Doosan DX300LC Medium excavators tech specs

Overview

The Doosan DX300LC (2017–2023) is a 30.9-ton medium excavator aimed at contractors, quarry operators, and earthmoving fleets that need high digging forces and useful bucket capacity for demanding work. Its 147 kilowatt turbocharged Doosan DL08K engine, 1.5 cubic meter bucket, 7.3 m digging depth, and 10.55 m reach make it suitable for bulk excavation, foundations, trenching, loading, quarry support, and major site preparation.

Expert rating: 5 stars

Performance & Efficiency

The 147 kilowatt Doosan DL08K turbocharged engine supports a hydraulic pump flow of 494.32 liters per minute at a relief pressure of 323.62 bar. Its 199 kN bucket digging force and 136.31 kN arm crowding force provide strong breakout performance in compacted ground and bulk excavation, while the 247.13 kN drawbar pull and 35-degree gradeability support movement across difficult sites. The 9.9 rpm swing speed helps maintain steady truck-loading and excavation cycles.

In Comparison

Cat 320: A smaller alternative that is easier to transport and better suited to general construction, but provides less operating weight and bucket capacity than the Doosan DX300LC.
Komatsu PC300: A closer competitor in operating class, suited to heavy excavation, quarry support, and high-volume earthmoving.
Doosan DX300LC: Combines a 30.9-ton platform, 199 kN bucket force, and 494.32-liter-per-minute hydraulic flow for demanding production work.

Final Verdict

Rated 5 stars, the Doosan DX300LC is a strong medium excavator within the AED 300,000–550,000 range. Its powerful hydraulic system, 1.5 cubic meter bucket, long digging reach, and high drawbar pull make it a practical option for bulk excavation, quarry work, foundations, and large site-development projects.
