Concrete crusher bucket for excavators with a capacity of 70 tonnes per hour — the high-productivity hydraulic attachment for excavators in the 16–25 tonne class that processes reinforced concrete, asphalt, natural stone, demolition waste and concrete sleepers directly on site. With a weight of 2,300 kg and compatibility with standard quick couplers, this excavator concrete crusher bucket mounts on existing excavators, loaders and backhoe loaders without modifications, adding industrial crushing capacity without an additional dedicated machine.
The 70 tonnes/hour capacity places this excavator concrete crusher bucket in the category of equipment for medium and large demolition sites, infrastructure rehabilitation and road works where the daily volume of processed material justifies high productivity. The optionally available 24V magnet automatically extracts the metal rebar from the crushed concrete, recovering the ferrous fractions with commercial value.
Key advantages of the 70 t/h excavator concrete crusher bucket
• 70 t/h capacity — industrial productivity — processing 70 tonnes of concrete per hour allows the rapid completion of high-volume demolition without bringing a separate mobile crusher to the site. Over an 8-hour shift, the theoretically processable volume exceeds 500 tonnes.
• Compatible with 16–25 tonne excavators, loaders and backhoe loaders — versatility of mounting on three types of machine in this tonnage class. If you have several machines on site, the bucket can be transferred quickly between them via the standard quick coupler.
• 24V magnet for rebar extraction (optional) — the 24V permanent magnet automatically separates the steel rebar from the crushed concrete, without manual intervention. The recovered ferrous fractions have commercial value on the scrap metal market, reducing the net cost of the demolition operation.
• Processes concrete sleepers and columns — extended capacity compared with crusher buckets in lower classes. Railway sleepers, prestressed concrete columns and massive precast elements are processed directly, without pre-fragmentation with a rock breaker.
• Multi-compatible quick coupler — the mounting system is compatible with various types of standard quick couplers, enabling fast mounting and removal on the machines available on site.
• Wear-resistant material — built from materials resistant to the abrasive wear specific to reinforced concrete, stone and asphalt, with a long service life in continuous production.
• Economic efficiency through on-site recycling — eliminating the transport of concrete waste significantly reduces the total demolition cost. The aggregate produced stays on site and can be reused as fill or sub-base the same day.
• 60-month warranty — extended coverage for an excavator concrete crusher bucket in industrial production, with spare parts in stock at UZINEX.

70 t/h capacity — when this class is justified
Choosing a 70 t/h excavator concrete crusher bucket over smaller models is justified based on the daily volume of material to be processed and the time pressure specific to the site.
On a site demolishing a G+4 residential block, the volume of reinforced concrete can exceed 2,000–3,000 tonnes. With a capacity of 70 t/h and an 8-hour work schedule, this excavator concrete crusher bucket can process the entire volume in 4–6 days, compared with 10–15 days with a 20–30 t/h bucket. The time difference translates directly into site costs, late penalties and the availability of the machine for other projects.
For contractors carrying out road rehabilitation with a concrete or asphalt layer, the high capacity allows the material to be processed and redistributed in the same working day, keeping affected traffic flow to a minimum and meeting contractual deadlines.
Compatibility with three types of machine
This excavator concrete crusher bucket is designed for mounting on three classes of 16–25 tonne machines, which sets it apart from buckets dedicated exclusively to excavators.
On an excavator, the crusher bucket works in the classic mode — demolition and crushing in the same work cycle, with the ability to work at height and in hard-to-reach areas. The excavator's long arm allows crushing structures on the upper floors without fully dismantling the building before processing.
On a front loader, this excavator concrete crusher bucket becomes equipment for processing already-demolished material — piles of concrete resulting from breaker demolition or from other previous stages are picked up and crushed quickly for redistribution as fill.
On a backhoe loader, versatility is at its maximum: the same machine can dig, demolish and crush within the same work schedule, minimising the number of pieces of equipment needed on medium-sized sites.
The 24V magnet — recovering rebar as a resource
The 24V magnet option available for this excavator concrete crusher bucket turns the steel rebar from a by-product of the crushing process into a recoverable resource with commercial value.
Without the magnet, the rebar remains mixed with the crushed concrete aggregate and must be separated manually or by subsequent sorting — costly and time-consuming operations. With the magnet active, the rebar is automatically extracted during the crushing process, collected separately and resold on the scrap metal market.
Over a volume of 500 tonnes of reinforced concrete processed daily, the amount of recoverable rebar can represent 50–80 kg per tonne, i.e. 25–40 tonnes of scrap metal per day — an additional source of income that reduces the net cost of the demolition operation.
Suitable applications for the 70 t/h excavator concrete crusher bucket
This excavator concrete crusher bucket is the equipment chosen by large demolition contractors and by firms specialised in infrastructure works with significant volumes of inert materials to process.
The demolition of industrial buildings, residential blocks, halls, bridges and viaducts made of reinforced concrete is the main application. Large volumes of material, precast sleepers and columns are processed efficiently with the 70 t/h capacity, without requiring independent mobile crushers that would complicate site logistics.
Urban rehabilitation with the replacement of underground infrastructure — sewage networks, electrical cables, gas pipelines — involves demolishing and removing existing concrete structures over long stretches. This excavator concrete crusher bucket allows the excavated concrete to be processed directly, turning the waste into backfill material for restoring trenches.
Road and rail infrastructure works with worn concrete layers, worn sleepers or precast railway elements benefit directly from this bucket's ability to process concrete sleepers — an application specific to this class of equipment.
Frequently asked questions about the 70 t/h excavator concrete crusher bucket
What type of quick coupler does mounting require?
This excavator concrete crusher bucket is compatible with various types of standard quick couplers for 16–25 tonne excavators. The exact compatibility with the quick coupler of your specific machine is confirmed by UZINEX engineers at the quotation stage — free technical consultancy available .
Is the 70 t/h capacity guaranteed for any material?
The 70 t/h capacity is achieved when processing plain concrete of medium strength with a large output particle size. Dense reinforced concrete, hard stone or fine particle size reduce the effective capacity. UZINEX engineers estimate the realistic capacity for the specific material of your site on request.
Does the 24V magnet work with any type of rebar?
The 24V magnet of this excavator concrete crusher bucket extracts all ferrous fractions — concrete reinforcing bars, tie wire, embedded metal profiles. It does not extract non-ferrous fractions. The 24V voltage is compatible with the standard electrical systems of excavators in the 16–25 tonne class.
Is it eligible for projects with European funding?
Yes. UZINEX is a member of the Enterprise Europe Network and supplies equipment for projects with EU funds, including for infrastructure works, urban rehabilitation and the circular economy. The complete technical documentation is provided on request. Leasing options on the credit and leasing page .
