Fraco exoskeleton by mawashi: 2021 update

 

Remember, one year ago, when we announced to the world that in 2021, masons & bricklayers could have an exoskeleton built for them? Well, it’s still happening folks! 2020 was a LOT of things, but it didn’t stop Mawashi Science & Technology from working on this innovation for the masonry industry!

The most exciting part is that the suit has been uniquely standardized. What we mean by that is that the Mawashi team found a way to make sure that the suit would have a unique fit for each user. A set of various sized parts has been developed to make sure that the length of the bottom part perfectly fits the mason/bricklayer, and the upper part has been designed with adjustment mechanisms to fit all sizes.

In the next 5 months, the Mawashi team will upgrade the prototype by testing it with bricklayers and making it better every time. Then, at the beginning of the summer, they will start producing, to have the first 50 exoskeletons ready in September 2021. After that, 50 in October, and 50 in November.

Some of you have already pre-ordered yours - you’ve been patient, it’s coming guys! And for those of you who haven’t yet, please contact our official distributor Fraco Products Ltd if you want more information.
