| High precision workmanship and the the use of high quality materials, allow to obtain elevated powers in a wide range of speeds and small dimensions.
The variation of revolutions to the output shaft is gradual and continous by the means of a drive handwheel located in front: the adjustment is smooth whether in function or at a stop, whether in on or full load.
A revolutions indicator located on the upper side of the speed variator gives the possibility to check the work speed (on request , a wheel complete with gravitational clock can be mounted in place of the normal wheel).
All motion components are made in tempered steel, dimensioned and ground in order to guarantee the total power transmission even at low rotations.
