Release Date: April 21, 2026
Yantai Sadivo Machinery Co., Ltd. has officially unveiled its heavy-duty flagship model — the SD340 electric excavator. Tailored for high-load operations including large-scale mining, heavy infrastructure construction and mass earthmoving, this machine integrates high-power industrial electric drive, fully reinforced heavy-duty structure, world-class core components and eco-friendly advantages. It delivers a zero-carbon, cost-effective, durable and highly efficient all-in-one solution for heavy-duty construction. Having obtained EU CE certification, it stands out as a high-performance workhorse for premium heavy-duty applications worldwide.
1. Built for Heavy-Duty Operations, Eco-Friendly & Globally Compliant
Positioned as a flagship heavy-duty electric construction equipment, the SD340 is engineered for long-term continuous high-load work, ideal for large mines, heavy infrastructure projects, mass earthmoving, high-level material unloading and other strenuous working conditions.As a pure electric model, it features zero emissions and low noise, fully complying with strict environmental regulations in urban core areas, eco-sensitive zones and emission-restricted mining sites for hassle-free operation. Its power consumption cost is far lower than that of traditional fuel-powered excavators, greatly cutting operational expenses during long-duration heavy-duty work. Combining environmental benefits and economic efficiency, it is the top choice for users pursuing high productivity and reliable performance.
2. Fully Reinforced Structure for Outstanding Durability
The SD340 adopts comprehensive upgrades based on heavy-duty standards to tackle harsh working environments with ease.
Reinforced Boom & Arm Made of thickened high-quality manganese steel, key stress-bearing areas are double-reinforced. Robotic groove welding ensures firm welds and effectively prevents cracking under heavy loads. Professional anti-corrosion and wear-resistant surface treatment enables stable operation in dusty, humid and rainy mining sites. Equipped with large-flow hydraulic cylinders and thickened reinforced pin bushes, it delivers powerful lifting performance and excellent long-term wear resistance.
Heavy-Duty Wiring Harness The whole machine is fitted with heavy-duty wiring harnesses featuring larger wire gauges and higher protection grades, with great resistance to high temperature and aging. Neat layout plus thick protective rubber sleeves at wiring points avoid friction damage and short circuits, ensuring long-term stable and safe operation of the electrical system. The streamlined layout also facilitates quick maintenance and minimizes downtime.
Reinforced Heavy-Duty Chassis The chassis is processed with dual anti-corrosion and wear-resistant treatment, adapting to mining sites, muddy roads and rough terrains. The enlarged ground contact area together with 11 track rollers enhances load capacity and travelling stability, dispersing pressure to avoid deformation and fracture. It effectively prevents skidding and tipping on soft ground, bumpy roads and steep slopes.
Premium Heavy-Duty Undercarriage Track shoes are made of 10mm thick Hangang steel with a 600mm wide design for heavy loads, delivering superior wear resistance, impact resistance and grip. Track links go through professional heat treatment for excellent tensile strength and fatigue resistance. The idler wheel is equipped with an automatic tensioning device requiring no manual adjustment. Carrier rollers adopt heavy-duty sealed bearings for reliable dustproof, waterproof and anti-sand performance. Thickened drive wheel teeth ensure efficient power transmission and lower energy consumption.
High-Grade Hydraulic System Fitted with heavy-duty Kawasaki main pump, perfectly matched with the 110kW high-power electric drive system for steady and smooth hydraulic output. Paired with imported Korean control valves and swing motors, it features quick response, precise control, flexible 360° slewing and reliable braking. Combined movements operate fluently, achieving higher working efficiency than equivalent fuel-powered excavators.
Adjustable Cab Standard DX type height-adjustable cab with a maximum lifting height of 2.5 meters eliminates blind spots, delivering excellent visibility for heavy-duty, high-altitude and long-distance operations. Equipped with mechanical suspension seats to relieve fatigue during long working hours. The LCD display and rear-view camera enable clear monitoring of operating parameters and further improve operational safety and comfort.
3. 110kW Industrial-Grade Electric Drive: High Efficiency, Power & Reliability
Powered by a Siemens 380V three-phase asynchronous motor with a rated power of 110kW and IE3 high energy efficiency rating, this industrial-grade motor guarantees stable performance during prolonged heavy-duty work.
High Energy Efficiency: Low energy consumption and high conversion efficiency. Power cost is only about one-third of fuel-powered excavators, bringing remarkable long-term cost savings.
Durable Design: Fully enclosed self-cooling structure with IP55 protection rating, dustproof, waterproof and splash-proof, suitable for dusty and humid mining environments.
Smooth & Powerful Output: Steady power delivery without stuttering, providing ample power for heavy digging, lifting and unloading.
Easy Maintenance: No need to replace engine oil, oil filters or fuel filters. Daily maintenance is limited to simple electrical inspections, which can be done by ordinary technicians.
The machine offers a continuous working time of 10 to 12 hours. It supports fast charging and can be fully charged in approximately 2 hours, meeting the demands of full-shift daily operations.
4. Custom Export Solutions & Full-Cycle After-Sales Support
The SD340 supports customized configurations to meet different emission standards for export. With EU CE certification, it complies with regulations in the EU, North America, Southeast Asia and other regions. We also provide personalized solutions for track shoe width, cable length and working attachments to fit diverse global heavy-duty working conditions.All units have passed rigorous durability tests and quality inspections. Core components are sourced from world-renowned brands. We provide full-cycle after-sales services and rapid maintenance response, so customers can purchase, use and export the equipment with complete peace of mind.
Conclusion
Boasting five core strengths — heavy-duty specialization, high-power electric drive, fully reinforced structure, low operational cost and global compliance, the Sadivo SD340 electric excavator sets a new industry benchmark for large heavy-duty electric excavators. Aligning with the global trend of green and low-carbon development, it addresses users’ key demands for heavy-duty construction, cost reduction, efficiency improvement, environmental compliance and export certification.
