沃尔沃 EC 210

The Volvo EC210 is a 21-ton crawler excavator equipped with a Volvo D5E turbocharged diesel engine (rated power 123kW/167 horsepower), featuring a new generation of electronic control hydraulic system and high-strength structural components, balancing power output and operational stability. Its bucket capacity ranges from 0.9 to 1.55 cubic meters, with a maximum digging depth of 6.7 meters and a rear rotation radius of 2.86 meters. It combines the efficiency of large equipment with the flexibility of medium-sized machinery. In large-scale projects such as road repair, bridge construction, and underground pipeline laying, the EC210 can quickly complete earth excavation and rock crushing with a bucket digging force of 136kN (power enhancement mode) and a maximum digging depth of 6.7 meters. For medium-sized mines, such as ore loading, breaker operation, and tunnel widening, its reinforced boom and bucket arm, as well as a three-level fuel filtration system, can adapt to high-dust and high-load conditions. User feedback: In the development of Ji Xi terraces, the EC210B has operated continuously for 4,000 hours without major faults, with only oil seals and bucket replacements required. Its durability is remarkable. In forest road construction, pipeline laying, and small-scale mining, its 4.5 km/h traveling speed and 35° climbing ability can flexibly handle rugged terrain. In scenarios such as terraced field development and river dredging, the arm side-shifting function (±45°) and precise hydraulic control enable precise excavation and leveling operations. Efficient and energy-saving: Equipped with the Volvo D5E engine and using SCR selective catalytic reduction technology, nitrogen oxide emissions are reduced by 80% compared to the previous generation, meeting Chinese National IV and European Tier 4 Final/Stage V standards. The intelligent ECO mode and engine automatic idle function can reduce non-operational fuel consumption by more than 7%. Powerful: With a power of 123kW and an optimized hydraulic system, the bucket digging force reaches 136kN, reducing the operation cycle time by 8%, especially in hard rock crushing. Reliability and durability Structural reinforcement: Key components use high-strength steel and stress relief processes, with the boom and bucket arm capable of withstanding over 20,000 hours of heavy-duty operation, with a fault rate lower than that of similar products. Maintenance convenience: Centralized maintenance points, remote filter replacement design, and fault self-diagnosis system can reduce 30% of downtime maintenance time. Intelligence and comfort Precise control: The electronic control hydraulic system response speed is improved by 15%, and the operation handle is designed with low-load feeling, enabling a leveling accuracy of ±5cm. Comfort and safety: The driver's cab, compliant with ROPS/FOPS standards, is equipped with suspended seats, fully automatic air conditioning, and noise reduction technology (noise ≤ 72 decibels), combined with LED night lighting and rearview cameras, ensuring safe operation in all weather conditions. Green technology: The engine uses external cooling exhaust gas recirculation (E-EGR) and particulate filter (DPF), with particulate emissions reduced by 80% compared to the previous generation, compatible with global mainstream environmental protection regulations. Low-noise design: Hydraulic system optimization and intelligent fan control reduce noise by 3-5 decibels compared to competitors, especially suitable for nighttime construction in cities. Fast response: Volvo has service outlets in over 150 countries, providing 24-hour parts support and remote diagnosis services to ensure higher equipment availability. Hedging capability: The brand premium and durability result in a 10%-15% higher residual value rate in the second-hand market compared to Japanese brands, and the long-term holding cost is lower.
