DOOSAN at Agritechnica 2017

At Agritechnica 2017, Doosan is unveiling a new wheel loader concept called DL2XX, with a dedicated design for agriculture applications.

The new wheel loader concept will provide the basis for the production of new model in the Doosan range in 2018, to offer agricultural customers an extremely versatile, simple and reliable wheel loader.

The DL2XX is the latest development  in the high performance Doosan wheel loader range, which currently comprises 12 models – covering operating weights from 12 to 35 tonne.

Designed specifically to meet customers’ requirements, the DL2XX offers high performance and high productivity with unbeatable breakout force, tipping load and enhanced output for all agricultural applications.

The DL2XX is powered by the wellproven 5.9 l Doosan DL06 engine which provides high torque, performance and durability in the DL2XX and other models in the Doosan range. Featuring cooled exhaust gas recirculation (EGR), enhanced turbo charger technology and Selective Catalytic Reduction Technology (SCR) without having to use a diesel particulate filter, the DL06 engine is compliant with Stage IV/Tier 4 Final emission regulations.

The engine power is managed via three different working modes: ECO, Normal and Power, to ensure the best torque and power to handle even the toughest work conditions with the best fuel efficiency.

As standard, an auto shut-down reduces the idle time of the engine, to prevent the over-consumption of fuel and wasted operating time. Operators can easily set the timing for this function via the LCD display in the cab.

A maintenance-free air pre-filter automatically removes  debris and separates more than 99% of particles 20 micron and larger, which greatly extends air filter life.

The cooling compartment is equipped with a hydraulic reversing fan to provide very efficient cooling, with a variable speed range from 530 to 1800 rpm. Performance is automatically adapted for lower fuel consumption and shorter warm-up periods. The operator can again easily set standard intervals for the reverse fan from the LCD display in the cab.

The transmission is composed of a torque converter linked to an automatic Powershift transmission to produce a high output to deliver the highest possible traction force. The gear ratios are optimized and smooth, and shock-free shifts contribute to the high overall level of operator comfort.

The DL2XX utilizes 750/50 R26 tyres with drive provided by reinforced axles which ensure a high load capacity. Limited slip differential locks at the front and rear automatically ensure maximum traction and easy driving over soft and muddy ground with no need for a manual differential lock. They also reduce the risk of skidding and prevent excessive tyre wear. A hydraulic differential lock – also available – can be activated automatically if one tyre starts to slip.

The front lift arm is powered by a closed centre hydraulic system with a 210 l/min axial piston pump. This system provides maximum hydraulic performance, without producing excess capacity, thus saving on fuel and extending the lifetime and reliability of vital components.

The DL2XX features Z-bar kinematics with a simple lifting piston system designed for heavy-duty applications. The breakout force of 145 kN  is combined with a constant bucket angle that is maintained throughout the range of movement. Bucket angles are also optimized in the travelling position and at ground level.

The lift arm benefits from an automatic Load Isolation System (L.I.S.) – often called ride control – a standard feature which significantly improves the wheel loader’s ride quality and operator comfort by ensuring a smooth ride over rough terrain and reduced cycle times owing to improved vehicle stability when moving. This provides higher productivity and better fuel efficiency when performing load and carry applications. The speed for automatic activation of the LIS system is fully adjustable by operators.

The operator environment is state-of-the-art, with a modern and attractive work space offering generous headroom and full seat movement provides plenty of  leg room. An ultra-comfortable Grammer seat is a standard feature with vertical and horizontal suspension, heating  and full adjustability.

Materials for the interior of the cab have been carefully selected for their high quality and easy cleaning. In addition, the driver’s belongings are readily at hand, thanks to several storage boxes placed throughout the cab. To ensure a healthy work environment, the cab air is filtered twice to eliminate all particles larger than two microns. The cab also meets ROPS/FOPS regulations – with a wide emergency exit (located on the right hand side) facilitating fast, easy evacuation when needed.

A rear camera provides a clear view of what is happening behind the machine for added safety and peace of mind. The full colour display screen in the cab shows the operator what the camera sees. The panoramic view shows other vehicles coming up behind the loader or people on the ground, and indicators on the screen provide a good perception of distances.

The DL2XX has the DoosanConnect telematics system as standard – offering customers peace-of-mind by being able to remotely locate, safeguard and monitor operating and production parameters for the machine.
