RISA

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 acquires the patent involving the concept of trenchers with sliding jib. From then on, the range is enriched with more and more powerful machines, while compactness remains its basic principle. It is now composed of powerful machines (130 to 500 hp) able to work during all the works of installation of networks dedicated to the transport of energy, fluids, and communication.

Our factory is located near Montauban in the Tarn-et-Garonne region, close to the A20 and A62 motorways. The 70 people who make up our team are totally at your disposal to study, define and design the equipment best suited to your needs, and to ensure its manufacture and maintenance in the best conditions.

RISA masters the whole industrial process: R & D, design office and methodologies, mechanic-welding Integration of hydraulic and electronic components which allows us to produce machines with a high level of reliability and performance.

RISA markets its equipment in France and Europe, but also in North Africa, Reunion, Guadeloupe, Martinique, Guyana, and New Caledonia.

More than 2000 machines built by RISA are used every day, in France as well as abroad, by very small companies as well as by national and international groups.
