A mining contractor from northern Mexico contacted YG Machinery while preparing for a new mineral exploration program. The company needed a reliable core sample drill rig capable of collecting continuous core samples from complex geological formations. Stable drilling performance, accurate sampling, and easy transportation between multiple drilling sites were the customer’s highest priorities.
The customer planned to drill several exploration holes before expanding the project. After multiple technical discussions and equipment comparisons, YG recommended the YG500 full hydraulic model. The project covered the complete process from the first inquiry and engineering consultation to production, shipment, commissioning, and successful field operation in Mexico.

Understanding the Customer’s Geological Exploration Requirements
The first inquiry arrived through the YG Machinery website. The customer introduced their exploration project, which focused on copper and polymetallic deposits in mountainous areas. Previous drilling equipment frequently experienced unstable rotation, insufficient lifting force, and low drilling efficiency when encountering fractured formations.
During several rounds of communication, both sides discussed drilling depth, hole diameter, transportation conditions, and expected daily productivity.
The customer’s main requirements included:
- Stable core recovery
- Reliable hydraulic system
- Easy transportation between drilling sites
- Low maintenance requirements
- Fast rod handling
- Capability for drilling up to approximately 500 meters
The engineering team also reviewed local working conditions. The drilling locations included gravel layers, weathered rock, and medium-hard bedrock. Daily transportation between exploration sites required good machine mobility and reasonable machine weight.
After evaluating several configurations, YG recommended the YG500 model because its specifications closely matched the customer’s drilling plan while leaving sufficient performance reserves for future projects.

Video Conference About the Full Hydraulic Core Drilling Rig
A video meeting was arranged before finalizing the order. The customer’s drilling supervisor, project engineer, and equipment manager joined the discussion together with YG technical engineers.
The meeting focused on actual drilling operations rather than simply reviewing specifications.
Topics included:
- Core barrel compatibility
- Hydraulic feed control
- Mud circulation system
- Drill rod handling
- Engine maintenance
- Transportation requirements
The customer wanted to reduce operator workload during long drilling shifts. Compared with mechanical rigs previously used by the company, the hydraulic control system offered smoother feed movement and more accurate drilling pressure adjustment.
YG demonstrated several operating videos and explained how hydraulic rotation speed could be adjusted according to different formations. The customer also reviewed maintenance points for the mud pump and hydraulic system before confirming the final configuration.
Why the Customer Selected China Core Drilling Rig
Before placing the order, the customer compared suppliers from China and several other countries.
The final decision was based on technical capability rather than purchase price alone.
Several factors influenced the decision:
- 500-meter drilling capacity
- Fully hydraulic operating system
- Stable lifting performance
- Compact crawler structure
- Professional technical communication
- Complete export experience
The customer explained that geological exploration schedules were tight. Equipment reliability directly affected drilling progress and exploration costs. A machine capable of maintaining continuous drilling with fewer breakdowns would significantly improve project efficiency.
YG also shared previous overseas drilling cases involving geological investigation, mineral exploration, and engineering surveys. This gave the customer additional confidence in selecting a China Core Drilling Rig for the project.

Production, Inspection, and Export Preparation by a Core Drilling Equipment Manufacturer
After receiving the deposit, YG arranged production according to the confirmed schedule.
Manufacturing included frame fabrication, hydraulic assembly, power system installation, and complete machine testing.
Before shipment, technicians inspected several critical systems:
- Hydraulic pressure stability
- Rotation system
- Feed cylinder operation
- Winch lifting performance
- Mud pump operation
- Engine performance
Each operational function was tested before export.
The customer joined the factory inspection remotely through a live video connection. During the inspection, YG demonstrated rod feeding, mast movement, hydraulic controls, and rotation speed adjustment.
After the customer approved the inspection results, the drilling rig received protective packaging suitable for international transportation. Hydraulic ports were sealed, vulnerable components were reinforced, and export documentation was completed before container loading.
Core Sample Drill Rig Commissioning in Mexico
After the equipment arrived at the Mexican port, the customer arranged inland transportation to the exploration camp. Because the crawler chassis allowed the machine to move directly on rough ground, site preparation required very little heavy lifting equipment.
YG engineers provided online commissioning support during installation. The local team completed hydraulic oil filling, mud pump connection, drill rod installation, and system inspection according to the operation manual. The entire commissioning process took less than one working day.
Operator training focused on practical drilling procedures instead of theoretical explanations. The topics included:
- Hydraulic control operation
- Drill rod connection
- Mud circulation management
- Core barrel replacement
- Daily lubrication
- Routine maintenance inspection
After completing several trial holes, the operators became familiar with the machine quickly and officially started the exploration program.

Core Recovery Performance During Field Operation
The first drilling locations contained weathered volcanic rock, fractured formations, and medium-hard bedrock. These conditions had previously caused unstable drilling with the customer’s older equipment.
The new rig demonstrated stable performance from the beginning.
During continuous drilling operations, the hydraulic feed system maintained consistent pressure, allowing the drilling crew to adjust penetration speed according to formation changes. Rotation remained smooth throughout different geological layers, reducing unnecessary vibration.
The project manager reported several improvements during the first month:
- More consistent drilling progress
- Better borehole straightness
- Stable hydraulic performance
- Reduced drill rod handling time
- Lower daily maintenance requirements
Core recovery quality also improved noticeably. Continuous samples provided geologists with more complete geological information, reducing uncertainty during mineral evaluation.
Higher Productivity Across Multiple Exploration Sites
As drilling continued, the customer moved the equipment between several exploration areas within the concession.
The crawler structure simplified relocation between drilling positions. Instead of requiring additional transportation equipment for every movement, the machine could travel independently over uneven terrain within the site.
Several operational improvements became apparent:
- Daily drilling efficiency increased compared with previous equipment.
- Fewer interruptions occurred because of hydraulic instability.
- Operators completed rod handling more efficiently.
- Routine maintenance required less downtime.
- Exploration schedules became easier to maintain.
According to the drilling supervisor, stable equipment performance allowed the geological team to focus more on exploration work rather than machine repairs. This significantly improved overall project organization.
Customer Feedback About Crawler Core Drill Rig After Several Months
Several months after commissioning, the customer shared operational feedback with YG Machinery.
The project manager stated that the machine consistently met the planned drilling depth while maintaining reliable core recovery throughout different formations. Hydraulic controls remained responsive during long drilling shifts, and routine maintenance was straightforward for the local technicians.
The customer particularly appreciated:
- Stable hydraulic operating system
- Smooth drilling control
- Reliable engine performance
- Easy transportation between drilling locations
- Consistent core recovery quality
- Responsive technical support
Following the successful completion of the first exploration program, the customer indicated plans to purchase additional drilling equipment for future mineral exploration projects in other regions of Mexico.
