For Demanding Digging and Lifting
The 48.8-hp DX55R-7 compact excavator offers impressive digging and lifting capabilities ideal for working on congested construction sites.
The reduced tail swing design extends just a few inches beyond the width of the excavator’s tracks, minimizing the chances of hitting objects or buildings when rotating the machine.
The increased counterweight enables offset digging without the need to reposition. The width-protected swing frame allows you to get closer to your work when operating against a structure or obstacle.
Other features include a backfill blade, a rubber track undercarriage and a steel track undercarriage option.
Take on More Jobs With One Machine
A variety of standard features enable immediate multi-attachment functionality and quick attachment changes.
The DX55R-7 features a thumb-ready arm and hydraulic quick-coupler-ready design. No additional accessories are needed to install a compatible quick coupler — which significantly reduces the time it takes to switch attachments including augers, hydraulic breakers and grapples.
Auxiliary hydraulic lines offer quick hose connections to hydraulic attachments. Adjustable flow rates help optimize the response of hydraulic attachments.
When running multi-function attachments, optional secondary hydraulics can be added.
Powerful Telematics and Easy Maintenance
Doosan® -7 Series mini excavators are engineered to keep you on the job — featuring easy access to regular maintenance points and a powerful telematics system included as a standard feature on every machine.
DoosanCONNECT® Telematics monitors the health, location and productivity of your DX55R-7 using a mobile app and website. The system includes an anti-theft feature, which allows you to remotely review, manage and keep track of your machines for added peace of mind.
The swing-open tailgate and side-access hood provide easy access to machine service points, and cooling cores can be separated for easy radiator cleaning.
All-Around Comfort, Control and Visibility
A standard enclosed cab, common Doosan controls and enhanced visibility help take operator comfort to new levels.
The DX55R-7 offers a best-in-class air conditioning system and a deluxe adjustable seat that minimizes heat transfer and vibration from the engine.
The controls, buttons and general operations of the DX55R-7 are similar to those of our large excavators. A thumb switch on the right joystick controls auxiliary hydraulic functions, making fine adjustments effortless. Choose the control pattern you prefer: ISO or BHL.
High-illumination LED lamps, a framed, full glass door and optional rearview camera enhance your work view.
