The Doosan DX345LC is a heavy-duty excavator launched in 2013, representing one of Doosan’s strong entries in the 35-ton class. This machine, manufactured with the collaboration of Doosan’s engineering teams in Korea and production support in Yantai, China, balances durability with performance. Its design focused on delivering high digging power, strong lifting capacity, and efficient fuel economy, making it suitable for large-scale earthmoving, quarrying, and infrastructure projects. With 7900 working hours and currently stationed in Wuhu, Anhui, this unit demonstrates the long service life that these excavators are known for.
Historical Context and Brand Background
Doosan Group, established in 1896, transitioned from a trading company into one of the world’s leading industrial equipment manufacturers. The company entered the construction machinery sector more aggressively after acquiring Daewoo Heavy Industries in the early 2000s. By 2013, the DX series had become internationally recognized, with thousands of units sold across Asia, Europe, and North America. Excavators like the DX345LC contributed significantly to Doosan’s export growth, often chosen by contractors for their reliability in long operating cycles.
Key Specifications

• Operating Weight: 34,700 kg
  
• Bucket Capacity: 1.49 m³
  
• Boom Length: 6500 mm
  
• Arm Length: 3200 mm
  
• Bucket Type: Backhoe
  
• Origin: Yantai (Joint venture/Imported model)
  

Power System
The excavator is powered by the Doosan DE12TIA-C2 diesel engine, a 6-cylinder, 11.05-liter engine equipped with direct injection, turbocharging, and air cooling.

• Rated Power: 188 kW at 1800 rpm
  
• Bore x Stroke: 123 × 155 mm
  
• Cooling: Water-cooled
  This engine is designed to provide consistent torque output, especially in tough digging environments, while maintaining fuel efficiency.
  

Performance Capabilities

• Ground Pressure: 64.7 KPa
  
• Swing Speed: 9 rpm
  
• Bucket Digging Force: 257.9 kN
  
• Arm Digging Force: 180.4 kN
  
• Travel Speed: 5.0/3.2 km/h
  

These figures highlight the DX345LC’s ability to handle deep excavation while keeping cycle times efficient. Operators often praise the balance between swing speed and bucket breakout force, which makes it versatile across different soil types and rock conditions.
Hydraulic System
The excavator uses an advanced variable plunger pump system.

• Main Pump Flow: 2 × 266 l/min
  
• Travel Hydraulic Circuit Pressure: 32.85 Mpa
  
• Swing Hydraulic Circuit Pressure: 26.48 Mpa
  
• Working Hydraulic Circuit Pressure: 32.36 Mpa
  

Cylinder Dimensions:

• Bucket Cylinder: 1 × 150 × 1300 mm
  
• Arm Cylinder: 1 × 170 × 1805 mm
  
• Boom Cylinders: 2 × 150 × 1430 mm
  

This configuration ensures precise control and powerful lifting performance. The plunger pump design reduces hydraulic losses, contributing to better efficiency compared to older gear-pump systems.
Fluid Capacities

• Fuel Tank: 550 L
  
• Hydraulic Tank: 206 L
  
• Engine Oil Replacement: 28 L
  
• Coolant: 20 L
  

The large tank capacity allows for long operating intervals, an important factor for contractors running continuous shifts.
Dimensions

• Overall Transport Length: 11,320 mm
  
• Width: 3280 mm
  
• Height (to hose top): 3445 mm
  
• Cab Height: 3080 mm
  
• Counterweight Clearance: 1195 mm
  
• Ground Clearance: 510 mm
  
• Rear Swing Radius: 3530 mm
  
• Track Shoe Width: 600 mm
  
• Overall Track Width: 3280 mm
  

Working Range

• Maximum Digging Depth: 7450 mm
  
• Maximum Digging Height: 10,150 mm
  
• Maximum Dump Height: 7280 mm
  
• Maximum Vertical Digging Depth: 3970 mm
  
• Maximum Reach at Ground Level: 10,895 mm
  
• Maximum Effective Digging Depth: 7265 mm
  

These working ranges make the DX345LC particularly effective for road construction, deep trenching, and mining operations.
Market Role and Usage Cases
During its release period, the DX345LC became a popular option in Asia-Pacific infrastructure projects, especially in road expansions and dam construction. For instance, in several large-scale railway projects in western China, the DX345LC was among the main machines used for earthmoving, chosen for its ability to sustain long operations with minimal downtime. Its robust hydraulic system made it suitable for rock-breaking attachments, further increasing versatility.
Common Considerations and Maintenance Tips

• Regular monitoring of hydraulic pressure ensures longer pump life.
  
• Fuel filters should be replaced every 500 hours due to dust-heavy work environments.
  
• Track tension must be checked weekly, as improper tension leads to premature wear.
  

Conclusion
The Doosan DX345LC stands as an efficient, reliable, and powerful excavator in the 35-ton category. Its history, combined with proven specifications and strong market acceptance, makes it a machine that continues to deliver value years after its production. Contractors seeking durability and versatility in medium-to-large earthmoving projects often find this model to be a strong choice.
