KG420TKG420TH Down The Hole Drill Rig For Open Use

Jining Dongtai Lite Engineering Machinery Co., Ltd. is one of the leading manufacturers and suppliers of kg420tkg420th down the hole drill rig for open use in China. With abundant experience, we warmly welcome you to buy customized kg420tkg420th down the hole drill rig for open use made in China here from our factory. Good service and quality products are available.

When you are out at a quarry, an open-pit mine, or a highway construction site, dealing with slow drilling speeds and stuck drill bits is the last thing you want to deal with. The KG420T and KG420TH open-pit surface drill rigs are built specifically to tackle these exact field headaches.

The complete machine weighs between 4,200 kg and 4,400 kg. It is compact enough to maneuver easily across rough terrain and handles steep climbs without making you nervous.

The KG420T/KG420TH down the hole drill rig for open use is an improved device in compliance with national regulations on diesel-engine emissions. Equipped with the Yuchai four-cylinder engine, the drill rig meets national standards for emissions and environment. The foldirig frame track and four-wheel drive are adopted; Add track leveling cylinders and the plunger piston tramming motor improves the working pressure and increase the rotary torque and revolving speed; and the lifting oil cylinder and chain are expanded to promote the lifting force and reliability. The thickened profile folder is used for the housing, thus improving its level of intensity and rigidity; and the additional ring makes handling and lifting convenient.

The KG420TH down the hole drill rig for open use is equipped with a dust collector, thus making operation more environment-friendly and efficient.

For engineering buyers and procurement teams who need the hard numbers before making a decision, here are the exact operational specifications for both models:

• Plenty of Torque: It uses a heavy-duty plunger rotation motor, meaning the rotary head keeps turning smoothly even when you hit hard rock zones or fractured ground, reducing the risk of getting stuck.
• Practical Hole Size: It handles hole diameters from 90 mm to 130 mm-the sweet spot for standard blasting work-with an economical drilling depth of up to 25 meters.
• Decent Dust Control: It comes with a built-in dry dust collector. It won't clear the air entirely, but it keeps the dust cloud down so the operator isn't choking all day.
• Flexible Positioning: With a climbing capacity of up to 30 degrees and a wide boom swing range, you don't have to waste time shifting the tracks every few minutes just to line up the next hole.
• Reinforced Structural Build: The chassis and feed rail are built from heavy-gauge folded steel plates, giving the rig extra rigidity when tramming over sharp rocks and uneven quarry benches.

(Industry note: While specialized water well drilling rig impactors are relied upon for soft, saturated, or deep hydrological boreholes, these surface rigs are built strictly for medium-to-hard rock fragmentation using high-torque rotation and pneumatic striking power.)
