April 2021: Excavators and loaders for your operation

The DX800LC-7 excavator, which is now available after being introduced at ConExpo-Con/Agg 2020, increases Doosan Infracore North America’s footprint in the aggregate industry. The crawler excavator’s size makes it ideal for pit and quarry customers. It can efficiently remove overburden and load large amounts of material into trucks at quarries, Doosan says. Durability and reliability are also prioritized. 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.

Next-gen machine offers production, maintenance solutions

The next-generation Cat 374 excavator offers operators high production, two times more structural durability, and up to 20 percent less maintenance costs than the 374F, according to Caterpillar. Three modes of operation are available: power, smart and eco. Power mode is maximum power at all times. Eco mode lowers engine speed and cycle times while maintaining breakout force. Smart mode takes the guesswork out by automatically matching engine and hydraulic power to digging conditions, reducing fuel consumption and optimizing performance. Engine speed automatically lowers when hydraulic demand decreases, further reducing fuel usage. According to Caterpillar, the cooling system features a new on-demand fan that’s designed to operate only when required, saving fuel and ensuring maximum efficiency.
