Demolition excavator at work in Milan

A new Doosan DX235DM demolition excavator has proved to be the ideal machine for company, Seli Manutenzioni Generali Srl of Monza, for demolition work at the historic Catholic University del Sacro Cuore in the centre of Milan in the Lombardy region of Italy. Using the DX235DM, Seli has carried out demolition work on a building at the university as part of a redevelopment project for new teaching rooms at the institution. 

The DX235DM is part of a new range of high reach demolition excavators launched by Doosan to meet growth in the demolition market both in Italy and throughout Europe. The machine in Milan was purchased from DMO, the Authorised Dealer for Doosan and Bobcat for the regions of Emilia Romagna, Veneto, Friuli Venezia Giulia and Lombardy (the provinces for Milan, Cremona, Mantua, Lodi, Pavia, Varese, Monza and Brianza).

The hydraulically adjustable undercarriage is one of the key features of the DX235DM, allowing it to be expanded to a maximum width of 3.74m for optimal stability in demolition operations, with the ability to hydraulically retract the width to 2.54m, ideal when transporting the machine. The hydraulic width adjusting mechanism works very quickly and uses a permanently lubricated internal cylinder which minimizes resistance during movement. Typical of the design of the new Doosan demolition machines, the DX235DM has a high visibility, tiltable cab, particularly suited to high reach demolition applications and offering a 30-degree tilting angle.

Another key feature of the DX235DM, which is shared with the other models in the new High Reach Demolition Excavator range from Doosan, is a modular boom design and hydraulic lock mechanism on the machine. This provides the customer with a complete, flexible solution that allows them to use the same excavator for other applications on site as well as demolition. The design ensures it is a simple process to change between an 18m demolition boom and an earthmoving boom (available in two different configurations) to accomplish different types of work on the same project.

When equipped with the digging boom in the straight configuration, the DX235DM can work to a maximum height of 9 m. In this format, the recommended maximum weight for the attachment and quick coupler is 3.3 tonnes. Using the digging boom in the alternative bent configuration, the DX235DM 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 again 3.3 tonnes. The DX235DM is partnered by two other demolition excavators in the range: the DX380DM and the DX530DM.
