Allu Combines Concrete Screening and Crushing in One Bucket

Why It Matters

By turning a standard excavator into a on‑site crusher, contractors can cut equipment costs, reduce haul‑away time, and accelerate recycling of concrete and brick waste, reshaping demolition economics.

Key Takeaways

• Processes up to 100 tonnes per hour on‑site
• Handles rebar without stopping work
• Fits 25‑45 ton excavators, no extra machine
• Adjustable output size 50‑100 mm for flexibility

Pulse Analysis

Allu's new concrete bucket reflects a broader shift toward integrated demolition equipment that maximizes productivity on space‑constrained job sites. Traditional demolition workflows often require a separate mobile crusher, adding transport logistics, fuel consumption, and rental expenses. By mounting a crusher and screen directly onto an excavator, Allu eliminates these bottlenecks, allowing crews to crush, screen, and load material in a single pass. This approach not only reduces equipment footprints but also shortens the time between demolition and material reuse, aligning with tighter project schedules and sustainability mandates.

The bucket’s engineering tackles one of the toughest challenges in demolition: rebar‑laden concrete. Rebar can jam conventional crushers, causing costly downtime. Allu’s design incorporates a heavy‑duty frame, 40 mm cutting edge, and dual‑direction rotating drums that keep material moving while separating fines through the bucket. With a hydraulic flow requirement of 190‑315 L/min and power draw of 80‑134 hp, the attachment fits within the capabilities of most mid‑size excavators, delivering up to 100 tonnes per hour without excessive fuel penalties—approximately 30 L/h on a 40‑ton machine.

Industry analysts see this development as a catalyst for faster, more circular construction practices. By enabling on‑site reduction of concrete, brick and asphalt, contractors can feed material directly into recycling streams or reuse it for backfill, lowering landfill disposal fees and carbon footprints. As municipalities tighten waste‑diversion regulations, tools like Allu’s bucket give demolition firms a competitive edge, positioning them to meet both cost pressures and environmental targets while expanding the market for compact, multi‑function attachments.
