Driven by what the company says is the most powerful engine in the 80t class, the DX800LC-7 also has exceptional hydraulic flow for this size of machine, to deliver higher levels of productivity and lower fuel consumption.  Like all Doosan excavators, much attention has been given to operator comfort and safety.  The DX800LC-7 has a new, spacious operator cab, equipped with ergonomic controls and instrumentation, whilst special care has been taken to ensure noise is kept to a minimum through enhanced sealing of the engine compartment and extensive use of sound-dampening materials. All components and assemblies are designed, built and tested to ensure durability. Multi stage filters and features such as track guards and cylinder guards for the boom and arm, the auto grease system and greased and sealed track links are designed to provide reliability and a long service life. The DX800LC-7 is easy to maintain, further reducing downtime to a minimum.    

The DX800LC-7 is primarily intended to serve customers in mining and quarrying 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 and infrastructure projects, particularly where considerable amounts of material need to be excavated and stockpiled or loaded into trucks to be moved. With this extension of its excavator line, Doosan now offers machines from 1t to 80t to serve a wide spectrum of customer needs and applications in construction, mining, rental, landscaping, waste, recycling and forestry.
