Construction equipment supplier Disa Equipment, trading as Doosan, part of the Capital Equipment Group of Invicta Holdings, introduced the low fuel consumption DX220LCA-2 excavator into the 20 t to 22 t class.

“Not only do these robust machines boast pristine manufacturing standards but Doosan’s advanced technologies have also been introduced in the latest excavator series to ensure optimum fuel efficiency, precision control and greater operator comfort. “There is also the added advantage of a more reasonable total cost of ownership and operation,” says Disa Equipment MD Darrel Holton.

Further, the DX220LCA-2 excavator can perform the same challenging operations using less fuel, boasting increased work efficiency. “Fuel consumption has been improved by up to 12%, compared with other machines in this class. This has been achieved by combining quality components and a high-efficiency engine, known for reliability, low fuel consumption and easy maintenance. Doosan’s newly designed main control valve ensures even greater fuel efficiency than the previous model,” he adds.

Doosan’s new engine and pump-matching technology also contributes to reduced fuel consumption and minimal exhaust fumes. Other attributes include the optimised lever control and auto idle facility, which enables the operator to take a break and leave the control joystick fixed, keeping the engine and pump in standby mode, thereby also preventing fuel wastage. Enhancements to the main pump – which include optimised cylinders and higher system pressures – also contribute to improved fuel economy.

The excavator’s engine is capable of 109 kW at 1 800 rpm, with a maximum of 66 Nm at 1 400 rpm.

Meanwhile, the newly designed frames, undercarriage, swing bearing, sprocket roller and reinforced heavy-duty boom and arm offer greater durability. To protect the base of the arm, reinforced bars have been added, and the arm centre and end-boss have been strengthened.

A high class (H class) bucket is installed onto the machine as a base specification with open-type side cutters for improved loading operations. The H class bucket has a maximum capacity of 140 m3.

The newly designed monitor of the DX220LCA-2 excavator clearly displays all the relevant information for different operational scenarios and with the new joystick buttons, the operator can easily select specific features such as braking, fuel efficiency and more demanding tasks.

There is easy access to all components, including the engine oil filter, radiators and grease inlets, subsequently allowing for quick maintenance procedures and the prevention of contamination.

A rotor-type precleaner in the DX220LCA-2 excavators filters out particles larger than 20 mm with more than 99% accuracy.

A larger cooling module ensures an extended service life for every machine and a new vertical fuel-level sensor provides highly accurate information about the fuel level, while the new separate design of the injection and discharge of the grease valve for the idler cylinder reduces the risk of valve failure.

Doosan also offers a technical advisory, maintenance and support service at all its branches and throughout its distributor network.
