Our B 107/20-25 is a completely automatic blockmaking machine which can produce hollow concrete products having a height of 20 or 25 cm. The pro-ducts are first moulded on a steel plate and then laid on a concrete runway.
Invented by SACME in 1969, this method, in comparison with traditional blockmaking machines without steel plate, offers many advantages:
increased compaction of the concrete products because the mouldreceives allthe vibration without dissipating it onto the pavement;
25% reduction in the quantity of cement in each mixture;
formation of perfectly sized concrete products, even though thereare uneven areas in the pavement;
elimination of problems related to the sticking and to the wear ofthe concrete runway;
optimum use of the runway space because of the minimum distan-ce between the concrete products.
The B 107/20-25 is provided with an electromechanical program (patent no. 873398)which is composed of a series of cams and limit switches (no solenoid valves or electro-nic elements are used). This system permits a constant working of the machine even withunfavourable conditions, i.e.: voltage rush, humidity, dust, very hot or cold weather, etc.
