CR20 Surface Core Drilling Rig

CR20 has a drilling depth capacity of 2850 meters. Large core samples, a gear driven rotation unit and a constant penetration rate allow the CR20 Surface coring drill rig to boost your productivity and profits. This Surface Drill Rigs fits with Cummins engine and international brand hydraulic components.

CR20 Full hydraulic core drilling rig  has an outstanding external appearance, a compacted structure, reliable functions and a flexible operating system. All these elements have made this hydraulic core drilling rig the best choice among the same products in both domestic and abroad markets.

Equipped with all the essential gauges, including, Rotation speed; Feed Pressure; Ammeter; Voltmeter; Main Pump/Torque gauge; Water pressure gauge. The independent hydraulic oil cooling set can control the oil temperature effectively.The rotation head is a step-less speed transmission, offering a wide range of speeds and torque (up to 3 speeds), the rotation head can be side racked via hydraulic rams for added convenience and efficiency especially during rod trips.The rig provides operator with a nice field of vision and wide and comfortable working condition. The rig looks pretty in overall structure and embodies the design thought of people oriented.

One of the key features of the surface diamond core drilling rig is its ability to obtain high-quality and undisturbed core samples from various types of geological formations. This is important for determining the composition, structure, and properties of the subsurface, as well as for identifying valuable mineral deposits, evaluating foundation conditions, and conducting environmental assessments.

The rig features a hydraulic system for controlling the drilling parameters, such as rotation speed, feed force, and water flow. This allows the operator to adjust the drilling process according to the specific requirements of the formation being drilled, ensuring optimal performance and sample recovery. The rig can be operated by a single operator, thanks to its user-friendly controls and integrated safety features.
