Doosan Infracore North America expanded its excavator lineup with its largest model yet.

The new Doosan DX800LC-7 increases the company’s footprint in the aggregate industry. The crawler excavator’s size makes it ideal for pit and quarry customers. It’s also well-suited as a large machine for heavy construction and infrastructure work.

The DX800LC-7 can efficiently remove overburden and load large amounts of material into trucks at quarries, Doosan says. On construction sites, the DX800LC-7 excavates, stockpiles or loads large amounts of material. The powerful machine makes these tasks go much faster, the company adds.

According to Doosan, it prioritizes durability and reliability in the DX800LC-7 excavator. The double-boom foot design improves stress distribution to reduce single-side wear and maintain machine uptime. The design allows customers to more easily assemble or disassemble the boom for transportation.

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, Doosan adds. 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.

Additionally, Doosan says the DX800LC-7 provides a high level of efficiency for customers. The excavator’s exclusive 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 system’s efficiency not only improves productivity, Doosan says, but saves on machine fuel consumption. The feature is currently available on the DX350LC-5 excavator and will soon be standard on additional models.
