The transformation of warehouse technology: high -bay warehouse as the driver of modern intralogistics

High-bay warehouses are becoming the heart of the German logistics transformation

The German industrial landscape is currently undergoing an unprecedented transformation in warehouse technology. High-bay warehouses are evolving from specialized niche solutions to indispensable components of modern logistics strategies. This transformation is driven by two key factors: massive investments in new storage capacities and the increasing automation of warehouse processes.

Strong growth and investment: The boom in high-bay warehouses

German companies' willingness to invest in modern high-bay warehouses is reaching new heights. Across all sectors, companies are recognizing the strategic importance of efficient storage systems for their competitiveness. Digitalization and sustainability are the driving forces behind this development, with robot-controlled systems and intelligent software playing a central role.

Industry diversity in high-bay warehouse investments

The range of investing companies is remarkable. In the food and beverage industry, the Martin Bauer Group is a prime example. The company constructed a 31-meter-high, silo-style high-bay warehouse with over 10,000 pallet spaces and five aisles. A special feature of this warehouse is its inerting system for fire protection, which reduces the oxygen content by adding nitrogen.

The surge in investment in the pharmaceutical industry is also considerable. Losan Pharma is building an innovative logistics center in Eschbach with a fully automated high-bay warehouse that will serve both as a raw material warehouse for production and as a shipping warehouse. Commissioning is planned for the end of 2026, with the high-bay warehouse being constructed as a self-supporting silo and connected to the production and packaging areas by automated guided vehicles (AGVs).

Capacity expansion and modernization

The investments primarily target three areas: capacity expansion, efficiency improvements, and future-proofing. BENEO, a manufacturer of functional ingredients, invested €7.7 million in a new high-bay warehouse at its Offstein site with a capacity of more than 8,500 Euro pallets. This investment quadrupled the company's storage capacity while significantly reducing transport distances.

Modernizing existing facilities also plays a key role. GEALAN invested around €14 million in a fully automated high-bay warehouse in Tanna, equipped with 5,020 storage locations and a payload of 1,700 kg per cassette. The system achieves a throughput of up to 70 cassette changes per hour.

Automation and Technology: The Digital Transformation of Warehouse Technology

The automation of high-bay warehouses has evolved from an option to a necessity. With Industry 4.0 and the rapid developments in sensors and intelligent technology, as well as market growth in e-commerce and food delivery, warehouse automation is experiencing significant growth.

Storage and retrieval machines as the heart of automation

Storage and retrieval machines (SRMs) are rail-guided vehicles used to stock high-bay warehouses, handling the storage and retrieval of pallets, containers, and bins. These computer-controlled systems automatically travel to the desired location and store or retrieve goods. The machines can move across the entire height and length of a warehouse, thus significantly increasing the overall productivity of the facility.

The operating principle is based on three directions of movement: the direction of travel is designated as the x-axis, the vertical lifting direction as the y-axis, and the lateral aisle direction as the z-axis. Modern storage and retrieval machines operate fully automatically and receive all information through the integrated warehouse management system.

Pallet shuttle systems for maximum efficiency

Pallet shuttle systems are revolutionizing compact storage. These semi-automated, high-performance compact storage systems use an electrically powered shuttle to transport pallets to and from the racking channels. This technology enables greater storage capacity and increased throughput compared to other compact storage solutions.

The efficiency gain is considerable: Modern pallet shuttles achieve high speeds thanks to frequency-controlled electric drives. A pallet shuttle requires only 0.5 to 0.7 seconds per meter for the storage or retrieval process. Shuttle systems can utilize up to 95 percent of the storage area of ​​a channel storage system.

AutoStore systems: Innovation in small parts storage

AutoStore systems represent the pinnacle of automation in small parts storage. These ultra-compact goods-to-person picking systems utilize a grid structure, saving space for walkways and driveways. AutoStore robots traverse the top of the grid at speeds of up to four meters per second, storing and retrieving bins.

The advantages are considerable: companies can quadruple their storage capacity without needing a new building and increase their output tenfold without hiring new staff. The system enables lower personnel costs through increased employee efficiency and higher picking performance through the goods-to-person principle.

Warehouse Management Systems as a Digital Nervous System

Warehouse Management Systems (WMS) form the digital nervous system of modern high-bay warehouses. These software solutions help companies manage and control daily warehouse operations, from the moment goods are received until they are shipped. WMS systems offer real-time visibility of the entire inventory and integrate with other technologies such as barcode scanning, RFID tagging, and robotics.

The effectiveness of modern WMS systems is evident in concrete results: Pets Corner improved picking efficiency by 38 percent, while Rapid Electronics achieved an on-time-in-full rate of 99.6 percent. Virgin Wines was even able to reduce inventory by 24 percent, resulting in cost savings of £2.6 million.

SAP Extended Warehouse Management, as a specialized solution, offers flexible, automated support for efficient warehouse management. The system enables centralized control of all goods movements and provides tools for monitoring warehouse activities.

Industry-specific applications and success stories

Food and beverage industry

The food industry benefits particularly from modern high-bay warehouses, as they must meet specific requirements for controlled environmental conditions and efficient warehouse management for products with varying shelf lives. Westfalia Europe has been developing, building, and maintaining outstanding automated high-bay warehouses for the food industry since 1971, including fresh produce storage, deep-freeze storage down to -35°C, and ambient temperature storage.

Polish snack manufacturer Lajkonik uses a high-bay warehouse with automated reach trucks to meet growing demand. The system increases storage capacity without requiring additional personnel and combines automation with manual transport.

Pharmaceutical and healthcare industry

The pharmaceutical industry is subject to strict regulatory requirements and needs storage systems that meet the highest quality and safety standards. Kyberg Pharma operates a 16,000-square-meter pharmaceutical logistics center with 3,000 racking locations and 3,800 pallet spaces. All products are stored and shipped according to GDP standards, with strict temperature control between 15 and 25°C for regular goods and 2 to 8°C for sensitive products.

Automotive industry

The automotive industry, with its complex supply chains and just-in-time production processes, particularly benefits from modern high-bay warehouses. Volkswagen operates a body shop in Wolfsburg that temporarily stores around 1,000 car bodies in an area of ​​approximately 40 by 70 meters. The company modernized its stacker crane positioning systems to improve efficiency and accuracy.
