SLC: 2019 Toyota's Finding Success with Exoskeletons

Careful testing led to Toyota requiring exoskeleton as PPE for one of its plants.

As is the way of Toyota much study goes into anything new. And while that is usually applied to manufacturing production methods, it’s also applied to using technology as PPE.

“After extensive testing, this year we are now requiring the use of an exoskeleton as PPR at one of our plants in Indiana,” explained Marisol Barrero, Project Manage at Toyota Motor North America, at the Safety Leadership Conference.

Exoskeletons, which are body-worn devices for the purpose of reducing worker fatigue, have been used by Toyota team members at certain locations since 2015.  

Barrero said the idea really took off at an industry meeting where automakers share best practices. “We are all very open about sharing ideas on safety and the use of technology to enhance safety.  Our motto is there are no secrets on safety.”

By 2017 a few plants jumped on board with regard to testing on exoskeletons. In 2108 we started exoskeleton working groups from a few plants and then joined with educational institutions to formally study the impact.  

In Nov. 2018, Kentucky was the first plant to require exoskeletons as PPE. The Indiana plant followed suit and by the end of 2019 across all plants.

In performing overhead work, company surveys showed that those who wore the exoskeletons reported lower Rating of Perceived Discomfort ( RPE).

An electromyography (EMG) study noted a statistically significant reduction of shoulder and back muscle maximum voluntary contraction (MVC), which translates to less muscle fatigue.

Based on these EMG studies s simple too was developed to systemically identify the processes that would benefit from upper body exoskeleton implementation.

So in November of 2018,  a plant in Ontario, Canada became the first plant that required the use of exoskeletons for certain jobs. By the end of this year, it will be rolled out across all plants.

This deliberate process is why the program has been successful says, Barrero. “We  didn’t just roll it out but instead involved our team members and studies the impact on workers.”

Why did the company choose to categorize its use as PPE? “We feel this best fits the paradigm and was an easy alignment with PPE already in place.”

The benefits of this technology for specific jobs at the company have been fewer injuries and lower costs. While the cost of the equipment can range from $3,000 to $70,000 it is much less compared to the toll of a shoulder injury on a team member.

Toyota is currently evaluating other technologies and their safety applications through its smart technology roadmap.

 

“Our success is due to a number of factors including a strong safety culture, and our enthusiastic safety leads at each plant that help spread these technologies through the plant.”
