Retrofitting in high-bay warehouses: Targeted upgrades pay off – high-bay racking systems with stacker cranes & pallet conveyor technology

A solidly constructed high-bay warehouse can meet the operator's performance requirements virtually without limitations even after 20 years of intensive use. Provided all components are regularly maintained and serviced, the service life of storage and retrieval machines or pallet conveyor systems can be extended even further through targeted retrofitting. With LogBer's support, costly new investments can be avoided in a comparatively simple way.

💼 Success story: Longevity through retrofitting

“Renewing aging system components and modernizing outdated control and drive technology is still economically viable and worthwhile for a high-bay warehouse, even after more than 30 years of operation,” says Gerhard Keller, Managing Director of LogBer GmbH. “While such an investment is typically depreciated over 15 to 20 years, in practice even high-bay warehouses operating 24/7 with high performance requirements often function well beyond this period.” As an example, Gerhard Keller cites a system built in 1980 that underwent a targeted retrofit 15 years ago based on a concept developed by LogBer and is still operating unchanged after more than four decades.

📊 Logistics planner with relevant experience

For a successful retrofit in a high-bay warehouse, extensive preparatory work and experienced logistics planners who know how to handle the uncertainties of such a project are essential. In this specific case, LogBer oversaw the renewal of the entire control technology for both the stacker cranes and the pallet conveyor system. All drives for the stacker cranes were replaced with energy-efficient, easy-start drives. Unevenly worn guide rails had to be ground down, and one stacker crane damaged by high dynamic forces had to be completely replaced because significant weld cracks had formed in the carriage and mast.

🛠️ Challenges and Solutions

Beforehand, however, several hurdles had to be overcome, reports LogBer Managing Director Gerhard Keller: “The manufacturer and installer of the high-bay racking system no longer existed. Nevertheless, we found three companies in the logistics market specializing in retrofitting third-party systems for an initial inspection and assessment of the potential costs.” Finally, the systems were modernized aisle by aisle while remaining operational: Control systems (PLC, sensors, etc.) were brought up to the latest technological standards, the drive technology was replaced with more energy-efficient and easy-starting systems, travel and guide rails were readjusted, travel rails were ground, wheels were renewed, and finally, the warehouse management and material flow control were adapted to contemporary logistics requirements.

📝 Careful planning and a step-by-step approach

Nevertheless, Gerhard Keller notes: “The preparation, planning, and execution of a retrofit/reengineering project is very complex overall, and the necessary measures are difficult to calculate in advance.” To be able to estimate the effort as precisely as possible, LogBer divides the process into four phases: The analysis of the current situation and the operational requirements is followed by the development of the retrofit concept, then by detailed planning and tendering of the necessary work, and finally by implementation, testing, and commissioning.

💰 Is it worth the effort?

“While the overall effort is quite substantial, it is definitely worth it,” Gerhard Keller summarizes. The retrofit of the facility, originally built in 1980 and carried out with the support of LogBer, ultimately made the construction of a new high-bay warehouse unnecessary – and reduced costs to just 20 percent of the otherwise required new investment.

In today's world, where sustainability and resource conservation are becoming increasingly important, the story of the high-bay warehouse retrofit demonstrates how existing systems can be used reliably and efficiently for many more years through skillful modernization and maintenance. It exemplifies how technological innovation and logistics planning can go hand in hand to increase operational efficiency while simultaneously reducing environmental impact.

Logistical sustainability is playing an increasingly important role in today's business world. Companies are recognizing that they must not only focus on economic efficiency, but also on environmental and social responsibility. An important component in this context is the optimization of high-bay warehouses, as these can have a significant impact on a company's environmental footprint and operating costs.

High-bay warehouses are widespread in many industries and serve to store large quantities of goods in a small space. They are often highly automated and offer many advantages, such as better space utilization and faster product picking. Nevertheless, there are some important aspects that should be considered when optimizing these warehouses to improve their logistical sustainability.

1. 🌍 Energy efficiency and resource use

The energy efficiency of a high-bay warehouse is crucial for its sustainability. It is essential to ensure that the lighting, air conditioning, and warehouse automation systems operate as efficiently as possible. This can be achieved through the use of LED lighting, intelligent control technology, and regular maintenance.

Furthermore, resource utilization should be optimized. This includes minimizing packaging materials and avoiding waste during the storage and transport of goods. An intelligent shelving system can help reduce space requirements and make product storage more efficient.

2. ♻️ Sustainable materials and construction

When planning and constructing a high-bay warehouse, sustainable materials and construction methods should be given preference. This can include the use of recycled building materials, energy-efficient insulation materials, and environmentally friendly roof and facade systems. A well-insulated warehouse can reduce energy consumption for air conditioning and maintain a stable temperature in the storage areas.

3. 🤖 Automation and Robotics

Automation technology and robotics play a crucial role in optimizing high-bay warehouses. Robots can work more efficiently than humans and can help accelerate the storage and transport of products. This can not only reduce operating costs but also energy consumption, as robots require less energy than human workers.

However, it is important to ensure that the robots and automation systems used are energy-efficient and easy to maintain. This can be achieved through the use of intelligent control systems and regular training for operating personnel.

4. 🌐 Sustainable sourcing and supply chain

Logistical sustainability doesn't end at the warehouse; it extends to the entire supply chain. Companies should strive to develop sustainable procurement practices and select suppliers who use environmentally friendly materials and processes. This can help reduce the ecological footprint of the entire supply chain.

Furthermore, supply chain logistics planning should be designed to optimize transport routes and minimize emissions. This can be achieved, for example, by using environmentally friendly means of transport and consolidating deliveries.

5. 📊 Data analysis and optimization

Continuous data analysis is crucial for optimizing a high-bay warehouse. Modern technologies like the Internet of Things (IoT) make it possible to collect and analyze a wide range of data from the warehouse. This can help identify and eliminate bottlenecks and inefficient processes.

By using data, inventory levels can be optimized, product picking improved, and storage capacity maximized. This leads not only to better operational efficiency but also to a reduction in energy consumption and environmental impact.

6. 👩‍🔧 Employee engagement and training

Employees play a crucial role in ensuring the logistical sustainability of a high-bay warehouse. It is important to raise their awareness and train them in sustainable practices. This can help them adopt energy-efficient behaviors and minimize waste.

Furthermore, employees should be involved in the optimization process. They can provide valuable insights and ideas for improving warehouse processes and reducing environmental impact.

🏢📦 Optimization of high-bay warehouses

Optimizing high-bay warehouses for logistical sustainability is a complex task encompassing various aspects of warehousing and the supply chain. Companies that opt ​​for sustainable practices can not only reduce their environmental impact but also lower costs in the long term and strengthen their image as environmentally conscious businesses.

The measures mentioned above, such as improving energy efficiency, using sustainable materials and technologies, automation and robotics, optimizing the supply chain, data analysis, and employee engagement, are crucial for success in this area.
