Bouygues Construction

« Before the trailer arrived on our site, it was tiring for me. As soon as it arrived, it was less work. We are very happy with your machine. Really, thanks to K-Ryole. »

Bouygues Construction, Paris, Kross Construction site

It was a request from Bouygues Construction that initiated the development of the Kross Chantier. After having spotted the K-Ryole technology on the bike trailers, allowing to transport 250kg without effort, Bouygues commissioned the design office to adapt it for construction sites.

K-Ryole then developed the Kross Chantier, an intuitive and sturdy wheelbarrow that allows you to push or pull 250kg with the tip of your finger on uneven terrain.


The Kross has been placed on a rehabilitation site and a second Kross will enter a construction site in the winter. Its mission: to allow a gain in efficiency in the transport of rubble, tools, beams and other materials, while avoiding Musculo-Skeletal Disorders.
