How deep can a crawler core drill rig drill? (YDX-1000 / YDX-1800 depth capacity)
Depth capacity is the first number buyers ask for in a core drill, and it is always quoted against a rod size: the larger the wireline system (BQ < NQ < HQ < PQ), the shallower the same rig can drill. A serious comparison therefore reads the full depth table, then checks whether torque, pull-back force and engine power support that depth in real ground.
The FULONGZUAN YDX series is a fully hydraulic crawler core drill built for diamond and hard-alloy coring, applied across geology, metallurgy, coal, the nuclear industry and hydrology. The YDX-1000 is rated at 1,300 m BQ / 1,000 m NQ / 700 m HQ / 500 m PQ; the larger YDX-1800 at 2,000 m BQ / 1,800 m NQ / 1,300 m HQ / 1,000 m PQ. Main hydraulic components come from internationally renowned brands, and the card-disk rotary head offers lateral translation with a 2-speed gearbox and stepless speed control.

Main Features
Depth in the catalogue is only achievable if the rest of the machine matches it, and the YDX specification is built that way: a load-sensing hydraulic system meters power to demand, the closed-loop dual-motor rotary head sustains 4,600–7,000 N·m of torque at depth, and 150–240 kN of pull-back handles long, heavy rod strings and stuck-pipe recovery. The 11 m mast and 3,800 mm feed stroke keep rod handling efficient, and the working platform can be crawler, skid-mounted or truck-mounted to suit the site.

Frequently Asked Questions
What is the difference between YDX-1000 and YDX-1800?
Capacity and size. The YDX-1800 drills roughly 50–80% deeper across rod sizes (2,000 m BQ vs 1,300 m), with 7,000 N·m torque and 240 kN pull-back against 4,600 N·m and 150 kN, a 194 kW engine against 132 kW, and 13.5 t weight against 9.3 t.
Which rod size should I plan around?
Plan around the core diameter your geology team needs and the target depth: NQ is the common exploration compromise, HQ when larger core or difficult ground is expected, PQ for the largest core at shallower depth. Match the rig whose rating exceeds your deepest planned hole on that rod size.
Can the YDX drill angled holes?
Yes — the mast works across a 45–90° drilling angle range, covering inclined exploration holes as well as vertical ones.
Conclusion
Read as a system — depth table plus torque, pull-back and power — the YDX-1000 and YDX-1800 cover mid-depth to 2,000 m-class diamond core programmes. Share your target depth and rod size with the Simiai Technology trade desk and the matching model can be quoted on an RFQ basis.
