DL450-5 Doosan DL450-5 Specifications & Technical Data (2015—2021)

Safe operation in all simplicity

Power alone is not enough – for maximum efficiency, it needs to be matched by precise control. Our unique range of features allows every operator to get the most out of these impressive machines. Safety is crucial to your company and your employees – so, these machines feature large platforms, hand-rails, and 2 emergency exits, with maintenance performed from the ground.

Safe access

To facilitate access and mobility on the machine, multiple hand-rails ensure that the operator always has a firm support to hold on to.

Excellent service accessibility

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 new Stage IV Scania engine has no need for a DPF filter to meet the Stage IV emissions requirements. Which means no maintenance required – resulting in more uptime!

Lock-up

The DL450-5 & DL550-5 also feature torque converter lock-up. 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.

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.

Automatic hydraulic differential locks

Hydraulic differential locks on the front and rear automatically engage to ensure maximum tractive effort with a lock of 100% and an easy driving experience. Muddy and slippery areas can be anticipated by the operator with the manual foot control. They also reduce the risk of skidding and prevent excessive tyre wear. The brake discs in the planetary reduction gears are reinforced, ensuring long hours of operation and easy maintenance access. An Automatic Limited Slip Differential lock is also available on the DL450-5 model.

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.

Maintenance access made simple

The front and rear of the radiator – which is made of aluminium for the highest pressure resistance and a long lifetime – are easily accessible.Air enters through the side and top, while swing doors provide easy access for maintenance.A battery cut-off switch makes it easy to disconnect the battery during long-term storage.The hour meter display can be easily checked without turning the engine on.

Reversing 90° swing fan

The fan is located behind the radiator, and air is sucked in from the sides, not from behind the machine. This design allows for easier cleaning access to the one-block radiator from both the rear and the front. The operator can easily set standard intervals for fan reverse from the LCD display, and performance is regulated for lower fuel consumption and shorter warm-up periods.

Simplicity of operations

"Lift arm raise kick-out" and "return to dig" bucket – Automated functions operated electronically from inside the cab.

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.

Productivity

Thanks to their robust design and the use of high-quality components, the Doosan wheel loaders deliver very high performance – ensuring you the best productivity and reliability.

Comfort

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 the DL450-5 & DL550-5. More space, better visibility, a high comfortable seat, and plenty of storage space make it easy to work for hours without fatigue or discomfort. There’s no need to pay extra for the options you want – most of them are standard features on this loader!

Operator environment

A modern and attractive work space offers generous headroom, and seat movement provides lots of leg room. Interior materials are selected for their high quality and easy cleaning. In addition, your belongings are right at hand, thanks to several storage boxes throughout the cab.

Accurate & smooth joystick steering

Keep your concentration and reduce strain with the comfortable joystick steering integrated on the armrest. Drive your machine easily, especially in repetitive tasks and tight spaces.

Automatic air conditioning

Day and night, whatever the weather, set your preferred temperature for the best working conditions. The fully automatic climate control system adjusts air temperature and fan speed to maintain your ideal climate setting.

High-comfort air suspension seat

With vertical and horizontal suspension, the ultra-comfortable, heated and fully adjustable Grammer seat is featured as standard, giving you the feeling of being comfortably installed in your own sofa.

Adjustable steering column

Enhance your driving comfort and work without fatigue by easily adjusting the steering column’s tilt and telescopic movements to fit your preferred position.

Load Isolation System

This standard feature provides a smooth ride over rough ground, operator comfort, and reduced cycle times due to improved vehicle stability in movement. It ensures higher productivity and better fuel efficiency while performing load & carry applications. The speed for automatic activation is adjustable by the operator.

Cab

To ensure a healthy work environment, the cab air is filtered twice to eliminate all particles larger than 2 microns. Plus, the cab satisfies ROPS/ FOPS regulations – a wide emergency exit (located on the right side) provides fast, easy evacuation in a critical situation.

Safe maintenance

All the daily gauges checking takes place from the ground, allowing for quick and safe operation by everyone. Doosan has also installed an automatic greasing system (as standard) to reduce working time and increase operating comfort.

Ergonomic controls

All controls are placed within the operator’s easy reach. Clearly positioned for comfortable access and grouped by function, they enable safe, confident operation. The bucket is controlled by using a convenient joystick or with fingertip levers, both of which include an FNR reversing switch and kick-down function.

Z-bar

"Z" kinematic delivers a huge break-out force, especially for heavy materials, and a large dump angle for unloading sticky materials efficiently.

A Doosan attachment for optimum performance in each activity

Robust construction, excellent penetration, covering several types of applications from light- up to severe-duty. These new Doosan loader attachments are designed and manufactured in Europe to meet local requirements and standards. A large range of attachments guarantees versatility and efficiency all the way. Each bucket is designed for a specific machine model to fit its key kinematic parameters perfectly. Critical bucket positions are optimised to improve digging and dumping. The Doosan attachment concept stands for high quality, perfect fit and excellent operational capabilities.

V-shape Rock buckets

Used for handling and digging of hard compacted material and blasted rock in mining or quarry applications, where high break-out force is required. Severe digging is no problem for this tough bucket, made entirely of highly wear-resistant steel with a hardness of 420 BHN. Weld-on ESCO® teeth come standard.

Log grabs

Log grabs are designed to handle easily and safely all kind of trunks for forestry applications. Available with different configurations, they are manufactured of hardened steel to endure high stress.
