The new ALLU Concrete Bucket helps contractors crush and screen pulverized demolition concrete directly on urban jobsites.
Concrete is everywhere around us. It is in the roads we drive on, the buildings we work in, and the infrastructure that keeps cities moving. But when those structures reach the end of their life, the question becomes very practical: what happens to all that concrete?
For demolition, recycling, and construction contractors, concrete waste is not just a sustainability topic. It is a daily jobsite challenge. Pulverized demolition concrete is heavy, irregular, and rarely clean. It can include brick, fines, oversize pieces, dirt, rebar, and other steel objects. On urban sites, where space is limited and every machine movement matters, handling that material can quickly become expensive.
That is exactly the kind of challenge the new ALLU Concrete Bucket is built to solve.
The ALLU Concrete Bucket is an excavator-mounted crushing and screening attachment designed to process pulverized demolition concrete, concrete rubble, bricks, and large asphalt fragments directly where the material is generated. At 2,500 kg / 5,500 lbs, the bucket is a relatively light attachment, giving operators more reach and minimizing movements at the jobsite. Instead of moving bulky rubble around the site before it can be reused, transported, or processed further, contractors can bring the processing power straight to the pile.
In simple terms: crush and screen the material where it lands.
Designed for pulverized demolition concrete
The ALLU Concrete Bucket is made for pulverized demolition concrete: the kind of tough, mixed material contractors face after slabs, foundations, walls, industrial floors, or other concrete structures have been broken down.
It accepts feed material up to 300 mm / 11in and can produce either a 0–50 mm or 0–100 mm / 0–2 in or 0–4 in output, depending on the selected counter blade setup. This gives contractors flexibility depending on what the job needs. Some sites may require a finer fraction for easier reuse or transport, while others may benefit from a coarser, higher-flow product.
In suitable material and conditions, the bucket can process up to 100 t/h / 220,000 lbs per hour. As always in real jobsite applications, the final capacity depends on the material, carrier machine, operator, and site conditions — but the goal is clear: keep material moving and reduce unnecessary handling.
Heavy-duty structure, practical attachment format
The ALLU Concrete Bucket is designed for 25–45 tonne / 55,000–94,000 lbs excavators, placing it in the working range for demanding demolition, recycling, and heavy construction applications.
At 2,500 kg / 5,500 lbs, it gives contractors a serious processing tool in an attachment format. The structure includes a heavy-duty frame with a 40 mm / 1.6in cutting edge and 30 mm / 1.2in side cutters, designed to withstand the breakout forces of excavators up to 45 tonnes / 94,000 lbs.
The bucket also uses replaceable carbide picks, built for tough and abrasive demolition work. Together with the Variable Drum design, these wear parts are designed for practical replacement, helping contractors keep maintenance straightforward on demanding jobsites.
The rotating drums and counter blade design make processing the rubble faster. Fines-heavy material can pass through quickly, while larger pieces are reduced against the counter blade structure. The top and middle drums are configured to crush the material towards the top crushing blades, while the bottom drum is configured the opposite. This design enables crushing the material with both rotating directions, resulting in an optimal material flow that keeps the job going forward.
ALLU has also added its Drain Line Eliminator™ technology, which helps simplify hydraulic setup on suitable carriers by removing one common hydraulic connection obstacle. For contractors and rental fleets, that can mean easier attachment use across compatible machines.
Rebar in the mix? Ready for it.
One of the biggest issues in concrete demolition is steel contamination. Rebar and other steel objects can quickly slow down processing when the equipment is not designed for real demolition feed.
The ALLU Concrete Bucket is designed to handle rebar and other steel objects mixed in the material. This helps reduce stop-and-clear interruptions and keeps the excavator productive in conditions where the feed material is not clean, uniform, or perfectly prepared.
For contractors, that matters. Real demolition concrete does not arrive neatly sorted. It comes with surprises. The bucket is built for that reality.
Helping contractors respond to the growing concrete waste challenge
The scale of concrete and construction waste is increasing the pressure on contractors, recyclers, and cities to handle material more efficiently. More concrete in use eventually means more concrete to demolish, clear, recycle, and reuse. At the same time, urban jobsites are getting tighter, transport costs remain a major concern, and more customers want material to be reused where possible.
The ALLU Concrete Bucket responds to this shift in a very practical way. It helps contractors process material closer to where it is generated. That can reduce hauling, reduce double handling, save space, and support more efficient reuse of demolition material.
This is where sustainability and productivity meet. Processing concrete waste on site is not only about reducing waste. It is also about making the jobsite work better.
A continuation of ALLU’s attachment thinking
For over 40 years, ALLU has focused on helping customers process materials where they are. The Concrete Bucket follows that same principle. Instead of adding more steps to the material handling chain, it gives the excavator more capability and keeps valuable material moving on site.
For demolition contractors, recycling operators, dealers, and rental companies, the benefit is easy to understand: one attachment can help turn difficult pulverized demolition concrete into a more manageable material stream.
And on today’s jobsites, that is exactly the kind of practical innovation contractors need.
