Operating procedure of laying cycle
General is it the drivers obligation (of the support vehicle) to have at every time the complete
working area of the support frame and the attachment in his field of view.
He must ensure, that in the danger zone are either persons nor objects
●
Lifting up the HVZ-uni by means of the support frame till the clamp is hanging free.
●
Open the main clamp and the side clamp of the HVZ uni.
Take care, that there is nobody in the danger zone, especially swing range of the side clamp arms.
DANGER OF ACCIDENTS!
●
The adjustment E (position of both positioning chain) ensures, that the side is hanging deeper than
the main clamp arms.
●
Close the main clamp (approx. 1 sec.).
By it the hydraulic cylinder of the pushing-off device (ADV) will extended and the jacking bar lifted.
(These function will be do automatically, if using the SPS automatic program on the installation
machine VM 204 ROBOTEC, see operating manual VM 204 ROBOTEC.)
Operation without hydraulic rotator:
Operation with hydraulic rotator:
●
If there is no rotator between the HVZ an the
support vehicle it is possible to position the
installation clamp without an additional
operator by using this slope to align the steel-
lamellas of the laying side clamps to the
paving stone layer.
The aligned clamp will be dropped centrically
onto the paving stone layer. If the clamp is set
down the lamellas of laying side clamps must
touch the side of the paving stones or have
maximum 2 cm distance.
●
If there is an rotator between the HVZ and the
support vehicle use the function of the rotator
to adjust the clamp to the layer.
For the precise adjustment use the slope of
the clamp to align the steel lamellas of the
laying side clamps to the paving stone layer.
The aligned clamp will be dropped centrically
onto the paving stone layer. If the clamp is set
down the lamellas of laying side clamps must
touch the side of the paving stone or have
maximum 2 cm distance.
Operating when no re-formatting of the stone
layer is necessary:
Operating when re-formatting of the stone
layer is necessary:
●
Close the side clamp and the HVZ-uni adjust
itself automatically centric on the laying unit
(which shall be picked up).
If the clamp is placed on the layer off centre it
is possible that height support of the HVZ uni
will lose contact when the clamp is centred.
In this case:
●
Open side clamp a little bit (HVZ uni will set
down on the paving layer again with the height
support)
●
Close the main clamping
●
Open the side clamping
●
Close the main clamp to align the paving rows
for a unimpeded sliding of the paving rows
without touching the edges.
●
Create a distance of 1 cm between the steel-
lamellas of main clamp and the paving layer
opening the main clamp a little bit.
●
Close the side clamps and the HVZ-uni adjust
itself automatically centric on the laying unit
(which shall be picked up) and the positioning
adapter will move the paving stone in the
necessary direction.
If the clamp is placed on the layer off centre it
is possible that height support of the HVZ uni
will lose contact when the clamp is centred.
In this case:
●
Open side clamp a little bit (HVZ uni will set
down on the paving layer again with the height
support)
●
Close the main clamp
●
Open the side clamp
