Who we are


Since its creation, at the end of the 1980’s, RISA develops and manufactures a complete range of machines and equipments for the construction of aerial networks (lifting cranes, drilling cranes, winches, etc.) and underground networks (chain trencher, wheel trencher, compaction wheel, etc.)

In 2003, in order to complete its offer, RISA purchases the patent involving the concept of the sliding boom slicers. From then on, the range was enriched with more and more efficient machines, keeping compactness as its basic principle. It is now made up of powerful machines (130 to 500 hp) that can be used for all types of work involving the installation of networks dedicated to the transport of energy, fluids, and communications.
