DOOSAN has launched the third model in the manufacturer’s new high reach demolition excavator range.
The DX380DM-7 joins the DX235DM and DX530DM machines, which were introduced last year.
Operating from a tiltable cab on the DX380DM-7, Doosan revealed that operators have an environment particularly suited to high reach demolition applications, with a 30 degree tilting angle. The maximum pin height of the demolition boom is 23m.
The DX380DM-7 retains a hydraulically adjustable undercarriage, which extends to a maximum width of 4.37m. The width of the undercarriage can be retracted hydraulically to 2.97m in the narrow width position, for transporting the machine. Doosan added that 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’.
Safety features include a FOGS cab guard, safety valves for the boom, intermediate boom and arm cylinders, and a stability warning system.
In common with the other models in the high reach range, the DX380DM-7 has a modular boom design and hydraulic lock mechanism. This, Doosan explained, facilitates an easy change between a demolition and an earthmoving boom for different types of work on the same project.
The multi-boom design also allows the earthmoving boom to be mounted in two different ways, providing 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 DX380DM-7 can work to a maximum height of 10.43m.
