Core Advantages of YG Large Mining Excavators

Powerful 6-Cylinder Engine for Heavy-Duty Excavation

The machine adopts a high-power 6-cylinder engine with strong torque output and stable performance.

Advantages include:

• Faster digging speed
• Better climbing capability
• Stable continuous operation
• Lower fuel consumption under heavy loads
• Suitable for high-altitude and high-temperature regions

For mining contractors and earthmoving companies, engine stability directly affects project efficiency and operating costs. A powerful engine helps maintain production capacity even during long working hours.

Imported Kawasaki Hydraulic Pump for Faster Response

The hydraulic system is the “heart” of a crawler hydraulic excavator.

Our excavators use imported Kawasaki hydraulic pumps with:

• Fast hydraulic response

• Flexible operation in confined areas
• Smooth rotation during heavy loading

For quarry and mining applications, stable rotation performance significantly improves loading efficiency.

High-Efficiency Cooling System for Tropical Regions

Overheating is one of the biggest problems for large excavators operating in Africa, the Middle East, and South America.

YG excavators feature:

• Enlarged radiator system
• Multi-fin heat dissipation design
• Larger cooling area
• Optimized airflow channels

This allows the machine to maintain stable hydraulic and engine temperatures even under extreme heat conditions. To ensure global reliability, the excavators can be equipped with world-class engine brands, mainly including Cummins, MAN (Germany), and Isuzu. These engines are well known for:

• Strong power output
• Stable long-hour operation
• Excellent fuel efficiency
• Easy global spare parts availability
• Proven reliability in mining and construction environments

This makes maintenance and parts replacement much easier for overseas customers, especially in remote mining and infrastructure project locations.

It is especially suitable for:

• South Africa mining projects
• Middle East quarry operations
• Southeast Asian tropical construction
• Desert engineering environments

Reinforced Mining Rock Bucket for Harsh Materials
