Doosan Excavators — 2016 Spec Guide
Two Compact Excavators Complement the Company’s Larger Diggers
While Doosan is a relatively young construction equipment brand in North America, the organization has a global manufacturing history going back more than 75 years. Doosan compact excavators complement its line of larger crawler and wheel excavators in a variety of construction applications. They provide customers with compact machines that are designed to access and work in confined spaces, such as residential construction — where larger excavating machines may not fit.
Doosan DX63-3 and DX85R-3 compact excavators are Tier 4-compliant models. They were upgraded from earlier iterations to provide operators with higher-precision controls, greater breakout force and overall enhanced productivity. Improvements from previous Doosan compact excavators include: blade float feature, improved multi-function joysticks, color instrument panel and auto-shift drive system.
Providing best-in-class, over-the-side lifting performance, the DX63-3 is a 58.6-net-hp conventional tail swing compact excavator and weighs 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 8.6 metric tons. The DX85R-3 has 5.8 in. of tail overhang and is designed to work in congested environments and tight spaces next to buildings or other obstructions.
A blade float feature provides Doosan compact excavator operators the ability to smoothly grade, level or backfill material when traveling backward. Operators control the excavator’s dozer blade with an easy-to-access lever.
The excavator’s standard rubber track undercarriage minimizes disruption to existing surfaces and helps the excavator to float across dirt when backfilling material. Auto-shift travel shifts Doosan compact 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 the Doosan DX63-3 and DX85R-3 compact excavators.
Doosan DX63-3 and DX85R-3 excavators have fingertip boom swing and auxiliary hydraulic functions. These functions provide excavator operators with improved multifunction capabilities and more floor space for improved operator comfort. Adjusting variable auxiliary hydraulic flow is easily accomplished via a roller switch on the right-hand joystick.
Similar to instrumentation available for larger Doosan excavators, a multi-language, color, 5.7-in., LCD monitor provides a quick visual of machine vitals. The main screen displays fuel level, coolant temperature, day/time, throttle position and engine rpm. Operators can select auxiliary hydraulic flow modes and rates from the panel.
Doosan compact excavators can complete a variety of jobs with attachments. DX63-3 and DX85R-3 excavators are approved for use with ditching and trenching buckets, and they are hydraulic clamp-ready with durable clamp mounts integrated into the compact excavator’s arm. Two-way auxiliary hydraulic lines with flush-face quick-couplers are standard equipment and allow operators to quickly connect hydraulic attachments.
Advice to Buyers
“If you regularly change attachments to best match digging conditions, consider adding an optional quick-coupler,” says Brian Bereika, Doosan compact excavator product specialist. “Pin-grabber- or wedge-lock-style quick-couplers increase your machine’s versatility and improve your productivity when you are working.”
