Doosan DX800LC-7 Crawler Excavator available in North America

December 15, 2020  By Rock to Road

Doosan Infracore North America has expanded its excavator lineup with its largest model yet. The new Doosan DX800LC-7 excavator, which debuted during CONEXPO-CON/AGG 2020, increases the company’s footprint in the aggregate mining industry.

DX800LC-7 customers can choose between three excavator arm options — standard arm, long arm and mass-excavation arm. The arm selection matches the machine to the job so the machine doesn’t waste power. All three excavator arm configurations include a heavy-duty front design with additional reinforcement on key stress points.

The excavator’s crossed design swing bearing supports stress distribution for machine uptime protection. Attention was given to improving wear points — boosting the machine’s reliability and keeping it running longer, according to the manufacturer.

The excavator’s D-ECOPOWER system helps to improve productivity and save fuel. The hydraulic system precisely controls oil flow and optimizes the engine’s available horsepower. The feature is currently available on the DX350LC-5 excavator and will soon be standard on additional models.


Operators can choose between two modes: boom and swing. This allows operators to adjust the machine to best match the job at hand, giving priority to boom or swing movements. Boom priority is ideal in harsh conditions, such as digging over the front or dumping over the side of the machine. Swing priority works best in normal or light-duty digging situations.

The DX800LC-7 can be outfitted with an optional 360-degree all-around view system. The birds-eye perspective gives operators additional views so they can position the excavator in the optimal location for the job. Four cameras and multiple sensors provide input to a second display screen in the cab.

Other features:

  • Two-way auxiliary hydraulic flow
  • Cab guarding
  • Additional work lamps
  • Rotating beacon
  • Straight travel

The DX800LC-7 comes with unlimited access to the DoosanCONNECT telematics system. The system allows equipment owners and fleet managers to remotely monitor machine location, hours, fuel usage, engine idle versus work time and error codes, as well as engine and hydraulic temperatures. Machines can be monitored via an online account.
