Fraxinews2025 ODTH

Why did this project make it onto the agenda now?

Rob: “It had actually been on our minds for a while, but the timing was never right. The market is changing fast: customers expect speed, prices are under pressure and at the same time it’s increasingly difficult to find enough staff. At a certain point you realise something has to change.”

“In the past, the business case never worked out because the height restrictions in this building made a classic crane-based automation system impossible. It was only with shuttle technology that everything fell into place: suddenly we could use the available space to its maximum and make the project financially viable.”

What has been the biggest challenge during this project?

Wim: “The hardest part is that everything has to happen live. We couldn’t use several halls for months while construction was ongoing, but storage had to continue. At times we were really at our limit with 34,000 pallets on site. That required serious juggling, limiting inbound flows and rearranging product categories. It created enormous pressure, but also the satisfaction of succeeding while maintaining outstanding service. Our customers barely noticed the transition.”

Why did you choose shuttle technology?

Rob: “Because it allows us to make smarter use of what was already there. We were able to reuse the existing frames in the new installation, which saved a great deal of money and reduced our environmental footprint by more than 680 tonnes of CO2. The system also offers flexibility: lifts can carry shuttles to different levels, so we can shift capacity where it’s needed depending on demand.”

How did Fraxinus become involved?

Rob: “We sat down with Movu, Stow and an external consultant. During those sessions, Fraxinus emerged as the right partner to handle the in- and outbound systems. They integrate all conveyors, lifts and cabling, and also manage the interface with our existing Magic Black Box.”

The Magic Black Box has been part of your site for some time. What role does it play today?

Wim: “We use that system for fast truck loading. Pallets are buffered and arranged in the correct order for dispatch. Initially, we considered replacing it with the shuttle system, but along the way we decided to keep it because it loads far faster than shuttles can. Fraxinus created the connection so that the system now runs seamlessly within the new automation. In the next phase, a retrofit is planned to upgrade the control system and make the Magic Black Box fully future-proof again.”

How has the collaboration with Fraxinus worked out in practice?

Wim: “Very smoothly. There have been many versions of the plan, and many last-minute changes, but Fraxinus has always responded flexibly. When an adjustment is needed, there’s no fuss but just a shared focus on finding the best solution. Technically, everything fits together perfectly: mechanics, cabling and software complement each other.”

What’s unique about the cooperation in this project?

Rob: “Normally, in a large-scale automation project, an integrator is appointed to coordinate everything. That’s not the case here. Fraxinus communicates directly with Movu and with us as the client — and it works remarkably well. Fraxinus shows great flexibility; they’ll move heaven and earth to get things ready on time. The collaboration with Codius for software and cabling also runs smoothly. The only drawback is the distance, but with Digi X-ON many issues can be resolved remotely. In an upcoming stage of the project, camera monitoring will also be installed.”

Can you give us an idea of the timeline for this project?

Wim: “We began demolition work in June 2024. Phase 1 is already operational, and the rollout of the next phases is in full swing. In total, the construction and installation period spans about eighteen months. By mid-2026, all five phases should be fully operational.”

How do you see the future once the project is complete?

Rob: “By the end, together with the Magic Black Box, we’ll have 30,000 pallets in automated storage. That gives us the scale and flexibility to continue growing over the next twenty years. That’s exactly what Project Elixir is about: giving our site new life for the decades ahead.”

A fraxtion of the project

“At ODTH in Rumst, an existing warehouse is being transformed in five phases into an automated shuttle system from Movu, built within racking supplied by Stow. In total, the project will add around 31,000 pallet spaces. The biggest challenge: working in a live warehouse without halting operations.

Fraxinus developed all in- and outbound systems. Pallets enter via conveyors, are automatically measured, scanned and subjected to a gabarit check. Compliant pallets proceed to inbound; any deviations are diverted to a manual line.

From the inbound conveyors, pallets travel via vertical lifts to the correct level. The lifts are designed to transport shuttles as well, allowing capacity to be flexibly distributed. The shuttles store pallets in the racks and retrieve them for outbound transport. Conveyors then move the pallets to the expedition zones, where a connection has been created to the existing rapid-loading system. This buffers pallets and arranges them in sequence for efficient truck loading. A retrofit of this system is planned in a later phase.

The warehouse was originally filled with old Stow racking and manual Movu units. These were dismantled block by block; the steel was recovered and reused in the new installation, saving over 680 tonnes of CO2. A central cube structure was retained in the middle of the site, introducing additional height variations and complexity in construction. Fire safety requirements added to the challenge: all zones are enclosed and fitted with liquid containment curbs, even beneath conveyors. This demanded precise integration and close coordination throughout every phase.

In addition to the mechanical systems, Fraxinus supplied the complete cabling and control system installation, including safety features such as fencing, signalling and access detection. The system processes 2,500 to 3,000 inbound and outbound pallets per day, and provides a total of 10,000 extra pallet positions.”
