DIMENSION AND WORKING RANGE
GENERAL SPECS
Exceptional power combined with the finest workmanship results in a machine that performs at the highest level. Doosan DL450-5 wheel loader enhance your output from every angle:
- Impressive breakout force and high traction make penetration easy and allow you to tackle the hardest materials.
- Powerful hydraulic system makes work quick and efficient.
- Scania DC13 engine with SCR technology provides the power you need while meeting Stage IV environmental regulations
The combination of these features gives Doosan wheel loaders excellent penetration power, ensuring optimum bucket load in each cycle.
New engine - lower emissions / higher torque
Doosan DL450-5 is equipped with a Doosan engine. Famous for excellent fuel efficiency, reliability and long service life, it combines exceptional power output and high torque at low revs. Common-rail fuel injection is combined with a Variable Geometry turbocharger for faster machine response, even at very low speed. Selective Catalytic Reduction (SCR) technology, combined with a Diesel Oxidation Catalyst (DOC), ensures compliance with Stage IV environmental regulations. As there is no need for a particulate filter, there is no need for regeneration.
Tailored performance
You can select from 3 different working modes: Eco, Normal and Power, while the Power-up function lets you switch the machine into a higher working mode with lower transmission shift intervals by fully applying the acceleration pedal.
Save fuel, save money
To improve your fuel efficiency, an auto shut-down reduces the idle time of the engine, to prevent the over-consumption and useless operating hours. You can easily set the auto shut-down (to stop the engine after 3 to 60 minutes) via the LCD display
ECO gauge
Shows the average fuel efficiency for 1 minute of operation.
Transmission
The Doosan ZF transmission has 5 gears (depending on the country) to boost acceleration performance, especially on climbs with the lockup. The gear ratios are optimised and smooth, and shock-free shifts contribute to the high overall level of operator comfort. Traction force is also maximised. Together, these qualities enable high working speed in all conditions. The transmission has 3 operating modes:
- Manual
- Automatic (working, 1st to 5th gear)
- Automatic (travelling, 2nd to 5th gear)
An automatic kick-down improves the machine's penetration into the pile.
Load sensing hydraulic closed centre system
This system provides maximum hydraulic performance, without producing excess capacity, thus saving fuel and extending the lifetime and reliability of vital components (such as the pumps and the main control valves).
Lock-up: Doosan DL450-5 loader also feature torque converter lockup. When this is activated, the engine automatically connects directly to the transmission (depending on speed and travel resistance), even from 2nd gear. The transmission receives the full engine power without hydraulic slip, thus increasing speed on slope dramatically. This feature can save you up to 10% in fuel costs.
The productivity of your wheel loader is directly linked to the operator’s performance. That’s why Doosan has placed comfort at the very centre of its design priorities for DL450-5 wheel loader.

Plus, our standard machines include a wide range of features at no extra cost (other manufacturers offer these only as options)
Designed to last
We pay the closest attention to the design and manufacture of structural components. Finite Element Analysis is used to ensure an extended lifetime for main structures such as the chassis, joints and lift arm. Then, after modelling, they are subjected to intensive laboratory and field testing in extreme conditions. Ongoing statistical analysis is used to continually increase reliability.
Durable steel parts
Rear parts such as the radiator grille, engine bonnet and fenders are made of solid steel. They’re also designed for easy repair, reducing the need to replace them if they are damaged.
Articulation hinges
The robust hinges feature a clean and solid design and the 40° articulation angle and steering radius are the best in their class.
Exhaust
The inner exhaust pipe sucks air out of the engine compartment through an outer pipe. This ”chimney” effect provides constant air circulation and prevents deposits of flammable material on hot parts.
Auto-lube
Doosan DL450-5 wheel loader are standard equipped with an automatic central greasing system: ‘Auto-lube’ protects components for longer machine lifetime.
ORFS (O-Ring Face Seal)
All hydraulic lines, even the low pressure circuits, are sealed with ORFS couplings to prevent leaks.
Limited slip differentials: Limited slip differentials 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. An optional hydraulic differential-lock can be activated automatically if one tyre starts to slip. The outboard disc brakes enable easy service without dismounting the axles.
Short maintenance operations at long intervals mean you can depend on your equipment being available on-site when it’s needed. Our machines are designed for simple routine maintenance, while skilled Doosan technicians are available to provide extra support when you need it. To get the most out of your machine, you can choose the package you need from a broad range of service agreements. Uptime, productivity and residual value are all maximised, making these wheel loaders an economical and rewarding choice. Building further on the success of the Stage IIIB engines, the Doosan DL08 Stage IV engine does not need a DPF filter to meet the Stage IV emissions requirements. Which means no maintenance required resulting in more uptime!
