Product Overview
Model: YTR-Doosan | Category: Foundation Construction Equipment
The Rotary Blasthole Drilling Rig (Doosan Chassis) is purpose-built for open-pit mining and quarry blasthole drilling operations. Mounted on a heavy-duty truck chassis (Caterpillar or Doosan option), this hydraulic drilling rig delivers rapid hole penetration with precise depth control, making it ideal for large-scale mining projects requiring consistent borehole quality across granite, limestone, and overburden layers.

Mobility
1. Agile Doosan Chassis
The Doosan heavy-duty truck chassis keeps the blasthole rig mobile between benches but at a lighter overall weight and tighter turning circle. It suits smaller quarries and satellite pits where a full-class mining drill would be overkill and hard to manoeuvre.
2. Balanced Rotary Power
The hydraulic rotary head delivers the torque needed for limestone and weathered rock while staying fuel-efficient on shorter shifts. Variable RPM and crowd feed keep the bit in the ground through changes in strata.
3. Compact Footprint
The lighter chassis and mast package fit narrower bench roads and smaller quarry layouts, making it practical for contractors moving from one small pit to the next rather than running a single large operation.
4. Cost-Effective Ownership
Lower capital price, simpler service and proven Doosan powertrain components make this the value option for mid-sized producers who need genuine blasthole capacity without a full-class mining rig.
Technical Parameters
About the Rotary Blasthole Drilling Rig (Doosan Chassis)
The Doosan-chassis blasthole rig is the agile choice for small-to-medium quarries and satellite mine pits. It blasthole-drills limestone, sandstone and overburden on sites where bench roads are narrow and the machine moves often between faces.
Because it is lighter than a full mining-class rig, it accesses quarries with restricted site space and lower ground-bearing capacity, and it relocatse quickly between small pits—ideal for contract drilling crews serving several customers.
Yutong offers this chassis option for producers who want real blasthole performance at a lower entry price. It is a common specification in smaller quarries across Africa, the Middle East and Southeast Asia where a CAT-class machine would be under-utilised.
The Doosan chassis option is a popular choice for smaller quarries looking to enter blasthole drilling without a full mining investment. Yutong provides operator training and a recommended spares kit so the crew becomes productive within the first project.
The Doosan chassis option is popular with contract drilling crews that move between small quarries; Yutong configures the mast and dust package to the hole diameter you drill most often, and ships a starter spares kit with each machine.
Operators in smaller quarries value the Doosan rig for its simple maintenance and lower entry cost; it trams quickly between faces, and the dust-controlled cab keeps the crew productive through a full drilling shift.
Tell us your typical hole diameter, depth and rock type and Yutong will confirm the Doosan-chassis configuration and a delivery schedule for your first project.

View DetailsWhat size quarry is the Doosan rig best for?
It suits small-to-medium quarries and satellite pits with narrow bench roads and frequent relocation; it is the value option below a full-class mining drill.
How does it differ from the CAT-chassis model?
The Doosan chassis is lighter, more agile and lower-cost, while the CAT chassis is the heavier, globally supported mining platform. Choose by site size and your existing service network.
Can it handle granite?
It handles limestone, sandstone and weathered granite well; for hard, abrasive granite on large benches the higher-torque YTR rotary rigs are the better match.
Is it easy to transport between sites?
Yes—its lighter weight and wheeled chassis make road relocation between small pits straightforward for a contract drilling crew.
What hole depths can it reach?
Mast and rod configuration are matched to your bench height; tell us the required depth and the team will specify the feed and rod count.
What after-sales support is included?
Yutong supplies parts, operator training and remote technical support, and the Doosan powertrain is supported through the regional Doosan network.
