DOOSAN has introduced the new DX245DM-7 high reach demolition excavator.
The 31-tonne machine replaces the previous DX235DM-5 model. Powered by the Doosan DL06P Stage V diesel engine providing 129 kW (173 HP) of power at 1800 RPM, the digger is part of a range of demolition machines that also includes the 47-tonne DX380DM-7 and 61-tonne DX530DM-7.
Doosan revealed the DX245DM-7 has a ‘high visibility, tiltable cab’, and is said to be particularly suited to high reach applications. It offers a 30 degree tilting angle.
Other features include a modular boom design and hydraulic lock mechanism. This provides the flexibility to use the same excavator for other applications on site as well as demolition.
Doosan added that the design ensures a ‘simple process’ to change between demolition and earthmoving boom to accomplish different tasks on the same project. 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.
When equipped with the 18m long demolition boom, the working range allows the machine to work with a demolition attachment to a maximum height of 16m. The recommended maximum combined weight for the attachment and quick coupler in this mode is 2.5-tonne.
When equipped with the digging boom in the straight configuration, the DX245DM-7 can work to a maximum height of over 9.8m. Here, the recommended maximum weight for the attachment and quick coupler is 3.3-tonne.
Using the digging boom in the alternative bent configuration, the model can work with an attachment to a maximum height of 8m. In this mode, the recommended maximum weight for the attachment and quick coupler is 3.3-tonne.
A hydraulically adjustable undercarriage extends to a maximum width of 3.74m. The width can be retracted hydraulically to 2.54m in the narrow width position.
Safety features include a FOGS cab guard, safety valves for the boom, intermediate boom and arm cylinders, and a stability warning system.
