The DALI DUB135 is an underground rock bolting rig for mechanized roof, sidewall and lock-foot support in non-explosive mine environments. It integrates bolt-hole drilling, resin cartridge conveying and bolt installation, with published bolt lengths from 1,800 to 2,500 mm. A telescopic boom, three-position bolting head and compact articulated carrier support work across different roadway sections.

DUB135 is a mechanized underground bolter designed to combine drilling and bolt installation on one carrier. The bolting unit integrates hole drilling, resin cartridge delivery and bolt installation, reducing the need to move separate machines between these steps.
The rig is intended for systematic roof bolts, side bolts and lock-foot bolts in underground mine roadways described by the source as non-explosive environments. Its published working envelope ranges from 3.5 × 3.5 m to 8.8 × 7.1 m. Resin bolts and pipe-seam friction bolts are listed as applicable bolt types.
The bolting device combines bolt-hole drilling, resin cartridge conveying and bolt installation. This gives the operator one mechanized workflow for the main bolting steps and simplifies equipment coordination at the heading.
Montabert HC25, HC28 and HC50 rock drills are listed for different hole and bolt requirements. The selected rock drill must be matched with bolt length, drill steel, hole diameter, roadway height and bolting-device length.
Published bolt lengths range from 1,800 to 2,500 mm. The available lengths and corresponding drill depths differ by HC25, HC28 or HC50 bolting-head configuration, allowing the machine to be specified around the mine’s support design.
The single boom provides 1,500 mm feed-compensation extension, +65°/-30° lift and ±40° swing. These movements help position the bolting head for roof, sidewall and lock-foot holes across the roadway section.
Three independent pumps control the hydraulic drilling system. Anti-jamming, anti-idle percussion and automatic retraction functions help the operator respond to changing drilling resistance and limit unnecessary loading on drilling tools.
An optional mesh grab manipulator is listed for handling mesh weighing up to 50 kg. Required roadway height increases when the mesh handler is installed, so the selected bolting package and heading dimensions must be checked together.
The carrier uses four-wheel hydraulic drive and different front/rear track widths to support turning stability and access through narrower roadways. Published gradeability is 15°, with at least 260 mm ground clearance.
Before ordering, confirm the ground-support design rather than selecting by machine model alone. Provide the bolt type, bolt length, required hole diameter and depth, resin cartridge diameter, bolt pattern, roadway profile, rock condition and whether mesh handling is required.
Also confirm the available 380 V/50 Hz electrical supply, minimum 2 bar water inlet pressure, access route, turning space and destination-market safety requirements. The current page states that the DUB135 is for non-explosive environments; suitability for coal mines, gassy mines or hazardous atmospheres must not be assumed.
Published safety features do not establish explosion protection or compliance with a destination market. Required guarding, emergency systems, operator protection, fire suppression and certifications must be confirmed before quotation and use.
