Doosan | More speed less waste

Doosan | More speed less waste

Doosan has completed its demolition and material handler lines with a number of new additions to the range 

As a manufacturer, Doosan can now comfortably cover most applications in the demolition, waste and recycling industries. Indeed, whether it’s in materials handlers or excavators, a number of industry specific features – such as the high visibility tiltable cab with a 30 degree tilting angle found in the latter – has made these machines an increasingly popular choice amongst the sector’s operators.  

The newly launched DX380DM-7 High Reach Demolition Excavator joins the existing DX235DM-5 and DX530DM-5 models introduced last year. These are complemented by the company’s new range of Material Handler models which now comprises three units – the wheeled DX230WMH-5 and DX250WMH-5 and the tracked DX225MH-5.  

Increased flexibility
All three High Reach machines provide increased flexibility, with a modular boom design and hydraulic lock mechanism. This design facilitates an easy change between a demolition boom and an earthmoving boom to accomplish different types of work on the same project, using the same machine. The multi-boom design also allows the earthmoving boom to be mounted in two different ways which, with the demolition boom, provides further flexibility with a total of three different configurations for the same base machine.

A special stand is provided to facilitate the boom changing operation, which is based on quick-change hydraulic and mechanical coupler connections. A cylinder-based system is used to push the locking pins into place to help complete the procedure. 

When equipped with the demolition boom, the maximum pin height is 18, 23 and 27.5 m on the DX235DM-5, DX380DM-7 and DX530DM-5, respectively. When equipped with the digging boom in the straight configuration, the DX235DM-5, DX380DM-7 and DX530DM-5 can work to maximum heights of 9.0, 10.43 and 13.5 m, respectively. 

Hydraulically adjustable undercarriage
All three models share a hydraulically adjustable undercarriage, which extends to a maximum width to provide optimum stability when working on demolition sites. In transportation, the width of the undercarriage can be retracted hydraulically to a narrow width position. The adjusting mechanism is based on a permanently lubricated, internal cylinder design which minimises resistance during the movement and helps to prevent damage to the components.  

On all the Doosan demolition excavators, standard safety features include a FOGS cabin guard, safety valves for the boom, intermediate boom and arm cylinders and a stability warning system.

Three new material handlers
The 23 tonne DX230WMH-5 and DX250WMH-5 25 tonne wheeled machines are based on the Korean manufacturer’s popular DX210W-5 wheeled excavator. The DX225MH-5 25 tonne crawler model is based on Doosan’s successful DX225LC-5 22 tonne excavator and the crawler type undercarriage is particularly suited for work in difficult ground conditions.

All three have been designed specifically for a wide range of material sorting and handling applications such as those in the scrap metal and other solid waste and recycling industries, as well as demolition, forestry and logging.

Designed to carry out the toughest tasks, the DX230WMH-5 and DX250WMH-5 are built with front and rear stabilizers, and a boom and arm specifically designed for material handling tasks. A standard feature is the hydraulic cab riser, which gives the operator better all-around visibility of the attachment and work area. When combined with the rear view camera display in the cab, the operator has excellent visibility of the job site.

The maximum pin heights on the DX230WMH-5 and DX250WMH-5 are 11.7 m and 12.0 m, the maximum operating reaches are 10.1 m and 10.7 m and the maximum working depths are 4.2 m and 4.7 m, respectively.

The DX225MH-5 is equipped with factory-fitted material handling features such as a 2.5 m elevating cab, a 6.5 m straight boom and a 4.5 m droop nose arm, a counterweight, grapple-ready hydraulics and additional guarding. The maximum pin height in the DX225MH-5 is 11.7 m, the maximum operating reach is 10.6 m and the maximum working depth is 5.2 m. The DX225MH-5 has two arm cylinders for extra balance and more stability and lesser movement when using attachments such as grapples.

The new DX230WMH-5 and DX250WMH-5 are powered by the 6-cylinder, turbocharged Doosan DL06PA water-cooled diesel engine, providing an output of 129.4 kW (173.5 HP). The new DX225MH-5 material handler is powered by the 6-cylinder, turbocharged Doosan DL06K water-cooled diesel engine, providing an output of 124 kW (166 HP). 

An optional generator is available as a turnkey solution without requiring additional modification. For added durability, an optional V-guard protects the machine sides and components behind the doors.

Doosan can also provide a range of options, such as gooseneck and straight arms, solid tyres and FOGS as well as different attachments to match customers’ applications and to enhance productivity, for a wide range of material sorting and handling applications. There are a number of factory installed options for the material handlers, including the following:

  • Additional work lamps
  • Cab guarding
  • Frame guards
  • Fuel filter pump
  • Rotating beacon
  • Solid tyres
  • Air compressor
  • Double pump flow
  • Rubber track pad

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