700-Ton Ultra-Large Mining Excavator – Heavy-Duty Hydraulic Digging Solution for Large-Scale Mining & Quarrying

Overview

The 700-ton ultra-large mining excavator is a flagship heavy-duty hydraulic digging machine engineered for the most demanding large-scale operations, including open-pit mining, large quarrying projects, bulk material handling, and heavy infrastructure construction. As a core piece of equipment for high-production mining sites, it combines a massive structural frame, ultra-large bucket capacity, and high-power hydraulic system to deliver unparalleled digging efficiency, load capacity, and operational stability—outperforming standard excavators in handling overburden removal, ore loading, and rock excavation tasks.

Built to international CE/ISO 9001 standards with heavy-duty components and a modular design, this excavator is optimized for continuous 24/7 operation in harsh working environments (high temperatures, dusty conditions, uneven terrain). As a factory-direct product, it offers customizable configurations, long service life, and low maintenance costs, making it the preferred choice for global mining companies, quarry operators, and large construction contractors seeking to maximize production efficiency and reduce operational downtime.

Core Features & Advantages

1. Unmatched Digging & Loading Performance

700-Ton Operating Weight: Robust structural frame made of high-strength Q690D steel, providing exceptional stability for heavy-duty digging and loading operations—even when handling maximum load capacity.
42m³ Ultra-Large Bucket Capacity: Heavy-duty rock bucket with reinforced wear-resistant steel teeth (high-chromium alloy) and a capacity of 42m³, enabling one-pass loading of bulk materials (ore, overburden, rock) into 200+ ton haul trucks—doubling production efficiency compared to 300-ton class excavators.
High-Power Hydraulic System: 35 MPa high-pressure hydraulic system powered by a 2500 HP diesel engine, delivering a digging force of 2800 kN and a lifting force of 3200 kN. The closed-loop hydraulic circuit ensures smooth, precise control of all boom movements (digging, lifting, swinging) with minimal energy loss.
Efficient Working Cycle: Optimized boom and arm geometry reduces cycle time by 15% compared to competitors, with a fast swing speed (3.5 rpm) and quick bucket dumping—maximizing the number of working cycles per hour for high production output.

2. Reinforced Chassis & All-Terrain Mobility

Heavy-Duty Crawler Chassis: 3.2m-wide reinforced crawler tracks with multi-layer steel plates and rubber pads (wear-resistant), distributing the 700-ton weight evenly to minimize ground pressure (≤0.35 MPa). The chassis is designed to withstand impact from rock falls and uneven terrain in mining sites.
Advanced Suspension System: Hydraulic shock-absorbing suspension between the crawler frame and upper structure, reducing vibration during operation and protecting critical components (hydraulic pumps, engine) from damage—extending service life by 20%.
Excellent Traction & Maneuverability: Dual high-torque track motors with a maximum travel speed of 3.5 km/h, providing exceptional traction on muddy, rocky, or uneven ground. The compact turning radius (≤12 meters) enables easy navigation in large mining sites.

3. Durability Engineered for Harsh Working Conditions

Heat & Dust Resistant Design:
- Engine compartment with a dual-circuit cooling system (air-cooled + water-cooled) and a large-capacity radiator, operational at ambient temperatures up to 55°C—preventing overheating during continuous 24/7 operation.
- Sealed hydraulic and electrical systems with IP67 dust-proof/waterproof rating and high-efficiency air filters, protecting internal components from dust, sand, and water ingress in mining and quarrying environments.
Wear-Resistant Components: All key wear parts (bucket teeth, cutting edges, crawler pads) are made of high-hardness wear-resistant steel (HB400-HB500), with replaceable bolt-on design for easy maintenance and reduced replacement costs.
Corrosion-Resistant Coating: Multi-layer anti-rust system (zinc-rich primer + epoxy midcoat + polyurethane topcoat) on all steel structures, protecting against corrosion in humid or chemically corrosive mining environments (e.g., coal mines, salt mines).

4. Intelligent Operation & Enhanced Safety

Ergonomic Operator Cab: Spacious, soundproof, and vibration-dampened cab with air conditioning, heated seat, and an adjustable suspension system. The 12-inch touchscreen display (multi-language support) provides real-time monitoring of engine performance, hydraulic pressure, fuel consumption, and maintenance alerts.
Intelligent Control System: Equipped with a GPS-based fleet management system and remote monitoring function, allowing operators and managers to track machine location, working status, and fuel usage in real time. Optional autonomous operation mode for repetitive tasks (e.g., overburden removal).
Comprehensive Safety Protections:
- Overload Protection System: Auto-shuts down hydraulic operations when exceeding rated load to prevent structural damage.
- Rollover & Tip-Over Protection: Reinforced ROPS/FOPS-certified cab and anti-rollover hydraulic valves, protecting the operator in case of chassis tilt or impact.
- Emergency Stop System: Hardwired emergency stop buttons in the cab and on the machine body for instant shutdown in critical situations.
- Fire Suppression System: Automatic fire extinguishing system in the engine and hydraulic compartments, essential for mining environments with flammable materials.

5. Customizable Configurations for Project Needs

Bucket Customization: Optional rock buckets, heavy-duty ore buckets, or grab buckets for handling different materials (loose soil, hard rock, coal, gravel). Bucket capacity can be adjusted from 38m³ to 45m³ based on project requirements.
Power System Options:
- Diesel Engine: 2500 HP 16-cylinder high-power diesel engine (Cummins/MTU) compliant with EU Stage IV emission standards, offering low fuel consumption and high reliability.
- Electric Motor: Optional 2000kW high-voltage electric motor for zero-emission operation in underground mines or areas with strict environmental regulations.
Boom & Arm Options: Reinforced long-reach boom (up to 35m) for deep excavation tasks (e.g., open-pit mine benching) or a short heavy-duty boom for high-force rock digging.
Additional Accessories: Optional hydraulic breaker for rock demolition, ripper attachment for breaking hard soil/rock, and a quick coupler for fast bucket/attachment changes.
