Doosan's North American waste handling effort

07 October 2014

The first of the three new Doosan handlers launched in North America is the DX225MH-3 material handler. It was joined by the tracked DX300MH-5 and a wheeled model, the DX210WMH.

According to Doosan, material handlers are not new to the company, but this is the first time Doosan is building machines specifically designed for material sorting and handling applications. In the past, dealers converted the company’s tracked or wheeled excavators into material-handling machines in response to specific customer requirements.

Built for the job

Doosan material handlers were developed to meet the demands of material handling professionals by dedicated, in-house product engineering support. Each is based on a proven and tested excavator model that has been factory fitted with cab risers for increased visibility, a straight boom and droop nose arm for optimal performance and improved machine guarding for maximum uptime. Straight booms improve reach and lift height for better material placement, while droop nose arms provide good grapple clearance and enhanced access into containers, trucks and railcars. Features such as dual-boom cylinders and under-mount arm cylinder placement provide excellent lifting capabilities, says the company.

Another commonly recognised material handler feature is the cab riser that provides operators with better all-around visibility to the attachment and work area from the material handler’s cab riser. Standard fixed risers for the DX225MH-3 are 1.2 m (4 ft), and 1.8 m (6 ft) for the larger DX300MH-5. A 1.8 m fixed riser is also available as an option for the DX225MH-3.

Fixed risers can easily be lowered for transport with a self-contained, electronically powered hydraulic system. Available as an option for the DX225MH-3 and DX300MH-5 is a 2 m (6.5 ft) hydraulic cab riser. The 2 m hydraulic cab riser is fitted as standard equipment for the wheeled DX210WMH.

Tailored power

Four power modes are available on the Doosan DX225MH-3 and DX300MH-5 to help operators manage the balance of fuel consumption and machine power to the working conditions. The four selectable power modes include: Power+ mode that delivers the fastest work group speeds and greater power for those high demanding material moving applications; Power mode that provides exceptional power and superior performance for tough heavy lifting, quick truck loading and fast travel speed; Standard power mode that enhances the machine’s fuel consumption while delivering high performance in everyday lifting and moving of material and finally Economy mode that helps reduce fuel consumption for low-demand applications and slows down machine movement for conditions that require more precise movements

The DX210WMH is available with three selectable power modes, namely Power, Standard and Economy.

In addition to the power modes, the Doosan DX225MH-3 and DX300MH-5 material handlers have a lifting work mode that provides increased pump torque, low engine rpm and an automatic power boost.

Telematics is standard for all three Doosan material handlers and comes with a three-year subscription. The system provides location information and a full range of machine operational information to owners, their dealer and Doosan. Information is provided through a simple user interface, accessible online via a web-enabled computer or smartphone. The goal is to help owners monitor their equipment and manage maintenance to reduce operating costs.

Grapple attachments

To maximise their versatility and productivity, the new material handlers can be paired with a grapple for material handling applications. The 360-degree hydraulic rotating four-tine grapples feature a semi-closed tine design, allowing a firm grasp on most materials. The tines are designed with AR400 high-strength, abrasion-resistant steel for increased durability, and the tine tips are replaceable for easier maintenance.

A 0.5 cubic metre (17 cubic foot) grapple is approved for use with the DX210WMH and the DX225MH-3, while a 0.8 cubic metre (27 cubic foot) grapple is approved for use with the DX300MH-5 with grapple connection to the new machines being rapid and easy through the use of a hose kit and mount.
