Get big performance for mid-size applications to move more material every hour with the Doosan® DL320-7. The 7% larger capacity bucket and axle upgrades help you carry and lift larger loads.
Standard features include powershift 4-speed transmission, multiple power modes, Z-bar lift arm, return to dig and limited slip differentials. Reinforced box frame is designed to endure harsh working environments. The improved cooling system features wider radiator fin spacing and a reversible fan to clear debris and reduce clogging. The wider front fender offers better windshield protection.
A high-lift option delivers more lift height and reach — ideal for loading material into high-sided trucks.
For adding flexibility to tackle a variety of applications, an optional larger counterweight can be added to improve machine balance.
A rear full fender option includes a new lock and release handle.
An available automatic lubrication system offers improved machine reliability.
The Load Isolation System (LIS) improves vehicle stability while moving for higher productivity.
A quick coupler allows you to quickly change many non-hydraulic attachments without leaving your seat.
New Doosan Smart Load weighing system is ideal for job applications that require accurate information about material weight in the bucket.
Frequently used controls are relocated for more intuitive use. The Doosan Smart Touch screen displays all important settings and information, including the rearview camera view. Optional electronic steering allows operators to control direction and steer the machine with switches integrated into the left armrest.
All-around visibility is improved with increased glass area, a full glass door, larger mirrors and optional LED work lights. An upgraded heating and air conditioning system with adjustable vent locations maximize heating and cooling efficiency. Helpful tips from the Doosan Smart Guidance System (DSGS) guide operators for more efficient machine operation. The Doosan Smart Key allows push-button engine starts.
Maintenance is quick and easy on the DL320-7 wheel loader with centralized lubrication points plus convenient component access and fluid-level checks.
Easily monitor your DL320-7 and manage maintenance to reduce operating costs with DoosanCONNECT® Telematics. Check machine location, fleet status, operating hours, error codes, fuel usage, engine idle vs. work time, engine and hydraulic oil temperature and various other data points.
Situation Awareness Technology (SAT) 2.0 helps save fuel by automatically adjusting the engine output in real time to the needs of the drivetrain and hydraulics.
Automatic transmission modes shift gears to maximize efficiency. The standard auto-idle feature reduces engine rpm when the steering wheel or joystick isn’t being used, and auto-shutdown turns off the engine after a set amount of idle time.
To comply with Tier 4 emissions standards, the DL320-7 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 diesel exhaust fluid (DEF).
