Used Doosan DX340LC-9C Excavator for Sale | Longmai

The used Doosan DX340LC-9C excavator is designed for demanding earthmoving, quarry, mining, road construction, foundation, and large infrastructure projects. With an operating weight of about 34.1 tons, strong digging forces, and a large bucket, it offers the productivity required for heavy-duty work.

For contractors, equipment dealers, rental companies, and fleet operators, the DX340LC-9C provides a practical alternative to purchasing a new 30–35 ton excavator. In addition, its widely used Doosan powertrain and hydraulic system make it suitable for long-term commercial operation.

Doosan DX340LC-9C Specifications

The following values are reference specifications for the standard DX340LC-9C configuration. Actual specifications may vary according to production year, boom and arm configuration, bucket size, and machine condition.

34-Ton Heavy-Duty Excavator for Large Projects

At approximately 34.1 tons, the DX340LC-9C sits between standard construction excavators and larger mining-class machines.

This size gives contractors more digging capacity than a typical 20-ton excavator while remaining easier to transport and manage than machines above 40 tons.

Therefore, it is well suited for bulk excavation, quarry loading, large foundations, road construction, pipeline projects, site preparation, and material handling.

The standard bucket range of 1.4–1.6 m³ also allows the machine to move larger volumes per cycle, which can improve productivity on projects with high daily output requirements.

Doosan DL08 Engine with Strong Power Output

The DX340LC-9C uses the Doosan DL08 diesel engine. This six-cylinder turbocharged engine delivers approximately 191 kW at 1,800 rpm.

For heavy excavation, strong low-speed torque is especially important. It allows the excavator to maintain stable hydraulic performance when digging compacted soil, gravel, rock, or heavy construction material.

In addition, the engine and hydraulic system are matched for continuous commercial use. This makes the machine suitable for contractors who need long working shifts and consistent output.

Strong Hydraulic Digging Performance

The hydraulic system is a key advantage of a large crawler excavator.

The DX340LC-9C offers bucket digging force of around 246 kN and arm digging force of approximately 181 kN in the standard reference configuration. Its main hydraulic pumps provide a maximum flow of approximately 2 × 266 L/min.

As a result, the excavator can deliver strong breakout force while maintaining smooth boom, arm, and bucket control.

This performance is useful when loading trucks, cutting into dense soil, excavating foundations, opening quarry faces, or handling heavy materials.

Wide Digging Range for Deep Excavation

Working range is another important factor when selecting a 34-ton excavator.

The standard DX340LC-9C can reach a maximum digging depth of approximately 7.53 meters and a maximum digging reach of around 11.17 meters. Maximum digging height is approximately 10.35 meters.

The extended working envelope reduces unnecessary machine repositioning. Therefore, operators can work more efficiently on deep trenches, drainage channels, foundations, slopes, and large excavation areas.

Stable Crawler Undercarriage

A heavy excavator requires a strong undercarriage to transfer digging force safely to the ground.

The DX340LC-9C uses a steel crawler system with standard 600 mm track shoes. Its wide and long-track structure provides stable ground contact during digging and loading.

For a used machine, our inspection can focus on important undercarriage components such as:

• Track chains and track shoes
• Carrier and bottom rollers
• Idlers and sprockets
• Track tension
• Final drives
• Undercarriage frame

Checking these components before purchase helps buyers better understand future maintenance costs.

Suitable for Multiple Heavy-Duty Applications

The used Doosan DX340LC-9C can serve a wide range of commercial projects, including mining and quarry operations, highway and road construction, large foundation excavation, land development, pipeline construction, demolition preparation, aggregate loading, and large-scale earthmoving.

Different buckets and hydraulic attachments can also be matched according to the application.

Depending on the hydraulic configuration, buyers may request rock buckets, heavy-duty buckets, hydraulic breakers, rippers, grabs, or other compatible attachments.

Used Excavator Inspection Before Export

For international buyers, machine condition is more important than appearance alone.

Before shipment, Longmai can provide current photos, operating videos, and condition information for the available unit. Key inspection points can include the engine, hydraulic pumps, control valves, cylinders, swing system, travel motors, undercarriage, boom, arm, bucket, cab controls, and electrical system.
