Doosan Construction Equipment has launched the company’s new 80tonne crawler excavator.


The DX800LC-5B is said to offer optimum value to the end user thanks to outstanding productivity, high fuel efficiency, superior comfort for the operator, enhanced reliability, durability and maximum uptime. These attributes make it ideal for heavy-duty mining and quarrying applications as well as major infrastructure construction projects.

The long carriage (LC) design, in combination with the undercarriage expanded to its maximum working width, offers optimum stability and safety in all kinds of digging, lifting and loading applications.

Built with high-quality, proven main components and offering a very robust design, the DX800LC-5B enables customers to work in environments where avoiding downtime is critical. In fact, the use of superior components throughout, specifically customised for use in large equipment, ensures this new machine offers claimed best-in-class power, productivity and durability.

Contributing to the claimed best-in-class productivity is the combination of a new 358kW diesel engine and a comprehensive advanced and intelligent hydraulic system (ecoPower).

The DX800LC-5B incorporates an Electronic Control Unit which serves to optimise the performance of the diesel engine to achieve the maximum fuel efficiency. The ecoPower technology builds on this by focusing on the role of the hydraulics system and demonstrates Doosan’s continuous iteration of all the processes and components used in the company’s products to achieve unprecedented levels of diesel energy efficiency.

Doosan’s ecoPower technology utilises an electronic pressure-controlled pump within a closed-centre hydraulic system to accomplish increases in productivity and fuel consumption improvements. A close- centre main control valve minimises pressure loss, while the electric pressure-controlled pump manages and optimises engine power more effectively.

The DX800LC-5B has a very spacious operator cab, equipped with ergonomic controls and instrumentation. Special attention has been given to keeping noise to a minimum by improved sealing of the engine compartment and extensive use of sound-dampening materials.
