Exoskeletons: Revolutionizing Warehouse Operations and Enhancing Worker Well-being

The Persistent Challenge of Labor Shortages in Warehousing

The logistics industry has been grappling with labor shortages since 2018, a situation that has only intensified with the onset of COVID-19. The pandemic, subsequent lockdowns, and shifts in consumer behavior have exacerbated these challenges, particularly in the e-commerce sector. Despite high unemployment rates, there remains a low uptake for warehousing roles, making it crucial for businesses to retain quality personnel to maintain daily operations and profit margins.

In industries like logistics and transportation, blue-collar employee turnover rates can soar as high as 70%. This turnover rate makes it incredibly difficult for companies to keep pace with the ever-increasing supply and demand for goods and services. While some companies have turned to offering incentives or increased wages to retain workers, a recent survey revealed that 78% of turnover is unrelated to wages. This statistic underscores the importance of offering good working conditions, flexible shift scheduling, and other benefits to maintain a stable workforce.

The Rise of Exoskeletons: A Game-Changer for Warehouse Operations

In the face of these challenges, innovative solutions are emerging to enhance human capabilities and improve working conditions in warehouses. One such solution that's gaining traction is the use of exoskeletons. At the 2021 A+A Conference held at the Fraunhofer IPA in Dusseldorf, Germany, DB SCHENKER and Ottobock presented exoskeletons as a potential answer to enhance human strength, provide relief to users, and drive productivity gains in specific business processes.

An exoskeleton is an external frame worn to support the body and enhance biological capacities. Powered by electric motors or the wearer's own body energy, these structures give limbs extra movement and strength. The implementation of exoskeletons in warehouse environments represents a significant step towards robotization that enhances human resilience and sustains employment.

DB SCHENKER's Exoskeleton Implementation: A Case Study

DB SCHENKER, a global leader in supply chain management and logistics solutions, has been at the forefront of testing and implementing exoskeleton technology in warehouse operations. Gerald Müller, Vice President of Industrial Engineering at DB SCHENKER, shared insights from their exoskeleton trials conducted in July 2021.

The company focused on non-motorized exoskeletons that work with the body's energy (a concept known as energy harvesting). These trials yielded significant results in terms of worker relief when lifting and carrying goods. The workflows were meticulously recorded and evaluated both with and without the exoskeletons, providing comparative data on their effectiveness.

Key Findings from DB SCHENKER's Exoskeleton Trials

1. Reduced Physical Burden: The perceived overall burden per blue-collar employee was reduced by approximately 23 tons per week when unloading containers.

2. Increased Productivity: Using the exoskeleton increased the handling time by about 19% during container unloading and palletizing tasks.

3. Improved Posture: In addition to the proven relief, the exoskeleton improved posture during load handling, potentially reducing the risk of long-term musculoskeletal issues.

4. Employee Acceptance: The trials showed encouraging acceptance of the exoskeletons among DB SCHENKER employees, indicating a willingness to adopt this new technology.

5. Reduced Fatigue: Productivity increased due to reduced fatigue among employees, thanks to the relief provided by the exoskeleton.

Müller emphasized an important lesson learned from their experience: "There isn't one exoskeleton that is suitable for all applications. Different types are needed depending on the process requirements. Even where the goal of promoting health remains the same." This insight highlights the need for a tailored approach when implementing exoskeleton technology in warehouse operations.

The Multi-faceted Benefits of Exoskeletons in Warehousing

The implementation of exoskeletons in warehouse environments offers a range of benefits that address multiple challenges faced by the industry:

1. Addressing Labor Shortages

By enhancing human capabilities, exoskeletons can help warehouses operate efficiently even with a smaller workforce. This technology allows companies to maximize the productivity of their existing labor force, potentially mitigating the impact of labor shortages.

2. Improving Worker Well-being

Exoskeletons provide crucial support to workers, reducing the physical strain associated with lifting and carrying heavy loads. This can lead to fewer work-related injuries, both immediate and long-term, improving overall worker health and job satisfaction.

3. Enhancing Productivity

As demonstrated in DB SCHENKER's trials, exoskeletons can significantly increase handling time and efficiency in tasks such as container unloading and palletizing. This boost in productivity can help warehouses meet increasing demand, especially in the fast-paced e-commerce sector.

4. Reducing Turnover Rates

By improving working conditions and reducing physical strain, exoskeletons can contribute to higher job satisfaction. When employees feel valued and taken care of, they are more likely to stay with the company longer and work more efficiently.

5. Cost-Effective Alternative to Full Automation

While full automation can be prohibitively expensive for many warehouses, exoskeletons offer a more accessible way to incorporate technology and enhance operations without completely replacing human workers.

The Future of Exoskeletons in Logistics

The potential applications for exoskeletons extend far beyond warehouse operations. This technology shows promise in various areas, including medical applications designed to help people with mobility disorders. As research and development continue, we can expect to see further advancements and refinements in exoskeleton technology in the coming years.

In the context of warehousing and logistics, the future looks bright for exoskeleton adoption. As more companies recognize the benefits of this technology, it may become a standard part of the warehouse workplace. The successful implementation by industry leaders like DB SCHENKER paves the way for wider adoption, potentially transforming the nature of warehouse work and addressing long-standing challenges in the industry.
