The third step is the placing of the three basic bodies of the machine, which are able to produce from 1000 to 30000 blocks daily (it equalizes eight working hours ), depending on the cutting of the materials hardness , they are : the mechanic unit for the upright cutting, the mechanic unit for the horizontal cutting and the mechanic unit for the shifting movement .
The last one is moved by an hydraulic engine that is supplied by belts belonging to the central thermal unit and it is necessary for the shifting movement, which takes place on two lines, having two gear : the reduction one is used when the machine is working and it can be possible to change its speed (0/12 meters per minute), by using an adjustment lever strictly connected to the materials features, and a faster gear when the machine is stopped, for faster movements (0/40 meters per minute ).
