JRK-5 Hydraulic Core Rig
1.Main Application and Performance
JRK-5 hydraulic core rig applies to diamond drilling and wire-line coring drilling technologies. It also can be used in geological exploration and drilling technology in many fields.
The hydraulic core rig contains hydraulic pump, hydraulic motor, main valve, windlass, transmission, hydraulic oil cooler, liquid pressure gauge, hydraulic hose and drill tower. Except drill tower which is made of high-class alloy steel, the other parts are all imported from other countries. The self-propelled steel-tracked chassis has good ability in cross-country and climbing slope.
The advanced instrument of rig has the feature of easy operation, position accuracy, stable performance, compact structure and proper distribution. And the machine has attractive appearance.
