The CDS 20 screening bucket: simple, but highly productive

The CDS 20 screening bucket in the environmental redevelopment for the creation of an urban forest in Schio

In the Municipality of Schio (VI), between the parking lot of via Milano and via Istria, an important urban regeneration project has begun. Thanks to the funds made available by the “Area Urbana Pedemontana” project, a new urban forest is being created as part of the “Nature-based Schio Solutions” initiative. The project involves the planting of approximately 200 trees in strategic parking areas. Urban greenery will increase significantly thanks to the planting in the areas used for parking, contributing to preventing the formation of heat islands in populated areas. In addition to improving thermal comfort, the trees will have a positive impact on air quality thanks to the absorption of CO₂ and the reduction of pollutants.

PRODUCTIVITY AND DETERMINATION

Before proceeding with the tree planting, the area required thorough remediation. It was in fact, an abandoned area invaded by wild vegetation, thick bushes, and waste hidden by the vegetation, such as plastic, tires, and building debris accumulated over the years. The work was entrusted to the Dal Maistro company of Monte di Malo (VI), already a CM customer for over a decade and specialized in construction and environmental remediation work.

To separate the soil from the waste and prepare it for the leveling necessary for the new planting, a CM CDS 20 rotor screening bucket was used, with a distance between the discs of 30 mm. The choice fell on this model for its versatility, as it is suitable for both large excavators such as the Hitachi ZX300, and lighter machines such as the Hitachi Zaxis 210 LCH, used specifically for this work.

Equipped with four rotors, the CDS 20 guarantees high output even on difficult materials and in demanding conditions. The rotors in Hardox 450 guarantee high wear resistance and long life; the front and rear scrapers fitted as standard facilitate the self-cleaning of the rotors.

On the construction site in question, the CDS 20 screening bucket diligently separated the waste of building material accumulated over the years from the earth, then finely sieved it to prepare the ground for future planting.

Furthermore, with the CDS series, the rotors can be changed to apply discs also suitable for light shredding, thus expanding its functionality.
