Doosan DX350LC-5


For a crawler excavator that combines solid horsepower, dependable digging performance, and a comfortable cab, choose the Doosan® DX350LC-5 crawler excavator.

A hydraulic system with consistent flow makes it a strong performer on any jobsite, while an electronic power optimizing system (EPOS) provides control, efficiency, and precision.

Work modes further extend your ability to match your machine to your conditions. Choose between digging, lifting, breaker, and shear modes.

A durable x-chassis frame gives you more ground clearance and improves maneuverability while bushings and ultra-hard wear discs are designed for longer service intervals.

Inside the cab, controls are placed exactly where you need them to be. Easily change the control pattern from ISO to BHL to match your preference. Two-way auxiliary hydraulics can now be controlled via joystick switches or the new optional foot pedal control. Select the correct auxiliary flow rate using a switch on the control pattern. A straight travel option is ideal for forward and backward travel in trenching applications.

In any application, an efficient cooling system keeps your machine working hard, even under tough conditions. A variable speed hydraulic fan regulates airflow through the oil cooler. Monitor your Doosan heavy equipment and manage maintenance to reduce operating costs with Doosan Connect Telematics.

Centralized grease points and easy access to other maintenance items including the battery, oil filter, air cleaner, fuel filter, radiators, and other components make maintenance easy.

A spacious cab offers excellent visibility, adjustable controls and high-performance air conditioning. The reclining, height and weight-adjustable standard air suspension seat has a headrest and adjustable armrest. A rear view camera and optional side camera give you more visibility to your work.

To reach Tier 4 emissions standards, the DX350LC-5 incorporates a high-pressure common-rail (HPCR) fuel delivery system as well as cooled exhaust gas recirculation (CEGR) combined with a diesel oxidation catalyst (DOC) and selective catalyst reduction (SCR).
