Coring drill rig is designed for the exploration of solid minerals. The coring drill rig is the mobile crawler-mounted surface coring drill rig. Transportation dimensions conform to standards. The crawler-mounted surface coring drill rig is stable during operation.
MAST of the crawler-mounted surface coring drill rig
Rig design of the mast provides superior performance and reliability even under the toughest geological conditions. Separate allocation of operator work place and mast lift/extend control valve seriously reduces malfunction probability during work.
Hydraulic hoses transporter excludes hoses’ damage probability during operation.
Mast is installed in working position for drilling using two hydraulic cylinders, which are equipped with balancing valves to increase security.
The telescopic mast ensures the reliability of drilling. The underside end of the drilling mast anchors the ground surface while drilling, providing additional stability. While transportation the mast can be moved to center of gravity of the rig for more safety.
OPERATOR PANEL of the crawler-mounted surface coring drill rig
While transportation the operator panel is in closed position in order to avoid breakdowns.
The operator panel is equipped with non-fixing control joysticks, which provide additional safety for the operator. Drilling and rotation joystick with friction damper and non-fixing hoist joystick provide convenience and safe operation. There is auto alarm function for low level of hydraulic oil.
HOOD of the crawler-mounted surface coring drill rig
Fiberglass hood provides excellent sound and heat insulation. Hood tilts with two fixing hydraulic props, which ensure easy access to maintenance of engine and hydraulic system.
HYDRAULIC SYSTEM of the crawler-mounted surface coring drill rig
Hydraulic pumps are directly connected to PTO-driven auxiliary pump, ensuring easy maintenance.
DRILL HEAD
Drill head is suitable for drilling with rods of B-Pseries, rods diameter is from 55,5mmto 114,3mm, inner diameter from main axle is 121mm.
Patented jaws with chuck and hydraulic opening/spring closing function insure fail-safe operation. Spring clap and disk chuck clutch drill rods securely.
Drill head with direct drive from hydraulic cylinder ensure stability during drilling process, as well as more accurate and reliable pressure regulation while drilling with pressure increase or decrease.
OIL COOLING RADIATOR of the crawler-mounted surface coring drill rig
Separately located radiator is equipped with fan adjustment function according to environment temperature.
Radiators placed along increase the hydraulic oil’s cooling efficiency. The drill head is equipped with a separate radiator section.
MAIN WINCH of the crawler-mounted surface coring drill rig
Mounting of main winch on mast minimizes coring drill rig’s vibration.
CRAWLER CHASSIS
Crawler chassis of the drill rig is equipped with hydraulic motors of Korean production, which guarantee high operation quality.
