Product Description Tunnel Core Drilling RigA tunnel core drilling rig is a specialized mechanical equipment designed for extracting cylindrical rock or soil samples (cores) from tunnel walls or surrounding geological formations during excavation or geological surveys. It features a high-precision rotary drilling mechanism equipped with diamond or carbide-tipped drill bits capable of penetrating hard rock layers. The rig is typically mounted on a stable, adjustable frame to ensure vertical/horizontal alignment and minimize vibration in confined tunnel environments. Integrated hydraulic or electric power systems provide controlled drilling speed and torque, while core retention technology preserves sample integrity for structural analysis. Its compact design allows operation in limited spaces, with dust/water cooling systems to suppress airborne particles. Essential for assessing rock strength, fracture patterns, and groundwater conditions, it ensures safety and informs reinforcement strategies in tunnel engineering projects.Hydraulic underground core drilling rig is suitable fro drilling holes for the purpose of mine exploring,also they could be used in surface coring,railway engineering,tunneling,construction and water conservancy project.Is designed especially for underground 360°drilling work,to drill holes in the tunnel. capable of diamond core drilling and other drilling works.https://sanrock.en.made-in-china.comFeatures: 1.The sliding and extending & retracting function of the mast makes it convenient for the bottom of mast to touches the ground or platform, thus the drill rig will be more stable. 2.The swinging arm and mast can do luffing movement, which satisfy the request of multi-angle drilling. 3.The core drilling machine system of oatation,feed,pumping and clamping relies on fluid drive.4.Under bad transportation condition, the main frame also can be disassembled ,easy to transport. 5.It is light weight, small size, easy operation, with good performance, simple structure and easy to maintain.Product DescriptionSRC400UG HYDRAULIC UNDERGROUND TUNNEL DRILLING RIG Spindle rotational speed280-1200r/minSpindle torque910NmAxial feeding force≥70KNAxial pulling force≥120KNHydraulic system working pressure20MPaMax pressure25MPaMain pump max pressure31.5MPaAuxiliary pump max pressure21MPaPower head stroke1600mmSurface drilling angle0-90Underground drilling angle0-360Azimuth angle0-360Motor Power55KwMotor rotational speed1480rpmMachine body/outer size2800×1020×1550mmWeight1335KgPower car/size1720×690×1420mmWeight765KgConsole/size500×405×1080mmWeight80KgDrilling depth of various diameters BitDrill RodMaterialDrill Depth/mOuter Dia. mmOuter Dia. mmRod MaterialDownHorizontalUPΦ59(BQ)Φ55.6×4.8XJY850550m500m300mΦ75(NQ)Φ69.9×4.8XJY850450m400m250mΦ95(HQ)Φ88.9×5.5XJY850350m300m200m Company Profile1.what can you buy from us?DTH drilling rig,core drilling rig,highway pile driver,solar pile driver ,anchor pile driver,rotary drill rig ,underground jumbo drill rig ,screw air compressor,DTH hammer,drill rod,piston air compressor,pneumatic rock drill ,drill bit,tricone bit ,spare parts.2.How can I make payment?A:You can pay by credit card, TT, Western Union, LC etc.3.
