The work rate of a hydraulic excavator is directly linked to the performance of its operator. We have designed the DX420LC by putting the operator at the center of its development goals. The result is significant ergonomic value that improves the efficiency and safety of the operator.


The performance of the DX420LC has a direct effect on its productivity. Its new "Common Rail" engine and new e-EPOS controlled hydraulic system have combined to create an unbeatable hydraulic excavator, with a cost/performance ratio that makes the DX420LC even more appealing.


The reliability of an item of plant contributes to its overall lifetime operating costs. We use computer-assisted design techniques to develop highly durable materials and structures wjhich it tests under extreme conditions. Durability and longevity are our top priorities.
