Kaishan DTH Drilling Rigs
Heavy-duty surface crawlers and integrated rigs for open-pit mining, quarry blasting, and slope stabilization. High penetration rate and anti-jamming hydraulic system.
EQUIPMENT CATEGORIES
Powered by a single Cummins QSM15 77C diesel engine (563 kW), with a dual-end output design that simultaneously drives the onboard two-stage screw air compressor (39 m³/min at 25 bar) and the hydraulic transmission system for large-aperture 195–254 mm blast-hole drilling.
Features a precision aluminum guide rail (9550 mm feed stroke) for superior hole straightness and 2+1 semi-automatic handling of Φ140×9000 mm long drill rods to minimize rod-changing downtime, supported by floating joint thread protection, automatic oil injection lubrication, and electro-hydraulic anti-sticking control.
Governed by a high-sensitivity, labor-saving full-electric control system inside a certified FOPS & ROPS air-conditioned cab with real-time drilling angle and depth display, paired with a hydraulic cyclonic laminar-flow dry dust collector (with optional wet dust removal).

The Kaishan KD85 integrated surface DTH drilling rig is purpose-built for large-aperture bench blasting and pre-splitting operations across large-scale surface mines and heavy stonework projects:
The KD85 uses an extended 9550 mm aluminum guide rail and a 2+1 semi-automatic rod-handling system for heavy-duty Φ140×9000 mm drill rods, enabling 27 m of economical drilling depth with far fewer rod connections and superior hole straightness.
No. The KD85 integrates a high-capacity, two-stage screw air compressor that delivers 39 m³/min at 25 bar, powered directly by the 563 kW Cummins QSM15 77C diesel engine's dual-end output.
As an authorized China manufacturer and global B2B supplier, we provide factory-direct pricing, flexible MOQ, OEM/ODM customization, and complete genuine maintenance kits (k8/8″ DTH hammers, Φ140×9000 mm drill rods, and Cummins/air-end filters).
