Kosten van een geautomatiseerd palletopslagsysteem?

Stop paying to cool empty air.In the cold chain and F&B industry, the real cost isn’t the steel—it’s the refrigeration bill and the land. A standard forklift warehouse wastes 60% of its volume on aisles. Our high-density AS/RS solutions turn that wasted space into revenue-generating inventory, cutting your energy cost per pallet by up to 35% while eliminating the risks of human operation in -25°C environments. |
The Economics of Verticality in Cold Storage
When Facility Managers and Supply Chain Directors ask about the cost of an Automated Pallet Storage System, they are often comparing it to the construction cost of a traditional flat warehouse. This is a flawed comparison, especially in the frozen food and pharmaceutical sectors.
In a traditional setup, you are limited by the safe lifting height of a forklift (usually 10-12 meters). To store 10,000 pallets, you need a massive footprint. In a cold storage environment, a larger footprint means a massive roof surface area and floor slab—the two primary sources of thermal loss.
The Starack Equation: By utilizing a High Bay Warehouse design reaching up to 40 meters, we condense that same 10,000-pallet inventory into a footprint that is 75% smaller. The initial capital expenditure (CapEx) on the automation equipment is frequently offset within 3-5 years by the savings in land acquisition, concrete work, and the perpetual reduction in refrigeration loads.

Cost Factor 1: The Structure (Rack Clad vs. Free Standing)
A significant portion of the system cost depends on the building strategy. For greenfield projects, we strongly recommend a Rack Clad Building structure.
In this configuration, the racking itself serves as the structural skeleton of the building. The roof and wall cladding are bolted directly to the Q355 high-strength steel uprights. This eliminates the need for a separate structural steel grid (columns and beams) for the building shell.
Financial Impact: This approach typically reduces construction time by 20-30% and lowers the overall civil engineering budget. Furthermore, in many jurisdictions, a Rack Clad structure is classified as “equipment” rather than “real estate” for tax purposes, offering accelerated depreciation benefits that directly improve ROI.

Cost Factor 2: Energy Efficiency and “Green” Engineering
For cold chain logistics, the operating expense (OpEx) is dominated by electricity. An AS/RS System is not just a storage machine; it is an energy management tool.
Our Starack stacker cranes are equipped with Regenerative Braking Units. When a 1,000kg pallet of frozen fish is lowered from a height of 30 meters, gravity does the work. The motor acts as a generator, converting that potential energy back into electricity. This power is fed back into the DC bus to drive the horizontal travel motors or returned to the facility grid.
The Data: This feature alone reduces the energy consumption of the crane by 20-30% compared to standard systems that dissipate this energy as heat (which would then require more cooling to neutralize).
Cost Factor 3: Storage Density and Throughput Needs
The complexity of the machine affects the price. We define the solution based on your SKU profile:
- High SKU / Low Volume: We use Single or Double Deep telescopic forks. This offers high selectivity but lower density.
- Low SKU / High Volume (Batch Production): We deploy the Starack-Shuttle system. Here, the stacker crane carries a satellite shuttle that travels deep into the rack (up to 10 pallets deep).
While the Shuttle system adds complexity to the control logic, it drastically reduces the “Cost per Pallet Position” by eliminating aisles entirely. In a freezer, where every cubic meter of air costs money to cool, minimizing aisles is the most effective way to lower the Total Cost of Ownership (TCO).

Cost Factor 4: Integration with Production (WMS & Conveyors)
The final cost component is the ecosystem. A standalone Stacker Crane is useless without the peripherals. The quote will include:
- Infeed/Outfeed Conveyors: To buffer pallets from production lines or receiving docks.
- Profile Checkers: Essential safety gates that ensure no leaning pallets enter the high bay, preventing jams at 30 meters high.
- WMS/WCS Software: The brain that ensures First-In-First-Out (FIFO) compliance—critical for perishable food items. It integrates with your ERP to prevent expired stock losses.
Investing in a robust WMS interface eliminates the “Inventory Black Hole” phenomenon common in manual flat warehouses, where stock is physically present but administratively lost.
Veelgestelde vragen
1. Does the system function reliably in -25°C environments?
Yes. Our Cold Chain AS/RS uses specific low-temperature steel alloys to prevent brittleness, heated control cabinets for electronics, and special lubricants rated for sub-zero operation. We also utilize distinct cabling insulation that remains flexible in deep freeze conditions.
2. How does the cost compare to a VNA (Very Narrow Aisle) forklift setup?
Initially, AS/RS is higher capital expenditure. However, VNA trucks require heated cabins for drivers, frequent battery changes, and strict floor flatness. When you factor in labor turnover (which is high in cold storage), forklift maintenance, and energy costs, the crossover point for ROI typically occurs between years 3 and 4.
3. Can we install this in an existing warehouse building?
Yes, provided the floor slab can handle the point loads of the racking. However, most existing buildings are height-limited (under 12m). To maximize ROI, we often recommend utilizing the vertical space, which may require roof modifications or a new Rack Clad extension.
4. What happens if a crane breaks down inside the freezer?
Reliability is paramount. We use redundant heavy-duty components. In the rare event of a fault, our cranes are designed with a “Rescue Mode” allowing manual release or towing to the maintenance bay at the end of the aisle, so technicians do not have to perform complex repairs at height in freezing temperatures.
5. How does the system handle different pallet heights?
The system is configured with dynamic height detection. If your production output varies (e.g., variable layer counts on beverage pallets), the WMS and profile gate verify the height upon entry and direct the pallet to the most space-efficient storage slot, optimizing vertical utilization.
