Brand New Geological Core Drilling Rig

1.High Drilling Efficiency – Fully hydraulic stepless speed control and automatic feed adjustment increase penetration rate by 30%+, dramatically reducing project time.

2.Easy Operation – Pilot‑proportional or electro‑hydraulic control allows one person to handle all actions (feeding, rotation, rod handling), lowering labor intensity and operator count.

3.Precise Core Recovery – Accurate control of bit pressure, rotation speed, and feed rate ensures high core recovery with minimal disturbance – ideal for fractured or variable formations.

4.Safety & Reliability – Built‑in overload protection prevents sticking or twisting of drill rods. Optional remote control keeps operators away from hazardous zones.

5.Versatile & Portable – One rig suits shallow to deep holes (50m to 1500m+), tough granite, silica‑rich strata, and even grouting/anchoring work. The crawler or modular chassis with hydraulic outriggers enables fast repositioning on mountains, tunnels, or narrow sites.

Product Introduction

The full hydraulic core drill is a core equipment in the fields of geological exploration, mineral resource exploration, engineering geological investigation and other fields. As a professional hydraulic core drilling rig, it achieves efficient, accurate and convenient drilling operations by virtue of its excellent performance of full hydraulic drive, which completely changes the pain point of traditional drilling rigs relying on manual operation and low efficiency. It is suitable for diverse drilling needs from shallow holes to deep holes, and from ordinary rock formations to complex and hard formations. It is widely used in various resource exploration such as metal mines and energy mines, as well as geological disaster control projects, and is one of the preferred core drilling equipment for overseas exploration enterprises.

This full hydraulic core drilling rig adopts an integrated full hydraulic transmission design, and the core executive mechanism is precisely controlled by the hydraulic system. It integrates a number of advanced hydraulic control technologies, with stable operation and reliable performance. It has the advantages of high speed, large torque and large lifting force, which can effectively cope with drilling challenges under complex geological conditions, greatly improve the core recovery rate and drilling efficiency. Some models can achieve more than 97% full-hole core recovery rate in actual exploration, greatly shortening the construction period and meeting the high standards of industrial core drilling.

In terms of operational convenience, the drilling rig has many highlights, among which the automatic hydraulic mast lifting function is particularly practical. There is no need to manually build a derrick. Driven by the precise hydraulic system, the mast can be automatically and stably raised and positioned, which not only saves a lot of manual installation time, but also improves operational safety, adapting to the rapid construction needs in areas with inconvenient transportation such as mountainous areas and forest areas. At the same time, the drilling rig supports multi-angle drilling. Relying on the angle adjustment mechanism, the drilling angle can be flexibly adjusted within the range of 0-90° (some models can be customized with exclusive angle ranges). It can not only realize vertical drilling, but also complete inclined drilling according to exploration needs, easily meeting the operational requirements of different geological investigation scenarios without frequent adjustment of equipment position, greatly improving construction flexibility and adapting to various core exploration scenarios.

As the core component of the drilling rig, the power head is driven by a hydraulic motor, combined with a precision reduction mechanism, which can realize stepless speed change. The torque and speed can be flexibly adjusted to accurately match the drilling needs of different rock formations. Particularly prominent is the automatic left-side rod lifting function of the power head. It breaks the traditional mode of relying on manual assistance for rod lifting. Through the intelligent control of the hydraulic system, the power head can automatically complete the rod lifting action to the left, stably lift the drilling tool and take out the core. It not only reduces the labor intensity, avoids errors and potential safety hazards caused by manual operation, but also shortens the auxiliary time of rod lifting, makes the drilling process smoother and more efficient, effectively reduces the occurrence of downhole accidents, and helps efficient core sample extraction.

In addition, the full hydraulic core drill adopts a modular design, which is easy to disassemble and assemble, and convenient for transfer and transportation. Some models can be equipped with a crawler chassis to realize wireless control walking, adapting to various complex construction sites; at the same time, it is equipped with an independent cooling system, which is energy-saving and environmentally friendly, simple in maintenance, and balances operational efficiency and use cost, making it a cost-effective professional core drilling machine. Whether it is deep mineral resource exploration or engineering geological investigation, this full hydraulic core drill can rely on core advantages such as automatic hydraulic mast lifting, automatic left-side rod lifting of the power head, and multi-angle drilling, as well as stable and reliable overall performance, to provide efficient and accurate equipment support for geological exploration work, help improve the quality and efficiency of exploration work, and meet the core drilling needs of overseas customers.

Adaptation scenario

Our full hydraulic core drill rig is engineered for extreme conditions, operating reliably from -20°C to 50°C and at altitudes up to 4500m without power loss. Its low ground pressure (0.05 MPa) and heavy-duty steel crawler prevent sinking on muddy or soft ground, while four hydraulic outriggers with automatic leveling handle slopes up to 20°, and a compact frame (≤2.2m width) with differential steering (turning radius <2m) enables drilling in tunnels, forests, or confined urban sites. Sealed connectors and an IP65-rated console resist dust and 95% humidity, and the modular design with lifting lugs and fork pockets allows helicopter or truck transport to remote off-grid locations—no external power needed.
