Understanding Exoskeletons
Exoskeletons are electromechanical devices that are worn by individuals to enhance their physical capabilities and reduce the risk of injuries. They work by providing external support to the wearer’s limbs, back, or other body parts, thereby reducing the strain and stress on muscles and joints. Exoskeletons can be broadly classified into two main categories:
- Active Exoskeletons: These exoskeletons are powered by motors or hydraulic systems, providing active assistance to the wearer’s movements. Active exoskeletons are typically used in heavy-duty industrial settings where workers are required to lift and move heavy objects.
- Passive Exoskeletons: Unlike active exoskeletons, passive exoskeletons do not have any powered components. Instead, they rely on mechanical systems such as springs or levers to provide support and reduce fatigue. Passive exoskeletons are generally lighter and more affordable than active exoskeletons, making them suitable for a wider range of applications.
Advantages of Exoskeletons in Improving Workplace Safety
1. Reduced Risk of Musculoskeletal Disorders (MSDs)
MSDs, such as back pain, sprains, and strains, are among the most common workplace injuries, particularly in industries that involve repetitive motions, heavy lifting, or awkward postures. Exoskeletons can significantly reduce the risk of MSDs by:
- Providing Support and Reducing Strain: By supporting the wearer’s limbs and back, exoskeletons reduce the load on muscles and joints, minimizing the risk of overexertion and strain.
- Improving Posture: Many exoskeletons are designed to promote proper posture, which is crucial in preventing back injuries.
- Reducing Fatigue: By reducing the physical effort required to perform tasks, exoskeletons help workers stay alert and focused, reducing the likelihood of errors and accidents caused by fatigue.
According to Exxovantage, musculoskeletal disorders (MSDs) are responsible for almost a quarter of all sick days in New Zealand and Australia.
2. Enhanced Worker Safety
In addition to reducing MSDs, exoskeletons can enhance worker safety in various other ways:
- Increased Strength and Endurance: Exoskeletons augment the wearer’s strength and endurance, allowing them to perform physically demanding tasks for extended periods without exhaustion. This is particularly beneficial in industries such as construction, manufacturing, and logistics, where workers are required to handle heavy materials or work in challenging environments.
- Improved Balance and Stability: Some exoskeletons are equipped with features that enhance the wearer’s balance and stability, reducing the risk of slips, trips, and falls.
- Protection from Hazards: Exoskeletons can also provide a physical barrier between the worker and potential hazards, such as sharp objects or extreme temperatures.
3. Increased Productivity
By reducing fatigue and enhancing worker safety, exoskeletons can contribute to increased productivity in several ways:
- Reduced Downtime: By minimizing the risk of injuries, exoskeletons can help reduce workplace accidents and the associated downtime.
- Improved Efficiency: With the assistance of exoskeletons, workers can perform tasks more efficiently and with greater precision.
- Extended Work Capacity: Exoskeletons enable workers to work for longer periods without experiencing fatigue, increasing their overall work capacity.
Exxovantage claims a 15% increase in production and a 25% reduction in absenteeism when using exoskeletons.
4. Improved Worker Well-being
The use of exoskeletons can also have a positive impact on worker well-being:
- Reduced Physical Stress: By reducing the physical demands of their jobs, exoskeletons can help workers feel less stressed and fatigued.
- Increased Job Satisfaction: When workers feel safer and more comfortable on the job, it can lead to increased job satisfaction and morale.
- Enhanced Quality of Life: By reducing the risk of injuries and improving overall physical well-being, exoskeletons can contribute to an enhanced quality of life for workers.
Exoskeleton Applications in Various Industries
The versatility of exoskeletons has led to their adoption in a wide range of industries, including:
- Construction: Construction workers often have to lift and carry heavy materials, work in awkward postures, and perform repetitive tasks. Exoskeletons can help reduce the risk of injuries and improve productivity in this industry.
- Manufacturing: Manufacturing workers are also exposed to a variety of ergonomic risks, such as repetitive motions and heavy lifting. Exoskeletons can be used to assist with assembly line tasks, material handling, and other physically demanding jobs.
- Logistics: Workers in the logistics industry are responsible for loading, unloading, and moving heavy packages and materials. Exoskeletons can help reduce the strain on their bodies and improve efficiency.
- Healthcare: Nurses, caregivers, and other healthcare professionals often have to lift and move patients, which can lead to back injuries. Exoskeletons can assist with patient handling tasks, reducing the risk of injuries for both patients and healthcare workers.
- Aviation: Exoskeletons can be used to assist with aircraft maintenance and repair, reducing the strain on technicians and improving efficiency.
- Defense: Exoskeletons can enhance the capabilities of soldiers, allowing them to carry heavier loads and operate in challenging environments.
- Retail: Exoskeletons can assist retail workers with tasks like stocking shelves and moving merchandise, reducing strain and potential injuries.
Some Exoskeleton Models worth Considering
- Hilti EXO-S Shoulder Exoskeleton: This is a passive shoulder exoskeleton that helps reduce shoulder and neck fatigue for workers who perform overhead tasks. The website the information comes from is the Hilti USA website.
- Festool ExoActive: This is an active exoskeleton designed to support tradespeople in various overhead tasks. It is powered by an 18V battery and provides up to 5 kg of support to each underarm. It is part of the Festool 18-Volt system. You can find this exoskeleton on the Festool website.
- Exxovantage Carrysuit Exoskeleton: This is a passive upper-body exoskeleton that reduces the load on the hands, arms, shoulders, and back when carrying heavy loads. It is designed to improve strength and stability for the wearer. Exxovantage also sells Back Exoskeletons, Mid Height Exoskeletons, Shoulder Exoskeletons, and Wrist Exoskeletons, but they are not described in detail. This exoskeleton can be found on the Exxovantage website.
Conclusion
As technology continues to advance, we can expect to see even more innovative exoskeleton designs and applications in the future. The use of exoskeletons has the potential to revolutionize workplace safety and improve the lives of workers across a wide range of industries. By providing external support and augmentation to the human body, exoskeletons can reduce the risk of injuries, enhance productivity, and improve overall worker well-being. As businesses strive to create safer and more efficient workplaces, exoskeletons are poised to play an increasingly important role in the future of work.
