Doosan DX300MH-5
Description
As the largest material handler in the lineup, the Doosan® DX300MH-5 is built for the most demanding material handling functions. It features a fixed 6 ft. cab riser with hydraulic tilt, straight boom and droop nose stick, sandwiched counterweight, rotate grapple ready hydraulics, and additional guarding.
Careful design, high-pressure common rail fuel injection and four valves per cylinder deliver increased torque and efficient fuel consumption. High-capacity pumps improve productivity, while the swing drive provides rapid cycles.
In addition to four power modes, the DX300MH-5 includes lifting work mode, which provides increased pump torque, low engine RPMs, and an automatic power boost.
Cooling features of the DX300MH-5 include a variable speed fan and a split cooling system, which utilizes both hydraulic oil and engine coolant.
To reach Tier 4 emissions standards, the DX300MH-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).

With all of the other performance, comfort and reliability features loaded in all Doosan material handlers, you’ll quickly see why the DX300MH-5 is the picture of productivity.
