7.3 Crushing
The crusher arms must be applied at right angles to the material to be crushed.
When the two crusher arms are moved together, the tip penetrates the concrete component
and this leads to the fracture of this part.
If the concrete component does not break by the time the crusher arm internal faces are in
contact with the goods to be crushed, you need to open the crusher arms again and apply
them again.
