You can push this rig through a full 25-meter hole in f=6 to f=20 rock without breaking a sweat, and the 5000 N·m rotation torque paired with that 0-75 r/min speed range means you’re not stuck with one drilling rhythm—you adjust on the fly to whatever the ground throws at you.
It weighs in at 8000 kg, measures 7450 by 2385 by 2805 mm, and the Yuchai 4DKC2G3-100 engine delivers 73 kW at 2200 rpm, while air consumption sits between 15 and 22 m³/min to keep those K40 and K50 hammers happy—personally, I think that engine choice is a solid workhorse for this class.
beam tilts a total of 165 degrees (135 down, 30 up) and swings 90 degrees total, so you can angle into tight spots or steep benches without repositioning the whole machine, and the track leveling adjusts ±10 degrees for when the ground is anything but flat.
For ordering, just tell us your preferred drill rod size—either 76×3m or 89×3m—and we’ll match it to the hole diameter range of Φ105-152 mm, plus we can spec the DTH hammer as K40 or K50 depending on your typical rock conditions.
Travel speed tops out at 3 km/h with a 30-degree gradeability and 350 mm ground clearance, so moving between holes on rough job sites isn’t a chore, and the feed system uses a motor with a reinforced roller chain that holds up well under continuous use.
It carries CE and ISO 9001:2000 certs, which covers most compliance needs out of the box, and the slide plate uses wear-resistant materials to cut down on replacement frequency—just keep an eye on the chain tension during heavy drilling cycles.
Our standard MOQ is 1 unit for the KG690H. We can discuss larger orders depending on availability and production schedule.
Lead time is usually 30-45 days from order confirmation, depending on stock levels and customization requirements.
The KG690H is certified with CE and ISO 9001:2000. We can provide the documentation upon request.
It's designed for f=6-20. Running it on harder rock may reduce drilling efficiency and increase wear on components like the DTH hammer and drill rods.
You'll need an air compressor delivering 15-22 m³/min to match the KG690H's air consumption. Anything less will affect hammer performance, especially with the K50 hammer.
