Top-of-range excavator takes down historic factory

24 November, 2022

The contract for the demolition was awarded to Seli Manutenzioni Generali Srl of Monza, a company with over 50 years of experience in the construction sector, which has seen significant growth in its recently formed Business Unit dedicated to demolition and decommissioning.

The company’s DX530DM, the largest demolition excavator produced by Doosan, with a 29 m boom and a truly impressive working range, was the ideal machine for a contract of this magnitude. Like all Doosan demolition excavators, the DX530DM is particularly flexible, allowing the demolition arm to be swapped for an excavation arm and vice versa, thus making it possible to perform different jobs on the same site, with the same machine 

All Doosan demolition excavators are also equipped with a unique high visibility cab that tilts by up to 30 degrees, specifically designed for these high reach applications. Another important feature is the extendable undercarriage which guarantees optimal stability, which is essential on sites of this magnitude. The undercarriage width can be reduced hydraulically to make transport easier.

The DX530DM equipped with a long arm and demolition grapple, carried out the entire demolition from above of two industrial buildings consisting of a tower section, 20 m high, and two single-storey buildings, that made up the old OEB factory.

Surgical precision

The DX530DM excavator, customised in the white and yellow colours that distinguish the Seli Manutenzioni Generali fleet, made it possible to perform a demolition that overcame the problems involved, ensuring surgical precision in completing the work in just eight working days.

The demolition work carried out with the DX530DM demolition excavator was continuously supported by a Doosan DX235LCR-7 excavator which, in alternating phases, dealt with the crushing and removal of steel from the demolition waste, as well as the subsequent loading of materials onto trucks destined for recycling plants.

The use of the most modern and innovative equipment has guaranteed an extremely reduced environmental impact, both in terms of noise and dust emissions, allowing to minimize the disturbance caused to the residents in the area and the district’s commercial activities and services, limiting vibrations and noise propagation, for the entire duration of the demolition phases.
