Impressive new features available on Doosan machines

Winter 2013

Doosan continues to deliver an impressive selection of heavy equipment with the launch of several new excavators — crawler and wheel — and wheel loaders featuring numerous system and performance improvements. Advancing product lines beyond the delivery of interim Tier 4 (iT4) compliance, Doosan evaluated markets and listened to customers about what they need to be more productive. The results are exceeding customer expectations.

Crawler excavators

Continuous improvements and updates to Doosan excavators provide operators with more power, performance and speed. New Doosan iT4-compliant machines have also been upgraded to allow operators to customize the excavator to a variety of working conditions found in rental, site development, commercial construction and highway/street development applications.

Updated Doosan excavators are equipped with a new electronic fan clutch, reducing fuel consumption and noise levels, while providing cooling system efficiency improvements on the machines. Newer Doosan excavators also include an Electronic Power Optimizing System (EPOS), four power modes, four work modes, auto idle and machine diagnostics. Operators can work more effectively with multiple work modes, easy-to-read display monitors and precise control levers. The new Power+ mode provides improved performance and faster workgroup speeds for heavy-duty work.

Four work modes — digging, lifting, breaker and shear — allow operators to get maximum efficiency and fuel economy in specific applications. In the lifting mode, the increased pump torque, low engine RPMs and automatic power boost provide extra muscle when lifting materials like pipe or concrete barriers.

Intelligent Floating Boom

A new Intelligent Floating Boom option allows the boom of the Doosan excavator to "float" up or down, letting the operator focus more on the task while decreasing the machine workload and increasing efficiency.

Straight travel, increased speed

A new straight travel option streamlines the travel and transport of the Doosan excavators. This feature is ideal for the straight forward and backward travel, which is common in trenching applications. It provides a single foot pedal in the right front corner of the cab floor that operates both tracks. Additionally, the new machines provide speed improvements, offering more efficient movement around jobsites.

Enhanced operator comfort

Doosan continues to focus on operator comfort with further enhancements to the Roll-Over Protective Structure (ROPS) cabin. The door window position slider now locks in various positions, preventing it from moving from its intended location. The door space of the cab has increased by 1.8 inches, allowing the operator to get in and out more easily. The cabin size has increased 6.1 percent, providing more headroom. The joystick angle has been reduced from 25 degrees to 19 degrees to provide a more ergonomic profile and decrease interference with operators' legs.

Additional cab updates include both a height lever and tilting function for the air suspension heated seat to allow the operator to find an optimum seating position. The cabin mounting mechanism has been improved with a thickened dampening plate, and an internal coil spring has been added to reduce cabin vibration 20 percent, allowing operators to work longer days with less fatigue.

Wheel excavators

DX140W and DX190W

The DX140W-3 and DX190W-3 wheel excavators combine increased power and performance with iT4 updates, enhancing their ability to complete highway and street development and site development projects, as well as have an impact in dealer rental fleets. The DX190W-3 is also suited for scrap handling and sewer and water work. Like the new crawler excavators, these updated wheel excavators also offer a new electronic fan clutch and Electronic Power Optimizing System with four work modes.

Outrigger control

Outriggers can be controlled individually to level the machine on uneven surfaces. The front axle oscillates and provides excellent steering angles for maneuverability, but can be locked for better digging and lifting performance.

New Doosan wheel loaders enhance performance and operator comfort

Updated Doosan wheel loaders feature improvements in performance, serviceability and operator comfort.

Performance updates

Equipped with an interim Tier 4 compliant (iT4) diesel engine, new Doosan wheel loaders have increased horsepower and lift capabilities for enhanced performance, helping operators get more work done in less time. Newer Doosan wheel loaders are also more fuel-efficient, helping owners reduce costs and improve profits.

A hydraulic locking differential is available as an option to the standard limited slip differential. The optional hydraulic locking differential may be locked manually or automatically, based on ground conditions.

Newer Doosan wheel loaders are equipped with auto idle for additional noise reduction and fuel savings. The feature reduces the working idle of the wheel loader by 200 rpm when the machine is inactive for a short period of time. Conversations between the wheel loader operator and other employees are much simpler, thanks in part to auto idle.

Doosan wheel loader operators have the ability to set upper and lower limits for the lift arm stop positions from inside the cab rather than setting them outside. This feature is great for working in height-restricted structures (setting max. height) or repetitive tasks such as truck loading to increase productivity.

Another common option for select Doosan wheel loaders is a torque converter lockup clutch. This enables the machine to climb grades easier and faster, increasing productivity as much as 20 percent in certain stockpiling applications.

More new options for Doosan wheel loaders include a diesel-powered coolant heater to improve starting in cold weather or a block heater that warms the engine coolant before engine startup with an electrical heater.

Serviceability

Properly maintaining equipment ensures its longevity. That's why Doosan wheel loaders have easy-to-access routine service items, such as fluids and filters, to help owners and operators perform daily maintenance checks.

The new automatic reversing cooling fan can be set to run in reverse to assist in keeping the cooling system clean. The operator can reverse the fan by activating a switch, or it can be set to automatically reverse on a preset time frame. This is particularly helpful in agriculture applications where hay and other debris can quickly build up in the cooling system.

Enhanced comfort

Interior cabin improvements also include a number of multi-function display panel upgrades on a centralized monitor that allow the operator to view comprehensive machine system information ─ such as engine rpm, engine coolant temperature, fuel level, DEF level, machine warnings, time and the transmission selected gear.

Operators can quickly glance at all key switches with the application of a window decal containing all switch icons, and description of their function. A vital exterior cabin improvement is lowered front-side glass, providing improved visibility of operations.

With a focus on increasing cab comfort for operators, optional electric steering decreases operator fatigue during repetitive cycle operations on the jobsite. A joystick has been added to the left armrest that allows the operator to control the directional movement without having to use the steering wheel. A new door threshold makes getting in and out of Doosan wheel loaders — and cleaning the inside of the cab — much easier.
