product description
what is a drilling rig?
A drilling rig is a heavy machinery that crushes rock and soil layers by rotating the drill bit, and is used for geological exploration or engineering drilling.
This KH612 drill rig machine is a powerful down the hole hammer drill rig, powered by a Yuchai diesel engine, offering stable and reliable performance. Its drilling diameter range is 90 to 120 mm, with a maximum drilling depth of 30 meters, making it suitable for exploration and construction in a variety of geological conditions. Its output torque reaches 1650 Nm, ensuring efficient rock breaking and drilling. Its operating gas consumption is 9-15m³/min, effectively assisting with slag removal and hole cleaning. Furthermore, this crawler drilling rig has good maneuverability and a maximum travel speed of 3 km/h, allows for flexible movement in complex construction environments.
