Doosan launches new top-of-the-range demolition excavator

South Korean vehicle manufacturer Doosan has expanded its high reach demolition excavator range with the announcement of the new top-of-the-range DX530DM model. The third machine in the range, the DX380DM will be launched in the first half of next year.

Increased flexibility

Like the Doosan DX235DM demolition excavator launched earlier this year, the DX530DM provides increased flexibility with a modular boom design and hydraulic lock mechanism. This innovative 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 DX530DM also retains a hydraulically adjustable undercarriage, which extends to a maximum width of 4.37 m to provide optimum stability when working on demolition sites. The width of the undercarriage can be retracted hydraulically to 2.97 m in the narrow width position, for transporting the machine. 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.

The maximum pin height of the demolition boom on the DX530DM is 27.5 m, compared to 18 m on the DX235DM. The impressive working range on the DX530DM allows the machine to provide a maximum reach of 16.5 m with a 3 tonne tool.

These features are again combined on the DX530DM with a high visibility, tiltable cab, particularly suited to high reach demolition applications and offering a 30 degree tilting angle.

Multi-boom design offers three different configurations

The multi-boom design 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.

When equipped with the digging boom in the straight configuration, the DX530DM can work to a maximum height of 13.5 m. Using the digging boom in the alternative bent configuration, the DX530DM can work with an attachment to a maximum height of just over 11 m.

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.

On all 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.
