First gripping trial
●
Position the HVZ-uni with completely opened side and main clamp on top of the layer of pavers. The
steel-lamellas on the laying side main gripper, should touch the pavers.
●
Close side clamp slowly until the heads of the positioning adapters are about 1 cm away from touching
the pavers sideways. The position of the C-profile has to be done, so the C-profile is positioned in about
the middle of the paver layer.
●
Tighten the screws to fix the C-profile on the side clamping arm.
●
To do this, the side clamp has to be completely opened to get access to the screw inside the C-profile.
●
Close the side clamping arms again until heads of the positioning adapters are about 1 cm away from
the pavers.
●
Adjust the positioning adapters so that the heads of the adapters are touching about 1 cm of the middle
of the paver in direction to the laying side main gripper (the reason to do it like this: later on, on a
constant laying process, it could happen that the steel lamellas on the laying side main gripper are not
always touching the blocks exactly when the clamp is positioned over the layer to pick it up. For
example, when there is a distance between the steel-lamellas and the pavers of about 1 cm, the heads
of the positioning adapters will hit the pavers in the middle.)
●
Tighten the screws of the positioning adapters in the right position. Make sure that the measurement
between the head of the positioning adapter and the C-profile is exactly half of the length of the paver,
when you want to do half bond.
●
For pavers, which are wider than approx. 16 cm, it is recommended to use 2 positioning adapters per
paver in order to not turn the pavers during the shifting process.
Without shifting into running bond:
With shifting into running bond:
●
Close side arms completely. Due to the setting of
the side clamp, the blocks are not completely
pressed to one another in order to have a joint
width according to the regulations.
●
In order to avoid that the pavers can not be
shifted into the running bond, because the edge
of the one paver is hiding the edge of the next
one, the layer has to be straightened out with the
main clamping direction first.
●
Close main clamp in order to align the rows of
pavers.
●
Open main clamp slightly to have a distance
between the steel-lamellas and the pavers of
about 1 cm.
●
Just close the main clamp for a very short
moment in order to push out the ADV hydraulic
cylinder and pre-stress the springs of the ADV.
●
Close side clamp completely.
●
Each row of the layer is now shifted by the
positioning adapter into the running bond.
