Sacyr has undertaken a pioneering study to assess the impact of exoskeletons in construction environments as part of the Thematic Lab project.
This initiative, led by Sacyr’s Innovation and Health & Safety departments, aims to promote projects that contribute to the prevention of occupational risks. This effort combines technology, health, and workplace safety, analyzing how these devices can reduce physical effort, enhance ergonomics, and reshape the execution of repetitive and demanding tasks.
Through a rigorous protocol of muscular, kinematic, and functional analysis, different exoskeleton models are compared to identify which is most effective for specific activities.
An exoskeleton is an external, flexible structure—based on springs or elastic bands—that functions as a wearable mechanical aid. In engineering, robotic or passive exoskeletons are used to enhance strength and endurance, both for heavy or repetitive work and for the rehabilitation of people with mobility challenges.
The two departments at Sacyr initiated a study to determine how the introduction of an exoskeleton affects the process of replacing railway sleepers.
The study took place in early October on a railway project being developed by Sacyr. Tests were conducted on various tasks, such as handling heavy components, replacing sleepers, and tamping—activities that combine both effort and repetition.
During the trials, workers were equipped with an exoskeleton and body sensors that measured muscle activity and motion dynamics. Their performance was analyzed both with and without the device to compare and monitor the same variables.
Two exoskeleton models providing lumbar support were tested in the experiment. The main difference between them was that one was flexible, while the other was rigid.
After the pilot test, participants evaluated the exoskeletons from multiple perspectives, including usability, impact on performance, and their overall comfort and experience during use.
The field data collected will be used to assess the potential effects on muscular effort during different tasks, with the goal of informing decisions regarding their implementation and impact on workers’ safety and health.
