ALLU has years of experience in fore running and inventing new methods and equipment for earthmoving sector. This year Finland origin ALLU brings new innovations to the market again. With mass stabilisation, which is still quite a new method, soft soil masses and even contaminated soils can be transformed into solid and usable land. With the new ALLU 3D Positioning System mass stabilisation work can be performed more accurately and easily than ever before. Also ALLU Screener Crusher family is expanding with new models and in addition new screening technology for bucket type screening devices will be launched too. ALLU presents its Screener Crushers and Stabilisation Systems at Bauma at open air area F7 stand number N718/2.

New equipment for Mass Stabilisation

Mass stabilisation is a method for strengthening soft soils. It can also be used for processing contaminated material by encapsulating the soil in situ and thus preventing the contaminant from spreading into the surrounding areas. Currently the most popular use of mass stabilisation technology is in road construction projects and harbours, however more recently many clients globally are exploring the technique for processing difficult to handle sludge’s, as an alternative to more expensive methods currently being used (e.g. mass change).

The mass stabilisation process is carried out by feeding dry powder like binder from a pressure feeder via hose to the mixing head mounted on an excavator. The mixing head is positioned to the right place on the work area with the help of the new ALLU 3D Positioning System. The ALLU 3D Positioning System consists of 4 modules: computer unit with software, touch screen, base station and gps-sensor utilizing gps -signals.

The new ALLU 3D Positioning System guides the base machine operator to feed right amount of binder and to mix adequately each block of the site. It also tells when to change location and start stabilising from another point. Thus it eases the performance of the mixing work, ensures homogenous mixing results and accurate binder feeding as well as reduces the consumption of the binder. As the end result higher quality and better job site economy can be reached. With the new system the location of the ALLU PM/PMX Mixing Head inside the ground is exactly known. The new ALLU 3D Positioning System can be mounted on every ALLU Stabilisation System, new or old.

New fine screening technology and screening buckets for lighter base machines

The ALLU Screener Crusher D -series is divided into two main categories: screening & crushing and fine screening. Now at Bauma ALLU presents new screening concept for bucket type fine screening. With totally new screening design also wet materials can be screened down to a fine fragment size, like 15 or 25 mm minus, with high productivity. With the new design vaulting or bridging between the screening discs can be minimised.

ALLU also widens its product range to cover smaller base machines too by introducing three new fine screening bucket models for excavators under 12 t and wheel loaders max 5 t. The complete ALLU D –series product program includes now models for 5 – 45 t excavators and 2 – 30 t wheeled loaders. ALLU buckets can be installed also on backhoes, skid steers and telescopic loaders.

Customers will benefit from ALLU’s revolutionary approach, reduce the costs and increase the profitability. The new expanded range offers now a complete solution of material processing from fine screening to screening & crushing as well as for soil remediation and stabilisation. The varied solutions offered by ALLU are endless.

ALLU Finland Oy launch heavy series Screener Crushers

ALLU started this spring at Bauma Munich impressively by launching two new Screener Crusher models. These new models, ALLU SCH and SCM are designed for users who want to treat high volumes of material. Both of the models are designed to fit larger excavators and wheel loaders.

ALLU SCH rocks on pipeline job sites

ALLU SCH is especially designed for pipeline contractors. It is a perfect padding tool because it allows the contractor to screen the soil directly back to the pipeline. This saves money when there is no need to carry the old soil away or to import new material to the trench. This also saves time and can save up to 50% of construction time. ALLU SCH has a heavy motor and strengthened frame construction.

ALLU SCM is a Monster

ALLU SCM is designed for very heavy applications such as crushing light concrete and therefore it has got the nickname Monster. It has strengthened frame construction, two heavy motors and double chains. Even though the Monster is designed for extra heavy applications it also suits perfectly for lighter applications such as composting, crushing glass or screening soil.

Third generation models

Both models represent the third generation of screener crusher buckets. It means they feature plenty of technical advantages. One of the new features is that there is no need for oil drain line which lowers installation costs and makes it easier to use on different base machines. The build-in power adjustment valve protects against hydraulic overload. Also the frame design has changed so that the material flow to the drums is optimal and chain boxes are placed inside the frame. This helps to keep the job site clean. In addition to this, the bucket’s volume has increased considerably.
