6,600 × 6,630 mm. The current product page also lists headings starting from about 3.5 × 3.5 m; the access route and actual drilling envelope should be checked against the project drawing.
The published hole depth is 4,000 mm with 4,305 mm drill steel. Actual drilling performance depends on the selected rock drill, drill tools, rock condition and hole plan.
The page lists Epiroc 18U and Montabert HC109 options. Confirm the required model and its corresponding performance data in the final quotation.
Send the heading width and height, required hole diameter and depth, drilling pattern, rock condition, site voltage and frequency, water supply, destination country, quantity and required safety options.
