Used Doosan DX300LC-9C Crawler Excavator | Longmai

The used Doosan DX300LC-9C is a 30-ton crawler excavator designed for demanding construction and earthmoving projects. It combines strong digging force, a large bucket, and a stable long crawler undercarriage. Therefore, it is a practical option for contractors, equipment dealers, rental companies, and project buyers.

The machine has an operating weight of 30,215 kg and a bucket capacity of 1.45–1.6 m³. In addition, its Doosan DL08 engine delivers 159 kW at 1,900 rpm. This performance makes the DX300LC-9C suitable for excavation, loading, roadwork, quarry operations, and large site preparation.

Longmai Machinery supplies used construction equipment for international markets. Buyers can request current machine photos, operating videos, inspection support, loading plans, and export documents before shipment.

Strong Digging and Loading Performance

The Doosan DX300LC-9C provides a bucket digging force of 183.3 kN and a stick digging force of 128.4 kN. As a result, it can handle hard soil, clay, gravel, and other dense materials.

Its 6,245 mm boom and 3,100 mm stick provide a wide working range. The maximum digging radius reaches 10,702 mm, while the maximum digging depth is 7,275 mm. Moreover, the excavator can reach a maximum unloading height of 7,303 mm.

These specifications help operators complete deep excavation and load high-sided trucks with fewer machine movements.

Doosan Engine and Hydraulic Control

Power comes from a six-cylinder Doosan DL08 diesel engine. It produces 159 kW at 1,900 rpm and uses a water-cooled system. Therefore, the engine can support stable operation during long shifts.

The hydraulic system controls the boom, stick, bucket, travel, and swing functions. The machine has a swing speed of 9.4 rpm and a travel speed of 3.2–5.7 km/h. Consequently, operators can position the excavator efficiently and maintain productive work cycles.

A 500 L fuel tank also supports longer operating periods between refueling stops.

Stable Long Crawler Undercarriage

The LC configuration provides a long crawler base for better balance and ground contact. This is useful when working on loose soil, gravel, and uneven sites. Furthermore, the steel tracks provide the durability needed for heavy construction work.

The photographed unit also includes protective guarding around the cab and upper structure. The exact guard design and machine configuration should be confirmed for the available unit before purchase.
