The exciting capabilities of the Allu range of Transformers are being seen at first hand in North America. Here, two companies (one in Wisconsin and the other in Canada) have invested in a D series attachment. The processing power of the Transformer has proven to be particularly effective in dredging a river and reducing tree bark for recycling respectively.
The Allu Transformer series comprises of an excavator / loader / tractor mounted processing attachment which screens, pulverizes, aerates, blends, mixes, separates, crushes, feeds and loads materials. This results in the feed material being effectively transformed into highly valuable products, making any business more efficient, and more profitable.
Catering for applications of all sizes, and capable of processing any material that can be screened and sorted, the Allu Transformer series comprises of the compact DL- and D-Series as well as the truly massive M- and G-Series. All are designed to transform the way in which material handling and processing businesses are able to improve their efficiency and profitability.
The Allu Transformer, whatever its size and configuration, is ideal for recycling, processing concrete, waste, soil, sand, tree derived materials, rocks and minerals, as it also aerates, as well as screening, loads and crushes, all of which can be carried out on site. This truly mobile solution provides the versatility and flexibility to enable work to be accomplished more efficiently even in the most challenging environments. This results in substantial savings in material and transport costs, as no time is lost when waiting for replacement material.
Special dredging operations in Wisconsin
One such application where the versatility, productivity and efficiency of the Transformer has proved itself is in Wisconsin/USA. Here an Allu DH 3-17 Transformer is being used to remove 600 mm of soil from a navigable river. The Transformer is mounted on a John Deere 470 excavator with a long reach configuration, with a position and angle sensor being mounted to the Transformer so that the operation can be observed on a monitor in the cab of the excavator. A dredge pump for the operation is able to receive material up to 75 mm, with the Transformer removing rocks and other debris without unnecessary downtime.

Recycling in Canada
In Nova Scotia/Canada, another DH 3-17 Transformer is currently being used to separate board material from sawdust, and to crush tree bark. The Transformer solution has proved to be an efficient attachment for the job, as it has replaced the stationary processing equipment which required expensive maintenance as it aged. The Transformer requires fewer people at the work site due to higher utilization, resulting directly in fewer pieces of machinery being needed on site.
Transforming operations
At the heart of both the examples above is the Allu Transformer DH with its unique top screen. Here the screening blades spin between the top screen combs with the end material size being defined by the space between the combs. Effectively these screening combs carry most of the material weight to ensure the drums and bearings take on less impact and load. This construction is clog-free and maintains good capacity even with wet materials (especially useful when dealing with dredged material in Wisconsin).
This configuration means that the DH (and the Allu Transformer D-Series as a whole) has proved to be the ideal solution for dealing with excavated soils and rubble, wood waste etc, with processed material not needing to be transported away. Not only does this result in substantial savings in material and transport costs, but no time is lost when waiting for any replacement material that may be required. Additionally binders can be mixed if the job undertaken requires stabilization.
The Transformer D-Series has been designed to be mounted on 12 t loaders, and 8 t tractors and backhoe loaders. This means they are ideally suited to the requirements of companies requiring limited, yet profitable, material separation, crushing, screening and processing.
