The SE390LC is equipped with a Weichai WP10.5H National IV customized engine, with a rated power of 280kW/2000rpm and a displacement of 10.5L. It adopts high-pressure common rail and turbocharging technology, providing ample power reserve山推. Matched with a Linde 210CC fully electronically controlled positive flow hydraulic system, the main pump flow reaches 2×340+20L/min, an increase of about 15% compared to similar models, with low pressure loss, fast response, and smooth combined movements. The customized power curve and electronic control strategy significantly improve fuel economy, with lower fuel consumption in heavy-duty operations山推.
2. Structure and Chassis: Mining-Grade Reinforcement, Durable and Long-Lasting
The machine has an operating weight of 38.7 tons, equipped with a double-tooth heavy-duty track + 9 supporting rollers support structure, with a ground pressure of 70.5kPa, ensuring excellent stability山推. The working device adopts an integral cast boom support + key part reinforcement, with a standard 2.8m stick. High-strength wear-resistant plates cover the vulnerable areas of the bucket and stick, resisting impact from mining gravel. With a bucket digging force of 254kN, arm digging force of 237kN, and maximum traction force of 315kN, it excels in heavy-duty digging, stripping, and loading efficiency山推. The bucket capacity ranges from 0.45 to 2.2m³ (standard 1.95m³), adapting to various heavy-duty scenarios.
3. Intelligence and Comfort: People-Oriented, Efficient, and Safe
It is equipped with a 10.1-inch IPS smart touch screen, visible in strong light, integrating condition monitoring, parameter adjustment, one-key switch between front and rear hand modes, and stepless adjustment of spool response. The new cab adopts six noise reduction technologies + full sealing, with interior noise 2dB lower than similar models; standard air suspension seat + one-key start + rear camera, composite shock absorption, multi-stage air conditioning, ensuring comfort during long hours of operation. Comprehensive safety configurations meet strict mining safety standards. 山推.
4. Maintenance and Economy: Convenient and Worry-Free, Reducing Costs
It adopts an oil-bath air filter + three-stage diesel filter, with a filtration efficiency of 99.9%, adapting to high-dust mining environments. The pull-out oil filter design extends the maintenance interval to 500 hours; the three-stage hydraulic support rod engine cover facilitates inspection; the electronic fuel pump automatically bleeds air, significantly reducing maintenance time and costs.
II. Market Landscape: Rise of Large-Tonnage, Accelerated Breakthrough of Domestic Brands
1. Industry Trends: Growing Demand for Large-Tonnage, Rising Domestic Market Share
In 2026, the excavator market features high concentration, rapid growth of large-tonnage, and accelerated electrification and intelligence. 35–50 ton mining/heavy-duty models have become profit hubs with steady demand growth. Domestic leaders (Sany, XCMG, Shantui, Liugong) continue to squeeze out foreign brands (Caterpillar, Komatsu, Hitachi) in the mid-to-high-end market with cost performance + localized service + rapid iteration, with CR5 exceeding 78%. Overseas markets have become a new engine, with China’s excavator export volume expected to exceed $60 billion in 2026, and large-tonnage models showing obvious advantages in “Belt and Road” mining and infrastructure projects.
2. Competitive Landscape: 39-Ton Segment, China vs. Foreign Brands
- Foreign Benchmarks: Komatsu PC390, Caterpillar 336GC, with mature technology and a high brand premium, but expensive and high maintenance costs.
- Domestic Mainstream: Sany SY395, XCMG XE380, Shantui SE390LC, Liugong 939F, 15–25% lower in price, with similar configurations, fast service response, and easy access to parts.
- Shantui Positioning: Differentiated by mining reinforcement + efficient hydraulics + low maintenance cost, focusing on high cost-performance heavy-duty solutions for core scenarios such as mining, large-scale infrastructure, and quarries山推.
III. Market Value and Competitive Advantages of SE390LC
1. Core Advantages: Precise Positioning, Differentiated Breakthrough
- Golden Combination of Power and Hydraulics: Weichai + Linde, balancing power, efficiency, and fuel consumption, with outstanding heavy-duty performance山推.
- Mining-Grade Structural Durability: Reinforced chassis and working device, longer service life, and higher attendance rate.
- Lower Maintenance Cost: 500-hour long maintenance interval + convenient design, obvious advantages in total cost of ownership (TCO).
- Price and Service: 20%+ lower than foreign brands, supported by Shantui’s national service network and parts supply, with faster response.
2. Target Scenarios and Customer Value
- Core Scenarios: Open-pit coal/metal mine stripping, large-scale infrastructure earthwork, quarries, concrete aggregate processing山推.
- Customer Value: High digging force + high efficiency + low fuel consumption + low maintenance, improving project profitability; stable and reliable, reducing downtime losses; intelligent and comfortable, reducing operation intensity and improving safety.
IV. Prospect Outlook: Backbone Force of Domestic Large-Tonnage Excavators
Driven by mining intelligence, infrastructure upgrading, and overseas expansion, the 39-ton market space continues to expand. With hardcore configuration + high cost performance + full life cycle service, Shantui SE390LC has become an important force in domestic large-tonnage excavators. In the future, with intelligent upgrades (remote monitoring, predictive maintenance), electrification expansion, and deepened overseas localization, the SE390LC is expected to further consolidate its market position and help Shantui achieve greater breakthroughs in the heavy-duty excavator segment.
For customers, the SE390LC is not just a piece of equipment, but an efficient profit partner for heavy-duty scenarios; for the industry, it represents the strength leap of domestic large-tonnage excavators from catching up to running side by side.
