DX50-5K Doosan excavator specs & dimensions (2021 - 2023)

Excellent Visibility
Doosan's mini excavators provide an expansive glass surface area and upper window to allow optimum visibility of the work.
Better Than a Tractor Loader Backhoe (TLB)
Mini excavators often rework larger TLBs that appear stronger on paper. Where a TLB has a limited swing of 180 degrees, the home of your mini excavator oscillates 360 degrees and rotates continuously for faster and more flexible spoil placement, better visibility and less repositioning in tight-fitting jobs.
Swinging Against Obstacles
A tractor loader backhoe is often restricted to only 45 degree working group movement when faced with an obstacle. With 180 degrees of movement, the excavator offers more freedom for placing spoil or loading trucks. An independent boom swing allows offset digging after square holes or trenching around buried utilities without repositioning. This is virtually impossible in a TLB.
In-Track Swing Frame
The Doosan In-Track Swing Frame design gives you the ability to get closer to your work when offset digging. Bring the excavator flush against a structure or an obstacle. Rocking castings and cylinders are located within the track width; this makes it impossible to damage these components in tight areas while protecting structures and obstacles from damage.
Smooth, Predictable Work Group
Doosan control valves provide smooth, predictable work group control and give you precise movement options that are convenient while working in close environment. Don't sacrifice speed to maintain smoother operation. Doosan excavators deliver both. A unique control valve system and cushioned cylinders offer ample consistent oil flow for the job for fast cycle times and an even, agile response to your commands.
Faster Cycle Times
The difference is clear when digging, dumping spoils into trucks or placing boulders. Doosan mini excavators get the job done faster. With cylinders dimensioned precisely on pump capacities, Doosan excavators always achieve best-in-class cycle times.
Tough Hoses and Smart Routing
Doosan steel hydraulic lines stand up to heavy work better than rubber hoses. They are routed through the lower part of the boom swing casting and safely through the upper part of the boom structure, where they are best protected from wear, tear and damage on the workplace.

Cost Advantages
Mini excavators offer better overall fuel consumption and lower costs while still delivering the power you need for use. Doosan excavators achieve more with smaller variable displacement motors, boosting productivity while using less fuel during a whole day of work.
Auto Idle
To reduce noise, improve job site communication and save fuel, this standard feature automatically drains your engine when machine functions are not used for a few seconds. When you move the controls, the excavator returns automatically to your previous throttle setting.
Tier 4 (T4) Compliance
Doosan's mini excavators are optimized to deliver the ultimate in performance and fuel economy, featuring T4 compliant engines designed to reduce air pollution.
Auto Downshift
When turning, pushing and maneuvering the automatic downshift reduces hydraulic flow so that the machine does not sum up during travel.
Quiet Operator Environment
The quiet engine, together with its solid design and the use of innovative, noise reducing materials, makes the job more pleasant every day. Auto idle feature makes it even easier to be heard or hear your people by automatically emptying the engine after four seconds.

Fingertip Control
A simple thumb switch on the right joystick controls auxiliary hydraulic functions and makes fine adjustments effortless, providing you with improved efficiency and greater comfort throughout your day-to-day work. A thumb switch on the left joystick does not control foot pedals of your boom swing. Not only is this control style more comfortable to operate but it also brings better dosing and improved multifunctioning into the job.
Strong Work Group
The Doosan work group is built tough to ensure a long, productive life of your machine and requires less routine maintenance. It has also been designed with room for adding secondary auxiliary hydraulics. If you need these, you can install a second auxiliary hydraulic option at lower effort and cost.
Auxiliary Hydraulic Lines
Auxiliary hydraulics are configured with flush couplers to allow quick, easy hose connections when using hydraulic attachments. (Models: all) An optional divert valve allows connection of hydraulic thumb hoses when installing other hydraulic attachments.
Fingertip Controls
Auxiliary hydraulic controls are controlled with fingertips to ensure precise positioning and easy operation. Variable flow and detent provide more functionality for the use of different attachments.
Optional Quick Couplers
Quick couplers increase the versatility of your machine and improve your productivity when your work includes gearshifts.

Shorter Tail Swing
For confined spaces, especially in urban environments, a shorter tail swing profile can facilitate maneuvering without sacrificing performance.

Track Advantages
A tracked undercarriage gives you superior flotation and traction on sensitive or soft surfaces that would stop a TLB. Less ground disturbance decreases even during time-consuming, profit reducing repairs to driveways or finished landscaping.

Impressive Lift-Over-Side Capacity
The track system design delivers added stability and an integrated counterweight, allowing operators to dig with confidence.
Built-In Comfort
The sturdy body panels and the narrow latches on the excavator reduce vibration in the cab. A smooth, stable ride as well as a wide seat and ample floor space improve operator comfort and productivity.
Visibility Advantages
In an excavator, the operator sits to the side of the boom for a clear view on the bucket or attachment. Get used to leaning around the boom to see it right at a TLB.
Integrated Slew Brakes
This feature gives you infinite brake positioning for easier loading and positioning of the trailer.
Centralized Boom Swing Cylinder Greasing
Daily maintenance is vital and easy with the centralized grease banks.

Large Cab
Doosan gives you more comfort for long hours of operation. The DX42-5K and DX50-5K have a 15% larger cab than previous models. Flip-up foot pedals provide extra foot space when needed. Adjustable arm rests move exactly where you are most comfortable. Lockable storage keeps your personal belongings safe and out of the way.
