Doosan offers sneak peek at its largest excavator and hybrid wheel loader

Doosan

ConExpo attendees were able to get a glimpse of Doosan’s largest excavator as well as a concept hybrid wheel loader. 

The new Doosan DX800LC-7 crawler excavator was shown for the first time in North America during the trade show in Las Vegas. 

Paired with a 4.7 cubic metre bucket at ConExpo, the excavator is the biggest model in the company’s excavator line up. 

The DX800LC-7 excavator is designed to serve customers in mining applications, removing overburden and loading large amounts of material into articulated dump trucks or rigid frame trucks. 

The DX800LC-7 may also be operated on large construction sites — particularly at infrastructure jobsites — where a massive amount of material must be excavated and stockpiled or loaded into trucks to be moved. 

A removable counterweight is available as an option and is ideal when the machine requires transportation between sites.

With its extension line of excavators, Doosan offers machines from 3.5 tonnes to 80 tonnes to serve a wide spectrum of customer needs and applications.

The Tier 4-compliant DX800LC-7 is scheduled to be available in North America in late 2020. 

Additional information will be distributed when the machine is available in North America.

Doosan hybrid wheel loader 

A prototype hybrid of the Doosan DL200-5 wheel loader — simply designated as DL Hybrid — was also shown for the first time in North America during ConExpo. While a release date has yet to be announced, hybrid model configurations of the wheel loader could be available in North America as early as 2023.

Doosan is developing the hybrid powertrain to offer the same size wheel loader with additional fuel savings from combining diesel and electric power sources. 

The electric motor and diesel engine work in tandem to provide the same level of torque and output as a larger diesel-only engine. 

The standard DL200-5 wheel loader features an 11,700 kg operating capacity, 413 foot-pounds of torque and  an engine that provides 142 hp at 2,200 rpm, with a 2 cubic meter bucket capacity.

Doosan designed the hybrid machine with a smaller diesel engine than what is used in the standard model today. 

However, there is no noticeable difference in the wheel loader’s performance. 

In addition to offering fuel savings from its hybrid design, the powertrain could be an option for customers working in sensitive areas where environmental concerns are greater than normal. 

Doosan may apply similar hybrid technology to additional wheel loader models in the future.
