Doosan adds DX530DM to its demolition excavator rangePublished 2/12, 2020 at 13:59
Doosan has expanded the company’s ‘High Reach Demolition Excavator’ series with the launch of the new top of the range DX530DM model, with its third machine, the DX380DM, set to be launched in the first half of 2021.
Like the Doosan DX235DM demolition excavator, the first model in the range launched earlier in 2020, 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 4.37m to provide optimum stability when working on demolition sites. The width of the undercarriage can be retracted hydraulically to 2.97m 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 27.5m, compared to 18m on the DX235DM. The impressive working range on the DX530DM allows the machine to provide a maximum reach of 16.5m with a 3t 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 30o tilting angle.
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 13.5m. Using the digging boom in the alternative bent configuration, the DX530DM can work with an attachment to a maximum height of just over 11m.
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. As with all Doosan demolition excavators, the new machine has standard safety features including a FOGS cabin guard, safety valves for the boom, intermediate boom and arm cylinders and a stability warning system.
