ALLU, Pennala, Finland, debuted its concrete bucket during CONEXPO-CON/AGG 2026 and officially launched the ALLU Concrete Bucket, a new excavator attachment designed to crush and screen pulverized demolition concrete directly at the point of demolition, in July. 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.
Designed for excavators in the 25- to 45-tonne operating class, the ALLU Concrete Bucket accepts feed material measuring up to 11 inches (300 millimeters) and produces finished aggregate in sizes of either 0-2 inches (0-50 millimeters) or 0-4 inches (0-100 millimeters), depending on the selected counter blade configuration. Under suitable operating conditions, the attachment is capable of processing as much as 100 tonnes of material per hour, according to the manufacturer.
The attachment has also been engineered to perform effectively in reinforced concrete applications where steel contamination is commonly encountered. During operation, reinforcing steel and rebar can pass through or be separated as materials are processed, helping maintain continuous production. This capability allows contractors to process a wider range of demolition materials without compromising productivity.
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. Replaceable wear components allow routine maintenance to be completed directly at the job site, 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.
