for fewer machines, fewer material movements, and better utilisation of the equipment they already own.” Looking beyond purchase price For ALLU, return on investment needs to be considered across the complete material-handling process rather than simply comparing the purchase price of one attachment with another. “If one carrier can excavate material and then screen, crush, mix or load it using an attachment, there may be less need for additional machinery, operators and transport,” says Grönholm. Versatility also affects utilisation. An attachment that can be deployed across different projects and applications has the potential to be used more frequently than equipment designed for a single task. There is a further benefit when material previously regarded as waste can be processed and reused on the same project. This can reduce disposal costs while limiting the need to purchase replacement material. “That combination of productivity, utilisation and fewer processing steps is where the economics of the attachment become particularly interesting,” says Grönholm. Customers are increasingly considering this broader total cost of ownership when evaluating equipment, with payback becoming an important consideration. “With screening buckets, the savings can add up fast,” says Rautamies. “Processing material on site can reduce fuel use, transportation and disposal costs, while also cutting the need to buy new aggregates by allowing existing material to be reused.” New developments for wider use A major recent development is the ALLU Concrete Bucket, which combines crushing and screening in an excavator-mounted attachment for demolition and recycling. Designed for 25–45-tonne excavators, the bucket can accept demolition material up to 300 mm. Under suitable material and operating conditions, processing capacity can reach up to 100 tonnes per hour. Output can be configured for either 0–50 mm or 0–100 mm material, while the bucket is designed to handle demanding feed containing fines, brick, and steel such as rebar. “Contractors don’t need another machine to manage on a crowded jobsite; they need a practical way to turn rubble into usable material with the excavator they already have,” says Rautamies. “This
