Clancy Docwra Ltd recently installed 45 km of large diameter potable water pipeline for United Utilities in England. The pipeline was installed in all types of terrain and approximately 18 km of pipeline was installed in association with the ALLU bucket.

The Clancy team found that the ALLU bucket negated the need for imported fill in areas where access was difficult. They reported that the ALLU bucket certainly assisted in reducing costs and with the 60 mm knives, their ALLU bucket performed very well indeed.

Contracts Manager Scott Norris said that, “During the time on site, it never failed or required any maintenance. It worked consistently and given the cost of same, as we expected. I would have no hesitation in recommending the use of an ALLU bucket and I’m looking forward to our next opportunity in using same again.”

The Screener Crusher Bucket is a hydraulically operated attachment for earthmoving equipment. It can be mounted on excavators, wheel-, backhoe- or skid steer loaders. By attaching the Screener Crusher Bucket to your already existing base machine, you actually convert your loader into a efficient primary screening, crushing or mixing unit, which results in radically reduced investment costs for specialised machinery on the job sites. The Screener Crusher Bucket is also one of the most mobile machines that the market has to offer.

The Screener Crusher Bucket is driven with chain drive transmission to the drums and the power of the unit depends on the model varying from 30 kW up to 120 kW. The most effective Screener Crusher Buckets have up to four horizontally rotating drums, which are equipped with changeable hammers. There are different types of hammers for different materials. The weight of the material forces the material onto the drums which, while rotating, crushes big softer particles and screens out stones, metals or any other hard pieces. The mechanism is simple and very ridged and requires small service attention.

In screening applications, all screening jobs which do not require 100 per cent less than 20 mm fragment size of the final product is a direct application for the bucket. One of the most important advantages when doing screening with the Screener Crusher Bucket is that it is able to screen with high capacity even when the material is soaking wet.

All mixing and blending of different soils or other materials together can easily be preformed with the bucket. Examples include stabilisation of sticky clay soil or wet peat in a swamp with chalk in order to make the load capacity of the soil higher. Soil remediation and filling of trenches at pipeline construction sites are one of the most rapidly growing tasks for the Screener Crusher Buckets.

One increasing application for the Screener Crusher Bucket is also to use it as a pre screener, crusher and feeder to a stationary screening plant when screening fine fragment sizes. When doing it this way it is possible to take out the big particles before entering the screening plant (reducing wear and tear), crush big dirt lumps before entering (reducing the amount of over size which in normal case would never enter the mobile screen) and pulverise the material when working in wet conditions. In such way it is possible to reach even 40 per cent higher production capacity and continue the season in spring and autumn.
