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 heavy-duty Cummins QSZ13-500-30 diesel engine (372 kW), with a two-terminal output configuration that simultaneously drives the two-stage screw air compressor (31 m³/min at 25 bar) and the hydraulic transmission system for high-penetration 152–203 mm blast hole drilling.
Equipped with an automatic rod-handling system (6+1 for 5000 mm rods or 5+1 for 6000 mm rods), a floating-joint module to protect drill-pipe threads, automatic oil-injection lubrication, and electro-hydraulic anti-sticking control for continuous 35 m/36 m deep-hole production.
Features a certified FOPS & ROPS air-conditioned safety cab with real-time drilling angle and depth display, paired with a hydraulic cyclonic laminar-flow dry dust removal system (with optional wet dust suppression) for safe, eco-friendly open-pit operations.

The Kaishan KD70 integrated surface DTH drilling rig is engineered for large-scale bench blasting and pre-splitting operations across heavy surface mining and civil infrastructure projects:
The KD70 supports two automatic rod handling configurations for 5" and 6" DTH hammers: a 6+1 carousel using Φ102/Φ114/Φ127×5000 mm rods (5700 mm feed stroke, 35 m economical depth) or a 5+1 carousel using Φ102/Φ114/Φ127×6000 mm rods (6700 mm feed stroke, 36 m economical depth).
No. The KD70 integrates an onboard two-stage screw air compressor that delivers 31 m³/min at 25 bar, powered directly by the 372 kW Cummins QSZ13-500-30 diesel engine's two-terminal 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 (5"/6" DTH hammers, Φ102/Φ114/Φ127 drill rods, and Cummins/air-end filters).
