dPowerful Wheel Loader

P e r f o r m a n c eThe Mega 400-V is a machine that delivers a powerful, highly effective force, offering superior

penetration of the hardest materials. The exceptional drawbar pull at the wheels, is reinforced further

by providing limited-slip differentials as standard equipment. The engine offers high power and torque

characteristics. As a result, the hydraulic system is able to multi-function with power and speed.

ZF AxleImproved internal oil flow greatly reduced the temperature difference between thehub and the differential, as well as prevents premature disc wear due to overheatingof the internal hub components.

LSD (Limited Slip Differential) The standard equipment LSD allows easy drivingthrough soft and swampy grounds.

Increased Axle durabilityThe brake discs have been repositioned to the rear part of the reductiongear where the rotation speed is lower. As a result, the discs areexposed to lower rpm’s and heat generation is reduced and the lifespan of the discs is greatly extended. Automatic disc clearanceregulator has been integrated into the design and the disc clearance ismaintained at the optimum level at all times as the discs wear out. Thisprevents any lag in brake response. Another convenient feature is thatbrake disc wear can easily be measured without disassembling the hub.

The brake piping has been redesigned into the axle housing and isprotected from damage from external shock as the machine drives overrough terrain.

This result may change according to test condition

Turbo Charge Air Cooled Intercooler EngineDE 12TIS, turbo charge air cooled intercooler engineprovides competitive power output and high-efficiency in itsclass. This 6 cylinder turbocharged diesel offers optimalcombustion in all conditions far superior to those stated inthe emissions regulations.

Electro Hydraulic Power steering Works with a flow amplifier and priority valve. And theemergency steering system is equipped as an optionto secure a safety against a malfunction of steeringsystem during traveling.

Full Auto TransmissionThe transmission is particularly smooth and gear ratios perfectlyspaced to give optimal speed. That gives comfort at the sametime that it delivers excellent traction in every working conditions. All of these characteristics, combined, provide a machine thatmakes good shovel penetration.

Axle Oscillation Outstanding Work Safety (oscillation)The center pin support system rear axle can maintain the machine in the horizontal position even in rough terrain achieving themaximum safe operating and driving performance.

Central Monitor PanelThe compact central monitor panel isergonomically designed and allows theoperator to monitor the status andwarning lights at a single glance.

C o m f o r tFrom the beginning, Doosan has had great concern for machine operators.

People need to work in a well-designed and comfortable environment. The work area is spacious, with

several places for storage. The checking and monitoring devices are comprehensive. There is an open

view of the work area. For night work, operators are provided with powerful front and rear lighting.

Switch & Wrist restThe ergonomically laid out switch panelin line with the natural movements of thebody allows for very convenientoperation. The spare switch cut-outsallows easy installation of additionalelectric accessories. The tilting andtelescopic wrist rest allows the operatorto work more comfortably.

M a i n t e n a n c eA liquid crystal display conveys information to the operator relative to the ZF transmission.

At the same time, it reports the nature of a problem (if one exists). When servicing the loader,

a specialised apparatus can be used to adjust the clutch disks to compensate for their wear.

Additionally, by connecting a lap top computer, a complete transmission diagnostic can be performed.

Remote Engine oil &Coolant DrainRemote drain valves havebeen installed in an easilyaccessible location forconvenient draining of fluids.(Coolant - upper, Engine oil- lower)

Remote GreasingLubrication PortsThe front pins can belubricated from the outsideof the machine withoutcrawling under the machineor in awkward positionsthrough the lubrication ports.

A good accessibility at the articulation joint isessential for an easy maintenance.

Oil GaugeAn oil level indicator at thecentre of the machine isclearly visible.

Transmission FilterThe transmission filters arewithin easy reach and likethe rest of the machine’sservice components, can bechecked from ground level.
