The large increase in public works in the field of road construction, which has been taking place during the last few years, faces the contractor with the problem of being able to make use of mobile and semi-mobile plants which can be 

installed and removed without excessive equipments and in the shortest possible time; as well as being simple to maintain and easily accessible, and having the largest output obtainable. Our Firm has tackled this problem on a large scale and is now in a position to supply mobile and semi-mobile plants of all capacities. Experience and the continuous study of constructional techniques, enable us to produce plants in which each group collects a processing system and is connected to others by means of mobile conveyor belts. The units are constructed on a standardised basis so that all the plants can be adapted to the processing of the most varied materials in the different classes of capacity. This means that it is sufficient to replace or add machine-groups in accordance with requirements in order to obtain plants which cover a very wide range of production with any kind of stone. The electrical equipment can also be supplied on a standardised basis allowing the automatic cycle to be varied at will.
