Three New Mini Excavators Expand the Brand’s Compact Lineup
Doosan has a global manufacturing history going back more than 80 years. Doosan’s mini excavators complement its larger crawler models in a variety of commercial and residential construction applications, as well as landscaping and utility settings. They provide customers with compact machines that are designed to access and work in confined spaces, such as residential construction — where larger excavators may not fit. In 2019, Doosan expanded its lineup of mini excavators with three new models — the DX35-5, DX42-5 and DX50-5 — to offer five machines in this compact equipment category. In addition, Doosan now supplies hydraulic excavators from approximately 3.5 metric tons to its largest model, the DX530LC-5, for a full excavator product offering.
Within the Doosan mini excavator lineup, customers can choose between conventional tail, reduced/minimal tail and zero tail swing models. The new DX35-5 is the smallest Doosan mini excavator available. This 3-ton class excavator is designed with zero tail swing, which makes it an ideal machine for operating on congested jobsites and working next to other objects. The conventional tail swing, Tier 4-compliant DX42-5 has strong bucket breakout force, dig depth and reach in a highly maneuverable excavator in the 4- to 5-ton class. Its relatively narrow width for a machine in its class provides operators greater ability to navigate through doorways, gates and other obstacles. In the 4- to 5-ton size class, the DX50-5 enables customers to operate in tight spaces with superior digging performance. It is a minimal tail swing excavator with less than 1 in. of tail overhang.
Providing best-in-class, over-the-side lifting performance, according to Doosan, the DX63-3 is a conventional tail swing excavator and weighs approximately 6.3 metric tons. It is 77 in. wide and designed to travel between existing homes and along property lines. The larger DX85R-3 also has a 58.6-net-hp electronically controlled diesel engine, is a minimal tail swing compact excavator and weighs approximately 8.6 metric tons. The DX85R-3 has only 5.8 in. of tail overhang and is designed to work in congested areas and tight spaces next to buildings or other obstacles.
The excavator’s standard rubber track undercarriage minimizes disruption to existing surfaces and helps the excavator to easily travel across dirt when backfilling material. An optional angle blade is available for Doosan DX35-5, DX42-5 and DX50-5 models. Auto-shift travel shifts Doosan mini excavators out of high range or low range and back automatically, offering operators travel performance without having to manually downshift. Operators can focus on the direction and speed with this standard feature for Doosan mini excavators.
Doosan mini excavators can complete a variety of jobs with attachments and are approved for use with ditching and trenching buckets. The machines are hydraulic clamp-ready with durable clamp mounts integrated into the mini excavator’s arm. Two-way auxiliary hydraulic lines with flush-face quick-couplers are standard equipment and allow operators to quickly connect hydraulic attachments. If needed, secondary auxiliary hydraulic lines can be added and used to power select attachments.
Advice to Buyers
“Customers should strongly consider upgrading the standard blade to an angle blade,” says Aaron Kleingartner, Doosan Infracore North America LLC marketing manager. “An angle blade makes it easier for mini excavator operators to perform backfill tasks more efficiently, as well as create slopes and swales.”
