Variable Drum
Fast drum and blade changes
The ALLU Variable Drum is a new drum structure with a rapid blade change mechanism. Innovation is designed to streamline your operations and boost your productivity. It’s available across our DN-, DS-, and DH-Series. The VD Drum is a game-changer in material processing efficiency.
Versatility Made Simple: The Variable Drum brings flexibility to your workflow. Individual shaft removal allows for quick blade replacements or adjustments to output sizes, all within a matter of hours. This adaptability is crucial for those requiring varied operations from a single Transformer Screening bucket, enabling easy and fast modifications to meet job demands.
Elevate Your Productivity: Achieve superior screening performance with the Variable Drum, designed for up to a 10% increase in efficiency with a single-blade TS setup. You can get higher output with fewer screening combs and less restriction on material flow. Adjusting output sizes is straightforward, allowing for more efficient operation with less effort.
Effortless Maintenance: The Variable Drum’s innovative design simplifies maintenance tasks. Its two-bolt drum attachment system allows easy changes. Changing wear parts or modifying output sizes has never been easier or cleaner, eliminating the need to access the drive compartment and significantly reducing labor time.
The Variable Drum is currently available for these models.
- DN, DS, DH 2-12, 3-12, 3-17
- DS, DH 4-17
BETTER FOR YOU
BETTER FOR THE ENVIRONMENT
YOUR EFFICIENCY
Screen, crush, aerate, mix and load all in a “one-step operation”. Replace additional machines by completing different work tasks in one go.
YOUR GREEN CREDENTIALS
Less material to be transported to the jobsite means a reduction in fuel consumption. Less materials to a landfill and efficient utilization of waste materials supports sustainability
YOUR MACHINES
Your excavator, wheel loader, and skid-steer will transform into a multifunctional tool that will screen, crush, mix, aerate, pulverize and load all in a one-step operation.
YOUR PROFITS
Less material to a landfill means less expenditure. Re-use the material on site, so there is no need to purchase virgin material. Recycle and utilize the left-over materials and generate an income from it.
D-Series features
ALLU Transformer D-Series Screening Buckets are designed for larger material handling jobs, from compost aeration to landscaping and construction waste treatment, not forgetting pipeline backfilling. This is a hydraulic attachment for excavators and loaders, that screens, crushes, aerates, mixes, separates, feeds and loads materials in a one-step operation.
Efficient – process materials fast and efficiently in one step
Mobile – converts your base machine into a mobile processing plant
Greener – smaller carbon footprint and reduced material transportation costs
Plug & play – simple installation to excavators and wheel loaders
Changeable blades – change between different fragment sizes and applications
Self-cleaning design – works well even with wet materials
