Operation
●
Turn the HVZ- UNI-II in such a way by means of the hydraulic rotator that it can be lowered over the stone
layer which can be gripped.
●
Swivel the HVZ- UNI-II in such a way, that the steel lamellas of the laying main clamping touch the stones.
Swivel further in such a way that the HVZ- UNI-II is in approximately centrically aligned to the paving stone
layer which can be gripped toward the side clamping.
●
Lower the HVZ- UNI-II, until the supporting feet of the HVZ- UNI-II affect the stone surfaces. Do not continue
to lower afterwards! The cross beam may not under any circumstances the HVZ- UNI-II essay be affected and
thus pressure from above on the clip be exercised (by the boom of the support frame).
●
Hydraulic control lever on " Position 1" operate, so for a long time on this position hold, until the following
movements ran off:
main clamping closes
main clamping opens slightly
side clamping closes
side clamping closes
side clamping opens
Explanation: Positions of the control lever
Pos.1 : gripping, laying, reset
Pos. 0: zero position
Pos.3: back movement (ex.: a bend of cycle)
During appropriate use and attitude of positioning adapters the stone situation palletized on so-called "cross
joint" is shifted by this course of motion automatically into the "running bond".
When releasing the hydraulic control lever and/or by leading back the control lever into the central position the
gripping trial can be broken off at each time. By a new movement of the control lever on "close" the operating
procedure will be continued at the stopped position. When moving control lever on "Position 1/open" the last
movement will be reset.
●
Lead back the hydraulic control lever after completely locked grab procedure (side clamping opens perfectly
and swivels completely upward) into the central position.
●
HVZ-UNI-II with the gripped layer of stones situation carefully raise and to the shifting place swivel.
●
Before lifting the paving layer with the support vehicle, move the support point 5-10 cm in direction of the
laying side main gripper either using the boom (excavator) or driving the installation machine. Afterwards the
paving layer can be lifted vertically.
●
Transport the paving layer to the laying position swinging the boom (excavator) or driving the installation
machine.
●
Place the paving layer 5 cm in direction to the open laying ground until the rollers touch the already laid paving
stones.
●
Move the paving layer diagonally to the corner of the laying edge and take care of the correct connection to
the already laid paving stones.
●
Set the paving layer down until the support chains sag lightly.
