JK590BC Crawler Mounted Hydraulic DTH Drill Rig

JK590BC is a crawler mounted hydraulic DTH drill rig developed for surface blast hole drilling in open-pit mines, quarries, hydropower projects and road construction sites. It is designed for contractors that need a practical and stable drilling solution for repeated bench drilling, rock excavation and production blasting operations.

With a 90–165 mm borehole diameter range, a maximum drilling depth of 50 m and a long 4138 mm feeding stroke, JK590BC is suitable for medium-diameter blast holes in medium-hard to hard rock formations. The rig combines hydraulic travelling, feeding, lifting, rotation and positioning functions with DTH hammer drilling, helping operators maintain efficient drilling performance across changing bench conditions.

Rather than serving as a deep water-well or exploration drilling machine, JK590BC is primarily built for surface drilling work where drilling efficiency, equipment mobility, air compressor matching and cost per drilled meter are important.

JK590BC Crawler Mounted Hydraulic DTH Drill Rig Parameters

The main parameters of JK590BC crawler mounted hydraulic DTH drill rig are:

Designed for Surface Blast Hole Operations

JK590BC is a suitable choice for projects requiring regular blast hole drilling in exposed rock formations. Typical applications include:

• Open-pit mine bench drilling

• Quarry blasting and aggregate production

• Hydropower project rock excavation

• Highway and road cutting projects

• Railway, tunnel portal and slope excavation work

• Infrastructure construction requiring controlled rock blasting

• National defense and remote-area construction projects

For deep water wells, mud circulation drilling or more complex geological drilling conditions, please refer to our Crawler Mounted Versatile Well Drilling Rig.

Built for Continuous Bench Drilling

Long Feeding Stroke for Productive Drilling Cycles

The 4138 mm feeding stroke supports stable drilling progress with 3 m drill rods. This configuration is suitable for contractors that need to complete repeated drilling cycles across quarry benches or open-pit mine working faces.

Reliable Torque for Hard Rock Conditions

With a rotation torque of 3000 Nm and a rotation speed of 0–80 rpm, JK590BC is designed to support DTH drilling in rock hardness from f=6 to f=20. The rig can be matched with suitable DTH hammers, drill rods and drill bits according to the required hole diameter and site geology.

Crawler Mobility for Rough Job Sites

The crawler undercarriage helps the rig move between drilling positions on uneven benches, loose ground and rugged construction areas. With travel speeds of 2–3 km/h and gradeability up to 24°, JK590BC is suitable for surface projects where stable movement between blast-hole locations is required.

Flexible Power Selection

JK590BC can be supplied with different power options to suit local fuel availability, service preferences and site power conditions:

• Yuchai 70 kW diesel engine

• Cummins 74 kW diesel engine

• 45 kW electric motor

The diesel version is suitable for mobile mine, quarry and construction sites. The electric motor version can be considered for fixed work areas with stable electricity supply.

Main Applications of JK590BC Crawler Drilling Rig

JK590BC crawler mounted hydraulic DTH drill rig is mainly used for:

• Hydro‑power engineering drilling and hydropower project blasthole drilling

• Open pit mining drilling and blasting, open‑pit mine bench drilling

• Quarry drilling rig operations for bench blasting and aggregate production

• Road construction drilling and blasting for highways and tunnels

• Drilling and blasting operation of national defense engineering and military projects

• Water well drilling and geothermal well drilling with large borehole diameter and shallow to medium depth

With a borehole diameter range of 90–165 mm and drilling depth up to 50 m, this hydraulic crawler drilling rig can cover most surface DTH drilling applications that require efficient and economical drilling.Get a quote.

Air Compressor Matching for JK590BC

Proper air supply is essential for DTH drilling performance. JK590BC operates with working air pressure from 1.2 to 2.4 MPa and air consumption from 11 to 21 m³/min.

The final air compressor selection should be based on:

• Required hole diameter

• Rock hardness and drilling depth

• DTH hammer size

• Expected drilling hours per shift

• Site altitude and ambient temperature

• Required drilling speed

• Dust control configuration

For standard quarry and mining projects, JK Drilling can recommend a matched air compressor together with the rig. View our Air Compressor range or contact us with your drilling conditions for a complete package recommendation.

Why Choose JK590BC DTH Drilling Machine?

• Superior Penetration Rate: Equipped with a high-power hydraulic system, the JK590BC ensures fast penetration speeds in hard rock formations, significantly reducing your project timeline.

• Crawler Mounted Mobility: The heavy-duty crawler undercarriage provides excellent stability and maneuverability on uneven construction sites and mountainous areas, distinguishing it from truck-mounted alternatives.

• Versatile Application Range: This multi-purpose drilling rig is adaptable for various hole diameters (90mm-140mm) and depths up to 200 meters, perfect for water wells, mining exploration, and anchoring projects.

• Energy Efficiency & Low Maintenance: Optimized hydraulic circuit design reduces fuel consumption, offering a cost-effective solution for long-term drilling operations.

• Operator Comfort: Features a spacious, insulated operator cabin with excellent visibility, reducing fatigue during long shifts.
