Epiroc surface drill rig boring blast holes on a quarry bench

Drill Rigs & Rock Drills for Mining and Civil Excavation

Surface drill rig → underground jumbo → hydraulic breaker — engineered as one excavation chain, commissioned by our field team and supported from regional rock-tool hubs.

Engineering Choices That Keep Drill Fleets Productive

Four systems equipment managers audit before awarding a multi-year drill-rig frame agreement.

Hydraulic rock drill on boom with visible feed rails

Hydraulic percussion with stable torque curves

Epiroc rock drills hold percussion frequency and torque within tight bands so bit life stays predictable when UCS jumps between benches. Controllers log feed-force spikes that usually precede stuck rods, giving supervisors a chance to pull before a round stalls.

Tier 4 Final engine bay on surface drill rig

Tier 4 Final / Stage V without derating the compressor

Aftertreatment packages are sized so flushing air does not collapse when DPF regeneration starts mid-bench. Electric trolley variants cut underground ventilation load while keeping the same feed and rotation envelopes used on diesel sisters.

Drill rig undercarriage on rough quarry haul road

Undercarriage built for tramming between benches

Track frames, idlers and oscillation joints are selected for short trams over blasted rock rather than paved yards. Grease points sit where a single oiler can reach them without scaffolding, cutting the minutes lost at every pad move.

Regional parts hub shelving rock drill consumables

Global parts supply with rock-tool kits staged regionally

Bits, rods, shank adapters and breaker chisels ship from regional hubs that also stock hydraulic pumps and feed cylinders. Contracted MTTR targets keep development headings and quarry benches from waiting on air freight for common failure modes.

Procurement & Service Questions We Hear Weekly

Procurement & Logistics

What is typical lead time for a surface drill rig?
Standard configurations ship in 14–22 weeks depending on compressor class and cabin options; expedited slots open when a regional buffer unit matches your hole-diameter envelope.
Which Incoterms and packing options are available?
FOB, CIF and DAP are routine. Rigs leave with seaworthy cradles, moisture barriers and a commissioning crate that includes first-fill lubricants and bit starter kits.
How do you document CE and EPA Tier 4 Final compliance?
Each serial number ships with a Declaration of Conformity, engine emission family data and a noise dossier suitable for site HSE files.
Can underground packages meet ATEX expectations?
Selected jumbo and face-drill packages are available with hazardous-area electrical and lighting kits; we confirm zone assumptions before freezing the BOM.

Service & Spare Parts

What MTTR should we expect on contracted sites?
Priority sites target under 18 hours for common hydraulic and rock-drill failures when consumables are stocked locally under the parts rider.
How often should rock-drill seals and chucks be planned?
Most hard-rock fleets schedule seal kits every 800–1,200 percussion hours; we align the interval to your UCS and flush quality, not a generic calendar.
Do you support excavator-mounted hydraulic breakers?
Yes — hydraulic breaker for excavator packages include tool kits, nitrogen charge procedures and carrier oil-flow matching sheets.
Who trains operators after commissioning?
Field instructors cover collaring technique, anti-jam recovery and daily ISO cleanliness checks before handing the shift to your trainers.
