Allu Launches New Concrete Bucket to Advance On-Site Crushing and Screening of Demolition Materials
ALLU, a Finnish manufacturer of material processing attachments, recently announced the launch of the ALLU Concrete Bucket, a new excavator attachment designed to crush and screen pulverized demolition concrete directly at the point of demolition. The new solution enables contractors to process demolition materials where they are generated, helping improve workflow, reduce unnecessary transportation, and support more efficient material recovery across demolition and recycling projects. As construction and demolition industries continue to prioritize operational efficiency and sustainable material management, contractors are increasingly seeking equipment that minimizes handling while maximizing the value of recoverable materials. Demolition sites commonly produce large volumes of mixed waste, including pulverized concrete, reinforced concrete, brick, asphalt fragments, soil, and steel contamination. Processing these materials on-site can reduce hauling requirements, simplify logistics, and allow reusable aggregates to be produced more efficiently for future construction applications. The ALLU Concrete Bucket has been developed to address these operational challenges by allowing contractors to crush and screen demolition material using the excavator already operating on the jobsite. Rather than transporting debris to a secondary crushing facility or bringing in additional processing equipment, operators can complete material processing directly where demolition activities are taking place. This approach can improve productivity while reducing equipment movements and supporting more streamlined project execution, particularly on urban projects or locations where available space is limited. Designed for excavators in the 25- to 45-t operating class, the ALLU Concrete Bucket accepts feed material measuring up to 300 mm and produces finished aggregate in either 0-50 mm or 0-100 mm sizes, depending on the selected counter blade configuration. Under suitable operating conditions, the attachment is capable of processing as much as 100 t of material per hour, providing contractors with a practical solution for handling large volumes of demolition waste while reducing reliance on off-site processing. Unlike conventional jaw crusher systems, the ALLU Concrete Bucket utilizes rotating drums equipped with replaceable carbide picks working together with a counter blade structure to crush and screen material continuously. This design promotes a consistent material flow while reducing oversized concrete into reusable aggregate suitable for recycling, backfilling, road construction, and other civil engineering applications. The rotating drum technology has been developed to withstand demanding demolition environments while providing reliable performance throughout extended operating periods. Replaceable wear components allow routine maintenance to be completed directly at the jobsite, helping contractors minimize downtime and keep equipment in service without lengthy interruptions. Compatible carriers can also utilize ALLU's Drain Line Eliminator™ hydraulic technology, further simplifying installation and improving operational efficiency. The ALLU Concrete Bucket is designed for processing pulverized demolition concrete, reinforced concrete, brick, asphalt fragments, demolition rubble, and other mixed construction materials commonly generated during demolition projects. By combining crushing and screening functions into a single attachment, the new solution provides contractors with greater flexibility while reducing the need for additional processing equipment on-site.
