Fully hydraulic crawler drilling rig, with their exceptional maneuverability and top-tier drilling efficiency, are widely used in exploration and engineering geological surveying. They are gradually becoming the preferred next-generation solution for deep-hole drilling in complex geological formations worldwide. YG manufactures a range of hydraulic crawler drill machines with varying power ratings and equipped with high-torque rotors, providing customers with solutions for pile foundation work and deep foundation piles up to 1,500 mm in diameter. These machines can be used with various drilling methods, such as DTH, rotary drilling, and auger drilling, to handle a wide range of ground conditions.
Why Choose a Fully Hydraulic Crawler Drill Power System?
Unlike traditional mechanically driven drilling rigs, our fully hydraulic crawler drilling rig uses hydraulic pumps to drive the actuators, achieving a seamless transition from power output to end-point execution.
Technical Advantages of Fully Hydraulic Transmission
·Layout Flexibility: The modular design ensures a compact overall structure, making it better suited for the confined working environments typical of crawler chassis.
·Infinite Speed Control System: Crawler drilling rigs Drill rod rotation speed and feed pressure can be finely adjusted in real-time based on rock hardness, significantly protecting the drilling tools and reducing the risk of rod breakage.
·Pressure Monitoring and Pressure Limiting Protection: Equipped with built-in high-precision sensors, the tracked drill rig system automatically limits pressure when encountering sudden changes in rock formation or the risk of drill bit jamming, ensuring the safety of both the operator and the equipment.
Structural Optimization and Maneuverability
·Remote-Control + Manual Tracked Chassis: Our crawler drilling rig is equipped with an advanced travel system that supports remote operation in complex terrain, enhancing operational safety.
·Telescoping Mast with No Drill Tower: The innovative telescoping mast design eliminates the cumbersome process of erecting a drill tower, enabling “drilling upon arrival.”

Crawler Drilling Rig Applications
·Mineral Exploration: Provides complete, uncontaminated core samples for both preliminary and detailed surveys of metal and non-metal ores.
·Engineering Geology: Suitable for preliminary geological bearing capacity assessments for large-scale infrastructure projects such as high-speed railways, bridges, and dams.
·Hydrogeological Surveys: Capable of handling water extraction and monitoring well operations in special formations such as sand and gravel layers and fractured zones.
·Oil and Gas Exploration: Delivers outstanding performance in shallow oil and gas development and natural gas monitoring.
Crawler Drill Machine Diamond Wireline Coring Drilling Process
To obtain rock cores of the highest quality, we employ the internationally recognized thin-wall diamond wireline coring process.
Diverse Coring Methods
·Wireline Coring: Supports all standard sizes, including BTW, NTW, HTW, BQ, NQ, and HQ. This method eliminates the need for frequent tripping of the drill string, significantly reducing auxiliary operation time.
·SPT Penetration: Designed specifically for soil layers, equipped with a 63.5 kg standard drop hammer and fully automated configuration.
Core Advantages
·Hole Deviation Control: Leveraging the drill string’s full-diameter rigidity, this effectively resolves deviation issues in deep holes.
·High-Quality Core Samples: The recovered core samples retain complete structural integrity and are free from drilling fluid erosion and contamination, providing authentic data for subsequent geological analysis.
Crawler Drill Operating Procedures
High-quality equipment requires scientific operation. Our fully hydraulic crawler drilling rigs follow the standardized procedures below to ensure success at every drilling site:
·Preparation Phase: Level the ground—level the equipment—adjust the mast—dig the mud pit—connect the mud pump.
·Casing Installation: Must reach bedrock to provide essential protection against collapse and debris fallout.
·Drilling Operations: Utilize a dual-tubing drill string with mud pump circulation, connecting drill pipes every 1.5 meters.
·Core Retrieval: Retrieve rock cores using the inner-tubing retrieval method.
Recording and Archiving: Strictly follow core placement protocols for data archiving.
·Site Closure: Raise the drill string and seal the borehole, then restore the site to its original condition in accordance with green exploration standards.
