DX800LC-7 Crawler Excavator

The 80-ton DX800LC-7 large excavator includes smarter technology and a tougher design for maximum uptime protection. The machine excels in mining, quarry and construction infrastructure.
An innovative double-foot boom design prevents single-side wear patterns by dividing strain between dual boom pins.
Quickly move material with a 5.1-cubic-yard bucket and choose from three excavator arm options — standard, long and mass-excavation. All three include a heavy-duty front design with additional reinforcement on key stress points.
Smarter turning force distribution from the crossed-design swing bearing adds durability and uptime protection.
