Doosan DX27Z high-performance
hydraulic excavator
> A model with novel features
Developed with the concept of 'providing optimum value to the end-user', the DX27Z (zero tail swing) hydraulic excavator offers additional value to the operator. In concrete terms, this translates into:
• Increased production and improved fuel economy achieved with the electronic optimization of the hydraulic system and the new-generation engine
• Improved ergonomics, increased comfort and excellent all-round visibility, ensuring a safe and pleasant working environment
• Improved reliability, using high-performance materials - combined with new methods of structural stress analysis - have increased component life expectancy, thus reducing running costs
• Reduced maintenance increases the excavator's availability and lowers the operating costs
Guaranteed highest performance in any work environment
The advanced hydraulic system, combined with a powerful engine, provides the biggest break-out and tractive forces for efficient operation. As a result, the DX27Z provides outstanding performance, work efficiency and the ability to adapt to any work environment
Engine speed lever
The conveniently located engine speed lever allows easy engine control.
Kubota D1105-EF07 engine
The DX27Z has a powerful and eco-friendly heart, always providing high operating efficiency and pleasant working conditions.
Boom swing
The boom swing function allows you to work in very narrow areas
Powerful digging force (bucket)
Powerful, efficient, and with increased digging force. Bucket digging force: 23720 N
Dozer blade
Welded, unitized blade provides durability even under harsh working conditions. Automatically controlled blade floating for quick and easy leveling operations.
Second speed, auto-shift and auto-idle
The travel motors automatically return to high speed after downshifting under load. This allows smoother turns and easier dozing work.
Comfort:
> The cab has been ergonomically designed with comfort in mind
Starting fresh, the DX27Z is the result of an innovative technical design!
The cab space is more comfortable than any other excavator in its class - and the variety of convenient features provide the operator with maximum comfort.
Comfortable operating cab
A roomy ROPS-TOPS, independant minimal shock and low noise operator’s cab with safety glass provides all-round visibility. The right side window opens for ventilation and the front window slides up
Monitor
The centralized display panel provides comprehensive information about the machine in an easy-to-read format. The high-quality display panel is waterproof and all information can be seen at a glance. The ergonomically placed switches maximize convenience for the operator.
Control stand
The left and right control stands are ergonomically placed for convenient operation. The control stand surfaces have ample room to install several option switches. The uni-body plastic design provides the operator with a spacious and comfortable cab environment.
Thumb control for boom swing and auxiliary hydraulics
A thumb control is integrated in the joystick for better metering of the boom swing and the proportional auxiliary hydraulics.
Suspension seat
A fully adjustable suspension seat provides operator comfort during long working days.
Cup holder
The conveniently located cup holder adds to the operator’s comfort.
Lower weight
The lighter machine means that you can tow more attachments on a trailer.
Transportability
Easy to transport with the new integrated upper-structure tie-down points.
Maintenance:
> The status and condition of all components can be seen at a glance. The convenient and easy serviceability is really impressive.
The most advanced technology developed by Doosan Infracore Co., Ltd. was integrated into the DX27Z excavator for powerful performance and simple, easy maintenance. This provides the operator with convenient maintenance check points and maximizes the DX27Z's work efficiency.
Easy maintenance
Access to the various coolers is very easy, making cleaning more convenient. The washer fluid level can be checked easily.
Air breather
The hydraulic system was designed to prevent the pump from cavitating.
Strengthened boom
Using finite elements and 3-dimensional computer simulation, the shape of the boom has been optimally designed for better load distribution throughout the structure. This enhancement, combined with increased material thickness, limit element fatigue for improved durability and reliability.
Arm assembly
In the arm assembly greater strength is gained by using cast elements and
reinforcement around the bosses to increase the life of the component.
Rubber tracks
The rubber tracks offer greater non-slip and grip capabilities, and are less harmful to sidewalks and road surfaces in urban environments. These rubber shoes can be easily installed or removed with the idler, sprocket and other main parts.
Engine room
The engine compartment is designed for easier service, and the sturdy sound-proofing inside the engine cover reduces the noise to provide a more comfortable environment for the operator and those working around the machine.
Oil gauge
Hydraulic oil level can be easily checked through the gauge on the side of
the hydraulic tank.
Grease piping
Integrated grease piping is designed for easy maintenance of the swing bearing and boom swing cylinder
External fuel cap
The external lockable fuel cap makes refueling easy and safe. For extra convenience, a warning beep sounds when the maximum fuel level has been reached.
