Doosan Construction Equipment is this week launching onto the European market the company’s DX800LC-5B 80tonne crawler excavator.

Ideal for quarrying, mining and major infrastructure projects, the DX800LC-5B is designed to offer optimum value to the end-user and, it is claimed, offers outstanding productivity, high fuel efficiency, superior operator comfort, enhanced reliability, durability and maximum uptime.

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

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

Contributing to 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 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 greater diesel energy efficiency.

Doosan’s ecoPower technology uses an electronic pressure-controlled pump within a closed centre hydraulic system to increase productivity and improve fuel consumption. A closed centred main control valve minimises pressure loss, while the electric pressure-controlled pump manages and optimises engine power more effectively.

The ecoPower system uses sensors to detect the amount of hydraulic oil necessary to accomplish a specific task and precisely meter the amount of oil required rather than continuously forcing a fixed amount of oil through the system, thereby improving efficiency.

The DX800LC-5B has a spacious operator cab, equipped with ergonomic controls and instrumentation. Noise is minimised thanks to improved engine compartment sealing and extensive use of sound-dampening materials.
