The Emergency Rescue Hydraulic Drilling Rig DH190 is a heavy duty full hydraulic crawler mounted multi purpose drilling rig designed in accordance with ISO construction machinery standards, oriented to disaster emergency rescue, tunnel disaster relief, geotechnical reinforcement and complex underground engineering operations.
The Emergency Rescue Hydraulic Drilling Rig DH190 is a heavy duty full hydraulic crawler mounted multi purpose drilling rig designed in accordance with ISO construction machinery standards, oriented to disaster emergency rescue, tunnel disaster relief, geotechnical reinforcement and complex underground engineering operations. Equipped with high torque impact rotary power head, wide track reinforced crawler chassis and multi angle luffing drilling mast, this rig integrates wired handle and wireless remote control dual operating modes, adapting to narrow disaster site spaces and complex broken rock working conditions. It supports DTH air percussion drilling, mud rotary drilling, casing follow up drilling and grouting hole construction processes, and can implement vertical, horizontal and inclined multi azimuth borehole operations. Built in anti stuck drilling impact pipe pulling mechanism effectively copes with collapse prone broken strata in emergency rescue scenarios. Featuring strong cross country passability, compact overall dimension and rapid on site deployment capability, DH190 delivers reliable drilling performance for landslide rescue, tunnel collapse relief, slope reinforcement and urban emergency geotechnical projects for global emergency rescue teams and engineering contractors.
Integrated rotary impact composite output realizes efficient drilling in hard rock and fractured broken strata. Independent high frequency impact pipe pulling module provides powerful casing extracting capacity, effectively solving drill pipe jamming risks frequently occurring in collapse prone emergency rescue sites, improving continuous construction reliability under harsh geological conditions.
Wireless remote control enables operators to operate away from rock fall hazard zones during rescue missions; wired handle serves as backup control mode to guarantee normal operation under strong signal interference complex disaster site environment. Real time pressure and torque feedback helps operators judge underground stratum variation in time.
The drilling mast supports large amplitude swing, pitching and luffing adjustment, freely realizing horizontal, inclined and vertical drilling. Built in feed compensation stroke offsets on site assembly position deviation, shortens repeated positioning time for each borehole and improves rescue mission response efficiency.
Advanced load sensing variable hydraulic pump group dynamically distributes flow and pressure according to actual drilling load, achieving adaptive power matching for different working conditions, reducing unnecessary energy consumption. Multi stage over pressure protection and pipeline burst resistance protection enhance equipment safety under impact load rescue site operation.
Widened anti sink track shoes lower ground specific pressure for stable travelling on muddy, debris covered disaster sites. Independent hydraulic travel motors realize flexible in situ steering and short distance relocation, adapting to rugged, unimproved rescue site terrain with limited passage space.
Integrated compact structural layout satisfies transportation and operation requirements of narrow disaster relief passages. Key hydraulic components and wearing parts adopt universal industrial specifications, facilitating rapid spare parts replacement and emergency field repair under remote disaster site conditions.

Landslide debris, tunnel collapse and urban grouting sites share one nasty constant: broken, collapse-prone ground where the drill string jams and casing must follow the hole down. Is your current unit built to pull that string back out? The DH190 emergency rescue hydraulic drilling rig is engineered for exactly that failure mode — a 9200 N·m impact-rotary power head at 30-75 r/min, an independent high-frequency impact pipe-pulling module, and 100 kN feed over 100 kN lift, covering 110-320 mm holes at 30-190 m. Its 360° mast drills vertical, horizontal and inclined bores, and load-sensing hydraulics match flow to load through gravel soil, fractured rock and weathered hard ground.
Before requesting a DH190 quotation, the configuration questions are mission-specific: the azimuth range your bores must cover — the multi-angle mast handles horizontal through vertical, but the rod choice between 76, 89 and 102 mm pipes changes string stiffness — the casing-follow-up and anti-jamming duty in collapse zones, and whether the site sits underground where exhaust is restricted, in which case an electric or hybrid drive with explosion-proof components serves confined mine relief. State your debris conditions and passage width, because the widened anti-sink tracks and 7800 x 2480 mm shipping footprint are chosen against access. The rig runs -20 °C to +50 °C; the wireless remote keeps operators clear of the fall line while the wired handle covers signal-poor disaster sites.
Each DH190 shipped from our Jingzhou plant carries the complete export paperwork for customs, plus the impact pipe-pulling tooling and spares your contract demands. Because each unit is configured around hole azimuth, casing duty and power source, the quotation is assembled from your hole plan instead of lifted from a price sheet.
Adjust power head torque speed and impact frequency parameters for ultra hard rock or heavily broken collapse prone strata; match heavy diameter casing follow up assembly for emergency rescue borehole construction.
Optional full electric drive or hybrid power configuration for underground enclosed disaster relief sites with strict exhaust emission limits; match explosion proof electrical components for mine emergency rescue environment.
Optional ultra wide anti sink crawler tracks for swampy and soft mud disaster sites; optimize overall dimension for extra narrow mountain road transportation condition.
Auxiliary high pressure grouting manifold, real time drilling depth recording module, anti dust enclosure assembly and enhanced long distance wireless remote control module are optional for complex rescue site requirements.
