Setting positioning adapters

clamping
●
The HVZ-UNI with its powerful side clamping action, is capable to
shift not dentated layers of pavers which are palletized in cross bond
into the running bond.
●
To do this special positioning adapters (special accessories) are fixed
on the C-profiles of the side clamp. The number of positioning
adapters, which are needed, is identical with the numbers of rows in
main clamping direction (for example 7 adapters, as shown in this
example, of the paver layer or 5 adapters as shown on the example,
mounted on the C-profile)
●
Direction of main gripping
●
The distance between the head of the adapter and the C-profile is
usually half the length of one block, when half bond is required.
●
In the example shown, length of the paver is 20 cm,
divided by 2 = 10 cm.
●
On the paver layer showed here as an example, on the right hand
side adapters to touch row 1, 3, 5 and 7 should be mounted roughly
in the right distance towards one another.
●
On the C-profile on the left-hand side the adapters are mounted to
touch row 2, 4 and 6.
●
Hydraulically open the main clamp, which is already set correctly,
completely, position it over the pack of pavers, clamp hanging freely.
●
Close side clamping completely.
●
Hanging height should be high enough, so the side clamping is not
touching the pavers.
●
Rough setting of both side clamping parts via screw P until the
length of the layer + half length of one paver (in example shown 5 x
20 + 10 = 110 cm, is showing underneath the scale. See illustration)
●
Measure the distance between the two C-profiles, do the fine tuning
via screw P. So the measurement is about 3 – 4 mm larger than the
actual length of the laying cluster.
●
Doing this, you make sure that the single pavers are not compressed
together completely but still have small joints between one another
in the side clamping direction.
●
This is necessary in order to get the joint width of about 2 ½ mm, as
required by the specifications.
●
Open side clamping completely.
