In the late 1940's Roquet started a small workshop producing gasogenes and repairing agricultural machinery.
The first hydraulic product was actually a machine for producing pasta.
In the following years Roquet became the supplier for most of the hitches and hydraulic pumps fitted in Spain by Renault, Lanz (now John Deere), Massey Ferguson, etc. In 1970 the company started developing a wide range of industrial and mobile hydraulic products.
Five years later Spain joined the EEC.
Growth in the following years was continuous - requiring the purchase of the foundry and the building of various new factories to keep up with demand.
