New Doosan DX235DM Demolition Excavator on Milan Project


A new Doosan DX235DM demolition excavator has proved to be the ideal machine for the 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). 

Founded in the 1960s, Seli is a well-established company specialising in the construction of civil and industrial buildings. The sale of the Doosan DX235DM at Seli was organised by Gabriele Silvagni, the founder, president and administrator of DMO and Gianmaria Lupis, DMO sales manager for Lombardy. The two businesses have built a successful commercial relationship and Seli has chosen DMO to be the company’s main supplier for the rental and sale of earthmoving machinery. In addition to the DX235DM, Seli also purchased a new Doosan DX530DM demolition excavator and two conventional Doosan DX235LCR-5 and DX340LC-5 excavators as part of the deal. 

Seli is structured into four Business Units – Construction, Finishing, Plant and Demolition/Excavation – each of which is managed by a technical manager with proven experience in each sector. The most recent Business Unit is Demolition/Excavation, which has recruited several engineers and Ivano Perego as Sales Manager. Since October 2019, this division has won important orders, particularly in Milan and its province, a market for which the Doosan DX235DM is very suitable.

“The machine stands out for its great flexibility in terms of application and speed,” said Riccardo Cucini, Technical Director and Production Manager at Seli. “We chose the Doosan DX235DM because it is the only demolition machine that can be transported on the road without the need for exceptional transport and related special permits. Another reason for the purchase is the excellent stability of the machine thanks to the quick-acting, hydraulically adjustable undercarriage.”

DX235DM Maximum Efficacy and Versatility

The hydraulically adjustable undercarriage is one of the key features of the DX235DM, allowing it to be expanded to a maximum width of 3.74 m for optimal stability in demolition operations, with the ability to hydraulically retract the width to 2.54 m, 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 innovative design ensures it is a simple process to change between an 18 m 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 tonne.   

Using the digging boom in the alternative bent configuration, the DX235DM can work with an attachment to a maximum height of 8 m. In this mode, the recommended maximum weight for the attachment and quick coupler is again 3.3 tonne.    

The success at Seli signals a very promising outlook for future sales of the Doosan demolition excavators throughout Italy, both for the DX235DM and the other two models in the range, the DX380DM and the DX530DM.For more on Doosan construction equipment, please visit the website:
