Doosan's new DX140W-3 wheeled excavator is EU Stage IIIB compliant, and is said to offer optimum balance and high mobility for multi-tasking as a tool carrier for attachments such as buckets, breakers, grabs and crushers, as well as providing new levels of comfort, ease of handling.

Designed and built for high productivity in digging, lifting, carrying and other wheeled excavator applications, the DX140W-3 is intended to exceed customer requirements for performance, controllability, fuel efficiency, reliability, durability and reduced overall operating costs, according to the company.

Doosan said the new wheeled excavator was designed to meet the needs of a wide variety of customers, including contracting, civil engineering, rental, utility, road maintenance, recycling, waste handling and building materials companies.

The new ROPS and OPG certified cab offers more space for the operator, while a new cab suspension system helps to cut vibration by 20% and reduce the noise in the cab to as low as 70dB(A).

The machine features a heated air suspension seat designed to reduce operator fatigue as standard. The joysticks have new proportional thumb wheel switches and integrated buttons to provide precise, proportional control of attachments. Forward/Neutral/Reverse (FNR) buttons on the joysticks allow the operator to change direction without removing their hands from the joysticks.

The DX140W-3 is powered by the Doosan DL06K 6-cylinder common rail turbocharged diesel engine providing 101kW of power at 2,000rpm. The DL06K engine meets Stage IIIB emission regulations through the use of EGR (Exhaust Gas Recirculation) and DPF (Diesel Particulate Filter) after-treatment technologies.

A new Eco gauge on the control panel monitors in real time the rate of fuel consumption and actual engine-percent load to help guide the operator to select the best operating mode for fuel economy. Two new modes (P+ mode, Power Plus and L - lifting) aim to improve controllability and efficiency. The new lifting mode is intended to facilitate the handling of heavy objects and materials on construction sites.
