YG Machinery

Why do Cameroonian customers choose the YG Crawler Reverse Circulation Drilling Rig?

The crawler reverse circulation drilling rig, also known as the RC drilling rig, is a high-efficiency drilling device integrating crawler movement, hydraulic drive, and reverse circulation sampling. Its core technology uses a double-walled drill pipe to achieve reverse airflow circulation, rapidly transporting rock cuttings to the surface. It features flexible mobility, high drilling efficiency, and precise sampling. Complementing the fully hydraulic core drilling rig, the former focuses on rapid sampling and efficient exploration, while the latter focuses on obtaining complete rock cores, together meeting Cameroon’s diverse exploration needs.

5 Key Technical Features of YG RC Drilling Rig

1. Tropical High-Temperature Adaptation Design: Designed for Cameroon’s year-round 35°C+ high-temperature environment, it is equipped with a large-capacity cooling system and high-temperature resistant hydraulic oil, allowing for continuous operation for 12 hours without overheating shutdowns, solving the frequent high-temperature failures of traditional drilling rigs.
2. Complex Formation Anti-Stuck Drill Rig Technology: Optimized reverse circulation airflow pressure, adaptable to mixed formations of sand, gravel, and fractured rock in Cameroon, automatically adjusting the slag discharge speed to prevent stuck drill and buried drill accidents, reducing construction risks.
3. Low Energy Consumption and High-Efficiency Drive: Equipped with a Cummins low-fuel-consumption engine, saving 30% more fuel than ordinary reverse circulation drill rigs, adapting to the inconvenient fuel supply situation in remote mining areas of Cameroon, and reducing operating costs.
4. Easy Maintenance Design: Modular layout of core components allows for quick maintenance without specialized tools, and universal wear parts solve the problems of insufficient local technicians and difficulty in procuring spare parts in Cameroon.
5. Off-Road Track Performance: Reinforced steel tracks are suitable for muddy, steep slopes, and gravel roads, eliminating the need for additional towing equipment, allowing direct access to remote exploration areas, and reducing site leveling costs.

Cameroon Client Case Study: Southwest Region Well and Geological Exploration Project

Client Background:

An engineering company in Southwest Cameroon, specializing in rural well construction and municipal geological exploration, serves hilly areas, rainforests, and sandstone-mudstone interbedded strata. Previously, they used small drilling rigs, which suffered from insufficient drilling depth, difficulty in movement, and low efficiency, making them unable to undertake large-scale projects and resulting in weak market competitiveness.

Core Pain Points

• Small drilling rigs have a maximum drilling depth of only 80 meters, insufficient for 150-200 meter deep well construction.
• The rainforest area is muddy and slippery, making it impassable for ordinary drilling rigs, limiting the scope of projects they can undertake.
• Low construction efficiency, with a single well construction cycle of 7-10 days, resulting in fewer than 20 wells completed annually and small profit margins.
• Poor equipment stability; electrical components are prone to damage in the humid rainforest environment, and after-sales response is slow.

Solution

YG’s customized crawler reverse circulation drilling rig (model YG-RC200) is suitable for both water well and geological exploration needs:

• Maximum drilling depth of 200 meters, meeting the requirements of deep well construction and geological exploration. The reverse circulation system allows for rapid slag removal, suitable for sandstone and mudstone interbedded strata.
• Waterproof and moisture-proof electrical system, suitable for high-humidity rainforest environments. Reinforced track anti-slip design, allowing for unimpeded passage on muddy roads.
• Fully hydraulic control system, simple operation, requiring only one person to complete the work, reducing labor costs by 60%.
• Paired with RC drilling rig specific drill bits, wear-resistant and impact-resistant, with a service life 50% longer than ordinary drill bits.

Application Results

1. The construction cycle for a single 150-meter deep water well was shortened to 2 days, increasing annual order volume to 60 wells and revenue by 200%.
2. The equipment is usable in all construction areas, undertaking 3 municipal exploration projects, and expanding market coverage by 60%.
3. Continuous operation without failure in humid environments, reducing the failure rate by 85%, and YG’s overseas after-sales team’s 48-hour response time to resolve after-sales issues.
4. With its efficient construction capabilities, it has become a benchmark enterprise for water well construction in the local area, securing long-term cooperation orders from the Cameroonian water resources department.

Customer Testimonials:

“The YG crawler reverse circulation drilling rig exceeded expectations. It is flexible, efficient, and stable, perfectly adapted to the complex environment of Cameroon, and more suitable for water well construction than the fully hydraulic core drilling rig, helping us double our business!” — General Manager of the Engineering Company
