The New Standard in the Wood Industry: Shuttle Bunker Systems

Eliminating Downtime with Hightech


Modular and Flexible

The Story Behind the Future

"Christian, we need to talk," said a familiar voice on the phone at the beginning of 2019.
It was one of my long-standing customers from the wood industry.
"Costs are exploding and we’re losing customers."
What was the problem? It was the chain conveyor of his wet-chip bunker that caused trouble.
There were repeated failures because in the top bunker layer OSB strands were destroyed, rakes bent or broken.
Moreover, due to this problem and to avoid such unwanted interruptions, his bunker system was operated with just 60% to 70% utilization.
So we needed a solution, fast.

I will be happy to answer your questions about our conveying-technology solutions for the wood industry.
I will be happy to answer any questions you may have about our conveyor technology solutions for the wood industry.
"Why not replace the raking system with shuttle belts, which we already use successfully in the sugar industry for filling processes?
Yes, why not?"
Said and done.
The rest of the story: That very same year, the solution was ready for use, allowing our customer to order two 475m³ shuttle bunkers for his plant.

He even ordered two more shuttle bunkers for new projects.

Our customer is happy, and so are his customers.
Not only am I very glad about this –  it’s the growing demand for our groundbreaking solution that makes me happy, too.

The Innovation

Spreading instead of Raking: 2-Way Shuttle Belt

Wet-Chip-Bunker Revolution
In our patented system, we eliminate the conventional raking system entirely. This significantly decreases the risk of breakdowns, wear and tear, while reducing maintenance requirements to a minimum.
Our groundbreaking shuttle-belt system for wet-chip bunkers is operated without components that often cause unexpected failures, and costs resulting thereof.
Moreover, this material-friendly process prevents damage to OSB strands – in contrast to raking systems with a 5% waste production.
Additional benefits include:
100% bunker utilization (in contrast to approx. 60% to 70% with raking systems)
Bent or broken rakes are no longer an issue.
Significant reduction of downtime
Minimization of labor-intensive service and repairs
Significantly higher plant efficiency

One hour of downtime causes damage of up to EUR 20,000.

Downtime causes damage

System comparison with sample calculation for 20 years

Conventional systems:
A weakness of conventional chain conveyor systems in wet-chip bunkers are long downtimes due to the replacement of chains every two years.
In addition, there are around five unplanned breakdowns per year, which interrupt the production process.
These inefficiencies add up to significant costs, which looks very bad on the balance sheet.
Conventional systems:
- chain replacement every 2 years - duration: 3 days with 6 fitters needed
- 6 unplanned breakdowns, * 3 days downtime each
- Replacement of 5 rakes per breakdown
Maintenance and energy costs: EUR 4,170,800*
Loss of sales: EUR 6,075,000*
Total Amount: EUR 10,245,800*
The AMF-Bruns Shuttle-Bunker System:
The strength of the AMF-Bruns Shuttle-Bunker System lies in its reliability and cost efficiency.
Belt changes are only necessary every five years and the risk of breakdowns due to defective rakes is eliminated.
This reduction in maintenance work and unplanned downtime leads to considerable financial savings.
AMF Bruns Shuttle-Bunker System:
- Belt replacement - duration: 8h, every 5 years
- Failures: no failures due to bent or broken rakes
Maintenance and energy costs: EUR 906,240*
Loss of sales: EUR 675,000*
Total Amount: EUR 1,581,240**
Savings: EUR 8,664,560*
* calculated for a 20-year life cycle of your system. We will be happy to provide a detailed calculation on request and adapt it to your environment.

The New Standard in the Wood Industry: Shuttle-Bunker Systems

The efficiency miracle conquers the wood industry.


Service for the Wood Industry

Fast, accurate and exactly to your requirements

Robotics – the Future of Production

In the dynamic world of industrial manufacturing and material handling, efficiency and accuracy in production also play an important role.
Computer-aided manufacturing systems are the invisible heroes that ensure smooth processes - particularly in times of skilled-labor shortage.
Robotics, therefore, provides valuable support in production.
It enables us to achieve better production quality even with complex geometries, while reducing production times.

Virtual Factory Tour and Simulation

At AMF-Bruns, we use the latest simulation technology and 3D scanning to give our customers a first impression prior to the completion of the actual project.
This also allows us to better calculate dimensions.
That’s also important for the integration of new systems into the existing environment.

Research & Development takes System Sensor Technology to the Next Level

To enable our customers to work with state-of-the-art technology, we rely on innovative sensor technology:
• Knowing in advance when the lifetime of wear parts ends
• Detecting of anomalies in the process at an early stage
• Knowing which product and how much of it is being conveyed or stored in your system.
