BIROTO- Floor Grinding, Polishing Machine

BIROTO is the sander in the photos below with two three-phase motors and two abrasive discs. It is used to sand marble, granite (with water) and even wood floors.
It is also equipped with an inverter that allows it to be used in apartments with the simple 220 v to vary the revolutions at will and reverse the rotation.
Obviously, being a machine with two motors and two plates, it develops a large amount of work, already much higher than a three-phase satellite machine with an abrasive consumption at least half compared to it.
The two abrasive-carrying discs are counter-rotating and so the BIROTO turns out to be absolutely neutral and stable, it doesn't pull anywhere, and is therefore very easy to drive. The machine is patented by us, as it has innovative features:
the two abrasive-holder plates can rotate (even with the machine in operation), together with their motors with respect to a central axis placed between them, so that the machine can assume a minimum frontal space, very contained in order to pass through doors (lit while it is working) or be loaded even in small elevators.
quite simply, it is the only machine for grinding and polishing floors that CAN VARY ITS WORKING WIDTH FRONT ON THE MOVE, ON.
The BIROTO normally with the two discs side by side has a working width of 92 cm (and it is easy to understand that with this width, even large rooms are quickly sanded or polished), then without turning off or disassembling the machine, the indicated lever is pushed. in the photos and it takes on a working width of only 46 cm.
In this configuration the machine passes, always in operation, through doors and then puts it back in an instant, after having passed them in the maximum working position; obviously the machine shrinks to the smallest position even when it has to be loaded, because obviously a 92 cm wide machine does not fit into any lift.
The photos highlight these characteristics by specifying that the model represented has not mounted its water tank, the black box that can be seen on the back is the inverter.
BIROTO has a minimum rotation of 90 rpm therefore crystallization is also carried out with it; with the enormous advantage, however, that crystallizing is as if we were conducting two single disc machines together, given its width of 92 cm.
Simply CRYSTALLIZING WE CAN DO DOUBLE WORK COMPARED TO A SINGLE-BRUSH, with greater ease and stability since BIROTO is neutral.
Extremely easy is also the change of abrasives, just lean on the handlebar that the machine lifts from the front.
