ALLU Transformer M 4-25

The ALLU Transformer M 4-25 buckets have been designed for quick and efficient material processing in quarries, mining and industrial operations by delivering a one-step screening, processing and loading solution capable of handling all materials from wet soils to coal and rock.

The Transformer M series attachment solve chute blockages and other material flow problems by crushing the material and separating hard unwanted impurities in the rock mass while loading the dump truck or conveyor system.

Built tough to suit harsh environments in the mining industry, the frame of each Transformer bucket is made from 100% wear resistant Hardox steel and the M-Series utilises genuine CAT ground engagement tools, ensuring that replacement teeth can be sourced anywhere in the world.  All blades, hammers and bars are hardened steel.

The M series suit 50-160 tonne excavators and 30-90 tonne wheel loaders.
