Core drilling rigs are deep-hole drilling equipment in the fields of geological prospecting, hydrological water wells, coalfield geological prospecting, oil, and natural gas exploration and development. The core drilling machine has the characteristics of modular design, easy disassembly and assembly, high drilling efficiency, easy transportation, low cost, and environmental protection.

In most cases, it can drill into stratums with depths of more than 350 meters and more than 500 meters and can be widely used in core drilling work with extremely complex ground conditions. It is an ideal equipment for deep-hole geological exploration drilling. Contact us to get a cheap YG core drilling machine price.

3. Walking Type (trailer type) Core Drilling Rig

The core drilling rig is designed with a wheeled walking mechanism and hydraulic cylinder pillars, making it easy to move and adjust the rig’s level. It features a hydraulic feed mechanism that enhances drilling efficiency. Instead of a chuck, the drilling rig is equipped with an upper ball clamping mechanism, enabling continuous bar reversal and ensuring high work efficiency. This mechanism facilitates convenient, safe, and reliable operation.

Additionally, the rig is equipped with a pressure gauge at the bottom of the hole, allowing for easy monitoring of pressure levels and the overall situation inside the hole. The lifting and lowering towers are operated hydraulically, providing convenience and reliability during operation. Moreover, the diesel engine is equipped with an electric start, reducing the labor intensity of workers.

Overall, these features make the core drilling rig user-friendly, efficient, and dependable.

4. Truck-mounted Core Drilling Rig

The drilling rig chassis is equipped with essential components like the driving system, hoisting equipment, and mud pump. The layout is designed to be reasonable and compact, ensuring simple operation.

To ensure the drilling depth and hole diameter, the drilling rig is equipped with a high-pressure mud pump that provides a large flow rate.

The drilling rig is also equipped with a mobile device, allowing for easy front and back movement of the rig itself. This feature is convenient for wellhead operations. Additionally, the hydraulic lifting and lowering automatic telescopic drilling tower of the rig ensures safe and convenient operation.

5. Crawler Core Drilling Machine

The rig adopts an automatic telescopic rig, supported by two high-strength oil cylinders, and a set of hydraulic valves control the rig supine, which saves time and effort, is safe and reliable, and maximizes the benefits for users.

The chassis adopts a rubber track, which is lighter in weight and lower in life cycle cost. It can reduce the noise of the vehicle’s running mechanism, reduce the vibration of the vehicle body, and greatly reduce fuel consumption. It can walk on urban roads without hurting the road surface.

The chassis comes with four high-strength threaded legs (or hydraulic high legs) for quick and convenient installation and adjustment. They can be used for leveling the working plane. Loading and unloading trucks can reduce the cost of lifting and improve efficiency. It can be used as auxiliary support during work.

The 48V electric start diesel engine greatly reduces the labor intensity of the operator, especially when it is difficult to start the diesel engine in the cold season, it shows great advantages.

This machine is equipped with an independent mud pump, which has a large pump flow and pressure and is convenient for maintenance. Parts and accessories can be easily purchased all over the country. Optional installation of hydraulic pipe screwing machines to improve work efficiency and reduce labor costs.
