Hydraulic drilling rig is a kind of high efficient drilling equipment with hydraulic transmission technology, which is widely used in mineral exploration, geological survey and engineering sampling. Compared with traditional mechanical drilling rigs, the YG hydraulic drilling rig stands out for its stronger power output, smoother operation, and higher core recovery rate. Moreover, thanks to its advanced hydraulic control system and durable structure, it performs exceptionally well in deep drilling projects and complex geological formations, making it particularly suitable for exploration operations in South America and Africa.
Hydraulic drilling rig drives the hydraulic motor by high pressure oil pump, rotates the drill pipe and applies axial pressure, and at the same time utilizes the mud circulation system to discharge the rock chips. Its core advantages are:
Precise control of power: the hydraulic system can adjust the rotational speed and pressure in real time to avoid core breakage.
Environmental adaptability: modular design supports quick disassembly, suitable for African mining areas without road transportation conditions.
Why Do Customers Prefer Hydraulic Core Drilling Rigs?
Efficiency and Economy: Taking the Chilean copper mine project as an example, YG hydraulic core drilling equipment for sale reduces the cost of a single hole to $120/m, which is 18% less than pneumatic drilling rigs; 2.
Data Reliability: The stability of the hydraulic system ensures that the core take rate is ≥95%, which meets the JORC standard.
Safety Compliance: ISO 9001:2023 certified, fire and explosion proof design of key components.
Q1: Are hydraulic drilling rigs reliable in high temperature environments? A: The hydraulic oil of YG equipment adopts high-temperature resistant formula (operating temperature -30℃~80℃), and Peruvian customers can run continuously for 1,200 hours without failures in 45℃ desert environment.
Q2: How to solve the rock chip accumulation in deep hole drilling? A: The standard dual-channel mud circulation system, together with Ø66.7mm large ID drill pipe (NTW standard), ensures the cleaning efficiency of deep holes over 200m.
Q3: What is the maximum drilling depth and diameter of YG hydraulic core drilling rigs? A: Depending on the model, YG hydraulic core drilling rigs can achieve a maximum drilling depth of 1,000–1,500 meters, with a drill diameter range from 50mm to 150mm. The system supports multiple core barrel standards such as BQ, NQ, HQ, and PQ, meeting diverse geological exploration needs.
Q4: How efficient is the fuel consumption during long drilling operations? A: The hydraulic power system adopts an intelligent load-sensing pump, which automatically adjusts flow based on real-time resistance. This reduces unnecessary fuel consumption by 15–20%, making it more energy-efficient and cost-effective for continuous operations.
Q5: How often should the hydraulic system and filters be maintained? A: It is recommended to replace the hydraulic filter every 500 hours of operation and check the oil quality every 1,000 hours. Regular maintenance ensures stable hydraulic pressure, extends component life, and minimizes unexpected downtime.
Q6: Can YG hydraulic drilling rigs work efficiently in hard rock or complex geological formations? A: Absolutely. The rigs use high-torque rotary heads (up to 7,000 N·m) and reinforced drill frames, which provide strong penetration capacity even in granite or basalt formations. Optional down-the-hole (DTH) hammer systems are also available for highly consolidated rock layers.
Q7: What support does YG Machinery provide after purchase? A: YG offers online technical guidance, video installation training, and on-site service if needed. We maintain a full range of spare parts inventory, ensuring timely global delivery and quick repair support. Our after-sales team is available 24/7 to assist with troubleshooting.
Q8: Are your rigs suitable for both surface and underground drilling? A: Yes. We provide customizable hydraulic core drilling rigs for surface exploration, tunnel drilling, and underground mineral sampling. The modular design allows flexible configuration for different site conditions and transport limitations.
Q9: What power options are available? A: YG rigs can be configured with diesel, electric, or hybrid power systems. The diesel-hydraulic model is ideal for remote field exploration, while electric models are preferred for low-noise, environmentally sensitive operations such as tunnel projects.
