DOOSAN DX490LC-3 CRAWLER EXCAVATOR

The Doosan DX490LC-3 is a heavy-duty crawler excavator designed for high performance and durability in demanding construction and earthmoving operations. Powered by a six-cylinder engine producing **389 horsepower (290 kW)** compliant with Tier 4 Interim emission standards, it delivers robust power while optimizing fuel efficiency through an Electronic Power Optimizing System (EPOS) with four selectable work modes and auto-idle functionality. The excavator has an operating weight of approximately **112,502 pounds**, providing a stable and balanced platform for heavy lifting and digging tasks. Its boom and stick configuration allows for a **maximum digging depth of 25.6 feet** and an extended reach along the ground of **38.9 feet**, making it suitable for a wide variety of excavation projects. The machine features increased swing torque (+21%), bucket digging force (+3%), and lifting capacity (+2%) compared to previous models, reflecting enhancements in power and efficiency. The bucket digging force reaches nearly **60,000 pounds**, and the arm digging force is significant, enabling the handling of tough materials with ease. The DX490LC-3 incorporates a variable-geometry turbocharger to boost low-end engine torque and a dual variable-speed hydraulic fan cooling system that improves thermal management by 10 to 15%, ensuring reliable operation under heavy workloads. Maintenance is facilitated by accessible service points, and operator comfort is enhanced by advanced control systems and ergonomic features, resulting in better productivity and reduced fatigue on long jobs. The machine's heavy-duty construction, reinforced boom, and boom wear plates ensure longevity and resistance to harsh operating conditions.
