Industry-leading performance and productivity
The combination of a newly improved engine and a redesigned EPOS-driven hydraulic system with an attractive cost-performance ratio is unrivalled by any other hydraulic excavators in its class.
Durability & stability
Manufactured with surprisingly strong materials and structures, the DX420LCA-K is unrivalled in durability and safety, allowing it to pass rigorous performance tests under extreme conditions. Whenever you work in a tough environment, you can count on Doosan’s DX420LCA-K.
More space, wider visibility, better air conditioning, and a very comfortable seat – all these elements allow the operator to work safely and comfortably for long hours in the best possible conditions.
Short maintenance operations at long intervals increase the machine’s availability onsite at all times. DOOSAN has developed the DX340LCA-K to deliver even higher profitability to the customer.
