Hilti unveils its first exoskeleton


The new exoskeleton weighs about 4 pounds, Selz said, and is worn similarly to a backpack. Ideally, the worker won’t realize the device is there after having it on for a while.


The wearable’s design reduces strain put on the shoulders, arms and elbows for jobs that require frequent lifting to shoulder level and higher, Selz said. Hilti anticipates the EXO-O1 will primarily be used for indoor portions of construction work, such as hanging drywall, maintenance, interior finishes or other mechanical work.


The shrinking number of properly trained and skilled workers in the labor force was a focus during the conception of the product, Selz said. Hilti hopes contractors will find value in retaining skilled workers who may be older by reducing the daily strain on their joints during long days, while also finding a new way to appeal to younger, potential workers who may have concerns of overwork.



Exoskeletons first emerged on the market primarily for the manufacturing industry, where prices start at several thousand dollars. Workers completing repetitive tasks can easily strain their joints from overwork. The original vision of bulky, mech suits -- similar to ones seen in science fiction -- quickly transitioned to smaller wearables, like the EXO-O1, without electrical bells and whistles. The smaller suits respond to the movement of the worker automatically using springs and hydraulics.


Exoskeletons are still relatively new to construction, though some have been marketed directly to contractors. Even with mainstream manufacturer Hilti entering the field, it still may be some time before exoskeletons are regularly seen on U.S. jobsites.


“Any time you bring a new technology, there’s always going to be a combo of early adopters and those waiting to see how the market develops,” Selz said.
