Product Overview
The KT 15C Integrated Down The Hole Drill Rig For Open Use delivers the complete hexa-engine power architecture, ultra-high-capacity compressor system, and maximum-class drilling performance of the KT 15 series in an open-station canopy configuration, purpose-designed for operations where the KT 15's enclosed cabin is not required by site regulations or operating context, and where capital cost efficiency is a primary procurement consideration alongside maximum drilling performance. Sharing the same six-engine architecture, 90 to 130 m3/min compressor output, 381 to 445 mm hole diameter range, 72 m maximum depth, and full intelligent control suite as the KT 15, the KT 15C provides identical drilling output at a lower acquisition cost and reduced operating weight, making it the preferred choice for experienced operators in environments where open-station operation is standard practice and enclosed cabin requirements do not apply.
Like the KT 15, the KT 15C is a bespoke engineering program. Each unit is configured to the specific geological, operational, and regulatory requirements of the customer's project. The open-station configuration does not reduce the machine's drilling capability, compressor specification, autonomous operation level, digital twin system, or intelligent control suite in any respect - it delivers every performance advantage of the KT 15 platform at a lower capital cost and approximately 2,500 to 3,000 kg less operating weight, with the ROPS-rated canopy providing certified overhead protection that meets the operator protection requirements of the majority of mining and quarrying regulatory frameworks worldwide.
For contractors and mine operators who require the absolute maximum in integrated DTH drilling capacity and autonomous intelligence, but whose operating context permits open-station operation, the KT 15C is the most cost-efficient path to KT 15 series performance.

- Cost-optimised flagship deployments: operations where the KT 15 series' maximum drilling capacity and autonomous intelligence are required, but where the enclosed cabin's capital cost premium is not justified by the operating context, making the KT 15C the more commercially efficient choice.
Frequently Asked Questions
Q: What is the difference between the KT 15C and the KT 15, and how do I choose between them?
A: The KT 15C and KT 15 are mechanically and electronically identical in every respect that affects drilling performance, autonomous operation, and intelligent control: same hexa-engine architecture, same compressor specification (90 to 130 m3/min, up to 60 bar), same hole diameter range (381 to 445 mm), same maximum depth (72 m), same rotary torque (16,000 N.m), same Level 4 autonomous drilling, same digital twin system, same triple-carousel rod handling, same quad-axis anti-deviation, same 25-parameter data logging, and same AI-driven predictive maintenance. The sole difference is the operator station: the KT 15C features an open platform with a ROPS-rated canopy, while the KT 15 is equipped with a fully enclosed ROPS/FOPS certified cabin with quad-zone climate control, HEPA-grade dust filtration, acoustic insulation below 65 dB(A), and a full-width curved immersive display. Choose the KT 15 when site regulations mandate enclosed operator protection, when climate conditions require a controlled cabin environment, or when RCS dust exposure compliance requires cabin-level filtration. Choose the KT 15C when those requirements do not apply and capital cost efficiency is the priority - you receive identical drilling and autonomous performance at lower cost and approximately 2,500 to 3,000 kg less operating weight.
Q: Does the open-station configuration affect the KT 15C's autonomous drilling capability?
A: No. The KT 15C's Level 4 autonomous drilling capability is entirely independent of the operator station configuration. The autonomous control system, digital twin, sensor array, GPS navigation, 5G and satellite communication, and all intelligent control features are powered by the dedicated quinary and senary engines and operate identically on the KT 15C and the KT 15. In full autonomous mode, the operator station is not in use - the machine operates without on-site personnel - so the distinction between open and enclosed station is irrelevant to autonomous operation. The KT 15C is fully capable of executing complete autonomous drilling programs, including GPS-guided tramming, automatic setup, digital-twin-optimized drilling, automated rod handling, and autonomous repositioning, without any operator intervention.
Q: What operator protection does the ROPS canopy provide on a machine of this size and weight?
A: The ROPS (Roll-Over Protective Structure) canopy on the KT 15C is independently certified to protect the operator in the event of machine roll-over, meeting the structural integrity requirements of international construction and mining equipment safety standards for mobile plant at this weight class. The canopy is engineered to the KT 15C's operating weight of approximately 92,000 kg, with structural calculations and certification specific to this machine. It also provides overhead protection from falling objects at the level specified by the canopy's FOPS rating. The ROPS canopy is the standard operator protection configuration for open-station drilling rigs in many mining and quarrying jurisdictions worldwide and is accepted as compliant with national safety regulations in the majority of markets where open-station operation is permitted.
Q: Can the KT 15C be upgraded to an enclosed cabin configuration after delivery?
A: The KT 15C and KT 15 share the same base machine platform, and the cabin mounting structure is designed to accommodate both operator station configurations. Field conversion from open to enclosed cabin is technically possible but requires factory-supplied cabin assembly, mounting hardware, HVAC components, and updated ROPS/FOPS certification, and must be carried out by a qualified service team. Customers who anticipate a future requirement for an enclosed cabin are strongly advised to order the KT 15 from the outset, as the total cost of a field conversion typically exceeds the price difference between the two models at the time of initial purchase, and the conversion requires a significant machine downtime period.
Q: How does the digital twin system function on the KT 15C?
A: The digital twin system on the KT 15C is identical to that on the KT 15: a real-time physics-based computational model of the machine's drill string, DTH hammer, drill bit, and surrounding rock formation, powered by the dedicated senary engine and updated continuously from 25 sensors at 10 Hz sampling rate. It calculates the theoretically optimal drilling parameters at every 0.05 m depth increment and commands the drilling system to execute them automatically, tracks cumulative bit wear in real time, predicts formation boundaries ahead of the current drill depth, and synchronizes with the fleet-wide learning network via satellite. The open-station configuration has no effect on the digital twin system's operation or capability.
Q: What are the transportation and mobilization requirements for the KT 15C?
A: With an operating weight of approximately 92,000 kg, the KT 15C requires a specialized multi-axle heavy-haul trailer rated for 100 tonnes or above; special transport permits and route surveys will be required in all markets. The KT 15C is approximately 2,500 to 3,000 kg lighter than the KT 15 due to the absence of the enclosed cabin assembly, which may reduce transport axle loading requirements marginally in some markets. For international export, the machine is shipped as heavy break-bulk cargo on a specialized heavy-lift vessel or on multiple flat-rack units, with full export documentation and a dedicated logistics coordination service provided. On-site, the rig self-trams between drilling positions at up to 1.2 km/h using GPS-guided autonomous navigation.
Q: Is the KT 15C also a bespoke engineering program like the KT 15?
A: Yes. Like the KT 15, the KT 15C is a bespoke engineering program. Each unit is configured to the specific geological, operational, and regulatory requirements of the customer's project, including the compressor specification, engine configuration, digital twin formation model initialization, autonomous control system programming, 5G and satellite communication integration, and operator station configuration. The procurement process begins with a dedicated project engineering consultation between the customer's technical team and our senior project engineers. Contact our senior project team to initiate the process.
Q: What after-sales support and service infrastructure do you provide for KT 15C deployments?
A: KT 15C deployments receive the same platinum-tier project support package as the KT 15: a dedicated senior project engineering team assigned from contract signature through project completion, on-site commissioning and comprehensive operator and maintenance training, a permanent resident service engineer for the duration of the drilling program, a dedicated on-site spare parts depot with a full-time logistics manager, and a direct 24-hour hotline to our factory engineering and digital twin development teams. The digital twin system provides our service team with the most detailed real-time machine health data available from any drilling machine, enabling predictive maintenance interventions weeks before faults develop. For multi-fleet deployments, a dedicated global support coordination center is established for the project.
