2.9.3 Check on the gripping quality of certain layers of paving stones
For the secure function of the automatic cuber/the device the gripping quality of certain layers of paving stones has
to be checked as follows:
Take the number of blocks you want to grip. The blocks
in main gripper direction have to face the ground.
If the tower is falling, the
blocks can fall out of the
cube moving grab STAZ.
Blocks have "feet" (for instance by torn paver moulds)
Blocks have "bellies" (for instance by wet mixture)
The sand in the gabs of the lowest layer enforces
"bridges" (just with multi layer production)
Spacers do not reach the top ("blind Spacers")
Conclusion: Layer of blocks falls down and tears
apart
51400035
If the tower is standing, the
gripping quality is OK.
