Doosan adds third model to series of demolition excavators

Impressive demolition specifications

The operator can work from a tilting cab with excellent visibility. This machine is very suitable for demolition work due to its long reach with a 30-degree tilt angle. The maximum pen height that sits on the boom of the DX380DM-7 is 23 meters.

The Doosan DX380DM-7 also has a hydraulic adjustable undercarriage that extends to a maximum width of 4.37 meters to provide optimum stability. The width of the undercarriage can be hydraulically extended and retracted to a minimum length of 2.97 meters. This so that the machine can be properly transported. Automatic lubrication of the extension and retraction system in the cylinder design minimizes resistance during this movement and helps prevent damage to components.

Like all Doosan demolition excavators, the DX380DM-7 is equipped with all standard safety features such as a FOGS cab guard, safety valves for the boom, intermediate boom and arm cylinders and a stability warning system, among others.

Multi-boom design for greater flexibility

Like the other models in the High-Reach series, the DX380DM-7 offers more flexibility with a modular boom design and a hydraulic locking mechanism. This innovative design makes it easy to switch between a demolition boom and an earthmoving boom so you can do different types of work on the same project with the same machine.

The multi-boom boom design allows an earthmoving boom to be mounted to the machine in two different ways, giving you more flexibility with a total of three different configurations for the same machine.

There is a special stand to facilitate the changing of the boom which ensures that you can quickly change and couple the booms. A system which is based on a cylinder system which ensures that the locking pins are pushed into place to complete the change.

When equipped with an excavator arm, the DX380DM-7 can work up to a maximum height of 10.43 meters.
