Allu screening bucket delivers topsoil benefits for Randall Contracting

FINLAY Group, the UK dealers for Allu products, have helped Randall Contracting to convert waste into a useable product at a cemetery in the South East.

The Essex-based contractors were using an Allu DL-Series bucket, with a fine screening drum to convert material from a large area of the land at the site, which had been used as a tipping area for rubbish, into topsoil. Previously, topsoil had been brought in at large volumes for a variety of uses on the site.

By producing 1,000 tonnes of topsoil from the waste area in 30h with a 14 tonne-excavator, Randall Contracting were able to help their client save thousands of pounds.

The DL-Series buckets feature a ‘top screen’ design which greatly reduces wear, power requirements and allows customers to change grid size using changeable cassettes. The aim has been to create a range that can give customers a convenient and effective screening method in which they can use, as and when required, on various projects rather than hiring or transporting expensive mobile machinery.

The fine screening drum minimizes required power and strain on components while delivering high throughputs, coupled with the ability to screen material that would normally clog and ‘blind’ a mesh screen.

Alan Knight, business development manager at Randall Contracting, said: ‘We are delighted with the Allu screening bucket. It has exceeded our expectations with its performance. We hope to be adding to our Allu range very soon as enquiries are coming in thick and fast.’

Chris Bell of Finlay Hire commented: ‘The project required the fine screening of soil that was too wet and sticky for traditional screening methods. Since then, Randall Contracting have used the bucket on various other projects with great success and can offer this as a service to their customers.’

The ALLUD-Series Screener Crusher Bucket attachment works with wheel loaders, excavators, skid steers or back hoes to screen, crush, pulverize, aerate, blend, mix, separate, feed and load materials all in one stage—increasing the profitability and efficiency of pipeline construction operations. It is an effective tool for pipeline padding and backfilling, because it allows material to be screened on site and then backfilled directly into a trench, eliminating the need for a dedicated stationary screening machine. The ALLU power adjustment valve promotes powerful startup and rotation allowing the attachment to efficiently screen and crush wet or dry material from 0.60-inch to 6-inch (15-mm to 150-mm) fragment sizes. Straight side plate construction makes the ALLU D-Series Screener Crusher Buckets easy to fill and able to hold a greater volume of material, while the standard power adjustment valve prevents overloads. Locating the hydraulics on the back of the attachment keeps them well protected from damage, while patented fender plates protect the bearings and seals. Its patented construction keeps nuts and bolts away from the material flow. ALLU D-Series Screener Crusher Bucket attachments are available in over 60 models to fit any excavator, wheel loader, skid steer or backhoe.

To lower overall usage costs, the ALLU Screener Crusher Buckets feature changeable wear hammers for crushing applications. Universal wear hammers are used for most applications and materials. Long wear hammers are recommended for screening and aerating compost and other soft materials to increase capacity. Axe wear hammers are ideal for crushing bark and mixing compost, while oval wear hammers are designed for screening material with high stone content or when reduced crushing effect is needed. 10-mm-thick screening discs extend the life of the attachment when processing many types of material, including topsoil, black top and dirt, excavated and waste soil, contaminated soil, clay, peat, bark, compost, bio waste, demolition waste, construction waste, milled asphalt, glass, coal, oil shale, limestone and other materials.

New system allows Allu DL Series bucket users to change processing drums with minimal fuss

IN response to customer demand, Allu have developed a new ‘cartridge’ drum replacement system for their DL range of screening and aerating buckets, allowing users to change processing drums with minimal fuss.

Patented rear-mounted drums mean that the complete drum and bearing assembly can be removed and replaced, allowing customers to adapt their Allu bucket to suit different conditions and jobs.

The Allu DL Series includes a range of 15mm to 50mm screening and aerating buckets to fit 2–12-tonne excavators, telehandlers and skid-steers. Applications include fine screening, aeration and homogenizing consolidated materials such as soil or clay for backfill.

Chris Bell of Finlay Hire Ltd said: ‘It’s a welcome addition to the range and allows our customers to have one bucket that they can adapt to suit different jobs and conditions. The DL Series is an ideal tool for landscapers or utilities contractors using smaller plant who want to utilize and reclaim usable products on site.’

Finlay Hire Ltd can supply DL Series buckets as a discounted package with both a fine screening and an aeration drum cartridge, along with optional extras such as multiple bracket heads for different machines for maximum versatility.

The complete range of Allu attachments for screening, crushing, shredding and aerating now covers plant from 2-tonne mini-diggers up to 100-tonne faceshovel excavators working as primary crushers in quarries.

‘We’re happy to be in a position where we can now offer Allu products to suit such a wide range of budgets, base machines and applications,’ said Mr Bell. ‘There’s a machine for customers who want high tonnages and are running heavy plant in demanding applications, as well as units for those who just want an easily transportable screening bucket to complement their plant but don’t want to break the bank.’

ALLU 3D Positioning System uses GPS signals to precisely locate the ALLU PMX excavator-mounted power mixing head, guiding the excavator operator to feed the correct amount of binder and to thoroughly mix each block of the job matrix, the company says.

The system is comprised of four modules, including computer unit with software, touch screen, base station and GPS Sensor. The ALLU Pressure Feeder Data Acquisition System tracks the amount of binder applied and the 3D Positioning System tracks exactly where it was applied. The 3D Positioning System tells the operator when to change locations and begin stabilization from another point, optimizing mixing production rates, while ensuring thorough mixing and accurate binder addition rates.
