In May 2025, a mining contractor from South Africa purchased two YG big mining excavator machines for gold mine and iron ore excavation projects. After several months of continuous operation under high-temperature and heavy-load mining conditions, the customer achieved excellent performance results in excavation efficiency, fuel consumption control, and equipment stability.
The customer mainly used the machines for:
- Gold ore excavation
- Iron ore loading
- Quarry material handling
- Open-pit mining operations
Compared with their previous equipment, the new YG large mining excavator significantly improved working efficiency while reducing downtime and maintenance frequency.
Customer Challenges Before Using YG Equipment
Before cooperating with YG Machinery, the customer used several locally purchased excavators. However, the machines frequently experienced problems under South African mining conditions.
The main issues included:
- Hydraulic overheating during continuous operation
- Weak digging force in hard rock areas
- High fuel consumption
- Bucket cracking during ore excavation
- Poor climbing performance in uneven mining terrain
- Difficult spare parts replacement for imported systems
Mining operations in South Africa often involve:
- High ambient temperatures
- Dust-heavy environments
- Long working hours
- Heavy rock excavation
- Continuous loading operations
Ordinary excavators struggled to maintain stable performance under these harsh working conditions.
The customer therefore decided to replace the old equipment with a more durable large hydraulic excavator specifically designed for mining projects.
YG Recommended a Heavy Duty Mining Excavator Solution
After analyzing the customer’s mining environment and production requirements, YG Machinery recommended two customized crawler-mounted excavator units specially configured for African mining conditions.
The recommended configuration included:
- Cummins 6-cylinder diesel engine
- Imported Kawasaki hydraulic pump
- KYB main control valve
- Doosan travel motor
- Doosan swing motor with 360° rotation system
- Enlarged radiator cooling system
- Reinforced heavy-duty mining bucket
- 1000mm wide crawler tracks
This customized solution was designed to improve:
- Excavation efficiency
- Hydraulic stability
- Heat dissipation performance
- Terrain adaptability
- Long-hour operating reliability
Why the Customer Chose YG Big Excavator for Sale?
Powerful Engine for Heavy Mining Work
The customer needed a big excavator for sale capable of operating continuously in gold and iron ore mining sites.
YG equipped the machine with a high-performance Cummins 6-cylinder engine featuring:
- Strong torque output
- Stable high-load performance
- Lower fuel consumption
- Better reliability under tropical conditions
Even during continuous heavy digging operations, the machine maintained stable power output.
Imported Hydraulic System Improved Excavation Efficiency
The hydraulic system is one of the most important components of a large hydraulic excavator.
YG excavators use imported Kawasaki hydraulic pumps combined with KYB control valves to provide:
- Faster hydraulic response
- Strong breakout force
- Smooth multi-action operation
- Reduced hydraulic overheating
This was especially important for:
- Hard rock excavation
- Ore loading operations
- Deep mining trench excavation
After replacing the previous machines, excavation cycle efficiency reportedly increased by approximately 25%.
Reinforced Mining Bucket Reduced Damage
The customer’s previous excavator buckets frequently cracked when handling iron ore and hard rock.
To solve this problem, YG provided a reinforced heavy-duty mining bucket with:
- Thickened steel plates
- Reinforced side edges
- Wear-resistant bucket teeth
- Strengthened welding structure
After several months of operation, the bucket showed significantly less wear and reduced maintenance frequency.
Wide Crawler Tracks Improved Stability
South African mining areas often contain loose gravel, uneven terrain, and muddy sections during rainy seasons.
YG equipped the machines with 1000mm wide crawler tracks, which provided:
- Better ground stability
- Lower sinking risk
- Improved climbing capability
- Safer movement in mining areas
The customer reported smoother machine movement and better operational safety compared with the previous equipment.
High-Efficiency Cooling System for African Mining Climate
One of the biggest concerns for African mining customers is overheating.
YG’s enhanced cooling system includes:
- Enlarged radiator structure
- Multi-fin heat dissipation design
- High-efficiency cooling fan system
- Optimized airflow layout
Even under high-temperature mining conditions, the excavators maintained stable hydraulic and engine temperatures during long working hours.
This significantly reduced downtime caused by overheating alarms.
Actual Performance Results After Equipment Upgrade
After using the YG big mining excavator, the customer achieved several operational improvements:
| Excavation Efficiency | Standard | Increased by 25% |
| Hydraulic Stability | Frequent overheating | Stable continuous operation |
| Bucket Damage Rate | High | Significantly reduced |
| Fuel Consumption | Higher | Lower fuel usage |
| Downtime Frequency | Frequent | Greatly reduced |
The customer was especially satisfied with:
- Imported hydraulic system reliability
- Powerful digging force
- Stable cooling performance
- Easy spare parts replacement
Because YG uses internationally recognized components, replacement parts were easier to source locally in South Africa.
