DOOSAN DX27z & DX30z hydraulic excavators: two new models with novel features

The new DX27z & DX30z (zero tail swing) hydraulic excavators offer additional value to the operator.

These new models were developed with the concept of “providing optimum value to the end user”.

In concrete terms, this translates into :

2

•

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 lead to increased component life expectancy, thus reducing running costs.

•

Reduced maintenance increases the availability and lowers the operating costs of the excavator.

Performance The highest performance is guaranteed in any working condition.

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 and DX30z provide outstanding performance, work efficiency and the ability to adapt to any work environment.

E/G Control Lever The engine speed lever convenient location allows easy engine control.

3TNV82A-SDB (DX27z) – 3TNV82A-PDB (DX30z) engine The DX27z and DX30z have a powerful and eco-friendly heart, that always provides high operating efficiency and pleasant working conditions.

Boom swing The boom swing function permits to work in very narrow areas.

The newly designed swing bracket and the increased boom cylinder size ensures powerful and stable swing performance.

Comfort The cabin has been ergonomically designed with comfort in mind.

Starting a fresh, the newly designed DX27z and DX30z provide the operator with maximum comfort and various convenient features. The DX27z and DX30z are the result of an innovative technical design!

The cabin space is more comfortable than any other excavator in its class.

Comfortable Operating Cabin A ROPS-TOPS roomy, 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 cabin environment.

Cup Holder The conveniently located cup holders add to the operator's comfort.

Defroster The high capacity defroster, installed on the right, eliminating both frost and moisture very efficiently, provides a safer working condition for the operator. (Cabin Type Only) Floor Plate (Rubber mat) The breaker pedal (left) and boom swing pedal (right) are installed in a very spacious and convenient location. In addition, the rubber floor mats contribute to a very comfortable environment. The door opening has been increased by removing the lower lip which provides easy cleaning of the interior.

Joystick The hydraulic joystick levers have very comfortable grips that allow the operator to perform precise operations very easily.

Maintenance The status and condition of all components can be seen at a glance.

The convenient and easy serviceability is really distinguished.

The most advanced technology developed by Doosan Infracore Co., Ltd. was integrated into the DX27z and DX30z excavators for powerful performance and simple, easy maintenance. This provides the operator with convenient maintenance check points and maximizes the work efficiency of the DX27z and DX30z.

Easy maintenance Access to the various coolers is very easy, making cleaning more convenient. The washer fluid level can be checked easily.

D-type Frame The D-type frame and chassis frame add strength and minimize distortion due to shocks.

Air cleaner The large capacity forced air cleaner removes over 99% of airborne particles, reducing the risk of engine contamination, increasing the cleaning and cartridge change intervals.

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 around it.

Air Breather The hydraulic system was designed to prevent the pump from cavitating.

Strengthened Boom The shape of the boom has been optimally designed using finite elements and 3-dimensional computer simulation, allowing the loads to be better distributed throughout the structure. This combined with increased material thickness means improved durability and reliability by limiting element fatigue.

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.

X-chassis The X-chassis frame section has been designed using finite element and 3-dimensional computer simulation, to ensure greater durability and optimum structural integrity. The swing gear is solid and stable.

Bucket Hardened bucket teeth provide durability and can be easily unbolted for removal, straightening or replacing.

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.

Rubber tracks The rubber tracks offer greater non-slip and grip capabilities, 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.
