DIMENSION AND WORKING RANGE
GENERAL SPECS
Even the most brutal workday looks better from the seat of your Doosan wheel loader. Here you command tremendous lift height and capacity, plus enough torque to bite into the toughest materials. Scoop, carry material, load trucks and even run attachments. Cut long days and tough jobs down to size in a hurry and do it profitably in a Doosan wheel loader.
Optimized Engine Horsepower
A finely tuned horsepower curve and higher torque ensure you can move mountains of material fast. A high pressure common rail fuel injection system and cooled exhaust gas recirculation (CEGR) valve reduce emissions.
Outstanding Traction and Pushing Power
Doosan axles are carefully designed to maximize traction, provide easy maneuverability and generate excellent pushing power, making short work of even the biggest pile.
Limited Slip Differential allows the wheel with the most traction to receive the proper torque, providing superior tractive effort and maneuverability in tough terrain.
Lift Capacity
There’s no secret to doing more work in less time. You have to quickly and efficiently handle the biggest, heaviest load that you can. With its load-sensing, closed center hydraulics, Doosan wheel loaders deliver superior lift capacities for every model size.
Self-Adjusting Brakes increase performance and minimize maintenance. If needed, a technician can easily check the brakes and adjust externally. The brake piping is safely integrated with the axle housing and protected from jobsite debris.
Optional Front-Locking Differential locks the front left and right wheels together, providing superior traction for driving over loose, slippery terrain or pushing into big, heavy piles (DL220-5, DL250-5, DL250TC-5 and DL280-5 only).
Power Modes
Choose from three different power modes to change machine performance for job conditions or reduce fuel consumption.
- Power Mode delivers the highest level of performance for quick loading and fast travel. Finish more heavy-duty work in less time.
- Normal Mode is ideal for general work conditions and optimal fuel consumption.
- Economy Mode minimizes fuel consumption and reduces engine sound levels, providing for comfortable, economical light-duty work.
Planetary Final Drives
The planetary final drives transfer torque to the wheels through the transmission and differential. They enable higher travel speeds and greater torque. The outboard, hub-mounted design makes maintenance easy.
Productivity is what it’s all about and Doosan delivers. Whether you’re loading a small truckload or moving a mountain of material, your DL280-5 wheel loader will have you feeling good about the results at day’s end.
Fast Cycle Times
Speed and control are the keys to optimal production. Doosan DL280-5 wheel loader is engineered to perfectly balance both. Durable, low-maintenance vane pumps deliver the power you need to complete every job quickly.
Tier 4 (T4) Compliant
Optimized to provide more power output with reduced fuel consumption, Doosan wheel loaders are designed with T4 compliant engines to reduce air pollution.
Cooled Exhaust Gas Recirculation (CEGR)
CEGR recycles a portion of the engine exhausts to reduce oxygen (O) and lower the temperature in the combustion chamber. This reduces nitrogen oxide (NOx) emissions.
Diesel Oxidation Catalyst (DOC)
In the DOC, carbon monoxide (CO) and particulate matter (PM) emissions are transformed into harmless water (H2O) and carbon dioxide (CO2)
Evaporative Module
In the evaporative module, or mixing pipe, diesel exhaust fluid (DEF) solution is injected in small doses and mixed with hot exhaust gases, decomposing it into urea (CO(NH2)2) and water vapor, which then catalyzes into carbon dioxide and ammonia (NH3).
Selective Catalytic Reduction (SCR)
In the SCR canister, nitrogen oxide mixes with ammonia, and a chemical reaction takes place, resulting in nitrogen (N) and water vapor emitting from the system. The SCR canister also acts as the silencer or muffler.
Diesel Exhaust Fluid (DEF)
DEF is a solution of pure urea and deionized water. A minimum level of DEF is required for proper machine operation, and the DEF supply tank is heated for proper operation in cold weather. DEF is available from your Doosan dealer in various container sizes.
FNR Joystick
Direction changes don’t get any simpler. Just push the joystick buttons to switch between forward, neutral and reverse without even removing your hands from the controls.
Optional Load Isolation System
The load isolation system, sometimes referred to as ride control, cushions the lift arm while traveling over rough terrain, minimizing the loss of material while carrying a load and reducing operator fatigue. It also comes in handy when your customers pay for material by the bucket
Auto Idle
The standard auto idle feature automatically reduces the engine rpm to standby idle a few seconds after the steering wheel, gearshift control lever and accelerator cease movement. This reduces noise, improves jobsite communications and saves fuel. When you move the controls, the loader automatically returns to working idle.
Fuel Efficiency
Fuel use is a significant cost of operation, and Doosan efficiently delivers more work for the money. In our fuel efficiency tests against equivalent machines from other manufacturers, Doosan DL280-5 consistently moves more material per gallon of fuel.
Z-Bar Lift Arm Linkage is designed for heavy lifting in loading applications, with geometry that enables rapid bucket movement and proper angle positioning in every situation.
Standard Lift vs. High Lift
Standard Z-Bar Linkage has excellent breakout forces for easier digging and penetration into tough materials. It increases the lifting capacity of every Doosan loader for best-in-class performance.
Optional High-Lift Z-Bar Linkage is designed for applications requiring the highest possible dumping height and reach. It’s ideal for cement plants, scrap, mulch or wastewater transfer stations.
Parallel Lift Linkage is designed to give you precise control over the movement of buckets, pallet forks and other attachments in applications other than loading. This design keeps the attachment level, allowing for faster lifting and placing of materials.
Return to Dig
Sensors on the lift arm and bucket linkage allow you to change your “return to dig” setting from inside the cab. The cylinders and cutting edge return to the same position every time, enabling more efficient, consistent work.
Lift Kickout
Set the maximum lift height for working inside buildings or other areas with height restrictions. Simply pull back on the control stick to override.
Optional Hydraulic Coupler
This feature increases your productivity with nonhydraulic attachments, such as the pallet fork, saving you time by enabling you to switch from one attachment to the next without even leaving the cab.
Driveline Comparison
The drive shafts and axles* visually remain similar between the two driveline designs; however, the torque converter and four-speed transmission is replaced by a hydrostatic pump and two hydrostatic motors along with a gearbox.
*Front and rear differential configurations may differ between the two systems based on options selected.
Torque Converter Transmission
The automatic powershift torque converter transmission in the DL220-5, DL250-5, DL250TC-5 and DL280-5 is optimized with engine power providing efficiency in load and carry operations. With four gears and three drive modes, the operator has the flexibility to configure the machine to the application. A transfer case is eliminated as the inter-axle differential is integrated in the transmission housing.
Transmission Mode
Choose from three transmission modes manual, auto 1-4 and auto 2-4 with manual kickdown to match the working conditions you face, and tailor performance for better productivity.
Transmission Optimization is a key feature of the automatic transmission modes. It calibrates different shift points to tailor the amount of power and engine torque per gear. When you engage either auto 1-4 or auto 2-4 in power mode or normal mode, the transmission shift point occurs 20 percent later allowing more torque and power within each gear range. In economy mode, the automatic transmission shifts 20 percent earlier for increased fuel efficiency.
Manual is ideal when the job requires precise speed control. Auto 1-4 automatically shifts up when you need more speed and downshifts when the job demands more power or torque. It’s excellent for heavy-duty applications.
Auto 2-4 with Manual Kickdown gives you automatic shifting between gears 2 through 4, with a manual downshift into first gear when you need it. It provides the best performance for less demanding work conditions.
Transmission Cutout
Need more engine power for lift arm speed? In lower gears, simply depress the left brake pedal to disengage the transmission. Disengage transmission cutout with your switch panel to start moving on an incline with greater ease
Hydrostatic Drive System
The new hydrostatic drive system in the Doosan DL200-5 and DL200TC-5 delivers higher performance at lower engine rpm, which also improves fuel efficiency. Additional features include the ability to control the traction characteristics and configure speed management to increase your productivity, and dynamic braking that automatically slows the machine and reduces wear on the brakes.
Single Pump, Dual Motor Hydrostatic System
A single hydrostatic pump directs oil flow to two separate hydrostatic piston motors: one low-speed and one high-speed. These motors are connected to a gearbox that seamlessly transfers power to the driveline from the low-speed or highspeed motor, depending on the demands of the job. If the task demands it, both can power the driveline together. This provides optimal power at all times and automatic torque delivery to the driveline in every kind of application.
Traction Control Management
With traction control management, three modes allow you to easily match traction to the jobsite conditions, so you can prevent wheel slippage while digging, stockpiling and loading.
Max provides maximum traction force.
Traction Control allows you to choose from three intermediate levels of traction force.
Slip is optimized primarily for slippery roadway conditions.
To instantly return to the max traction mode, just press the kickdown button on the joystick control or directional control lever.
Speed Management
A variable speed control feature allows you to obtain full engine rpm for optimal lift arm and hydraulic attachment performance while fine-tuning the maximum machine travel speed in the first gear range. This gives you precise travel control without sacrificing hydraulic power for the job.
