Doosan DX340LC-9C Used Excavator for Construction Site

Build your earthmoving fleet around the work ahead with a used Doosan DX340LC-9C excavator from Longmai Machinery. This crawler model belongs to Doosan’s 9C range, developed for mining, large earthwork projects, and demanding site conditions.

The supplied photos show DX340LC-9C markings, steel tracks, a digging bucket, and an enclosed operator cab. In addition, the machine has front cab screens, an overhead guard, upper-deck handrails, and a rear-mounted camera.

Longmai Machinery supplies used construction equipment for contractors, dealers, rental firms, and project buyers. Customers can discuss machine checks, export documents, parts support, and delivery arrangements before ordering.

Match the Machine to Your Material and Loading Cycle

A heavy excavator should fit the material, digging area, and trucks on your project. The DX340LC-9C can be considered for bulk soil excavation, quarry support, foundation work, and large drainage projects.

First, confirm the bucket size and material density. Then, review the digging depth, reach, and loading height required on site. This helps buyers choose a working setup that suits the daily task.

The pictured machine has a toothed digging bucket. Its capacity, width, wear parts, and suitability for rock or abrasive material should be checked separately.

For repeated truck loading, also consider swing distance and truck position. These factors can affect output even when the machine has enough digging power.

Steel Tracks and a Stable Working Base

The photos show a steel crawler undercarriage with track shoes, chains, rollers, idlers, and sprockets. This arrangement provides ground contact for digging and travel across suitable construction terrain.

However, remaining undercarriage life matters when comparing used machines. Therefore, request measurements of the main wear parts alongside clear photographs.

Check track tension, shoe damage, roller leaks, and sprocket wear. Furthermore, inspect the track frames and lower structure for cracks or previous repairs.

A detailed undercarriage assessment helps buyers estimate maintenance needs before adding the excavator to a fleet.

Cab Equipment Visible on This Unit

The enclosed cab has large glass panels, joystick controls, and a seat with armrests. Meanwhile, the photos show a hydraulic control lock lever and an in-cab display.

Front screens and an overhead guard are fitted to the pictured machine. Their mounting condition and any applicable protective rating should be verified during inspection.

A rear camera is also visible on the counterweight. Buyers should confirm that it provides a clear image on the cab display.

Heating, air conditioning, warning systems, seat adjustment, and control response require an operating check.

Product Configuration and Specification Checks

The quotation should confirm operating weight, engine model, rated power, bucket capacity, hydraulic ratings, digging range, and transport dimensions. These figures must match the selected unit’s serial number and fitted equipment.

The DX340LC-9C should also be identified separately from other DX340LC versions when sourcing parts or comparing specifications.

Check Performance After the Machine Warms Up

An inspection should include a cold start followed by a warm operating test. Next, run the boom, stick, bucket, swing, and travel functions through their working range.

Useful inspection points include:

• Engine starting, exhaust, and fluid leaks

• Cooling performance during operation

• Combined hydraulic movements

• Cylinder drift and seal condition

• Swing response and bearing play

• Travel motors and straight-line travel

• Boom, stick, and bucket joints

• Cab controls and warning indicators

Also, request available maintenance records and details of replaced components. Fresh paint and a clean cab do not establish the machine’s service history.

Plan Ownership Costs Alongside the Purchase Price

The purchase price is one part of the equipment budget. Fuel, wear parts, servicing, freight, and downtime also affect project costs.

Consequently, buyers should review local parts availability and technician support before choosing a unit. A bucket used in abrasive material may need a different wear allowance from one used mainly in soft soil.

Equipment Preparation and Export Delivery

Longmai Machinery supports inspection, export documentation, international shipping, spare-parts supply, and remote maintenance guidance.

Cleaning, servicing, attachment sourcing, and agreed repairs can be discussed for the selected excavator. In addition, preparation work and included equipment should be listed in the order terms.

Transport planning must use measured shipping dimensions and weight. The final method depends on the destination, carrier limits, and whether any components require removal.
