● Never exceed the maximum capacity of the hydraulic excavator and other carrier.
3.9.2 Safety at installation work
● The manual guiding of is only allowed for devices with handles!
● The load must always be in the range of vision of the operator, during the transporting and laying
operation.
● Do not lift any components off-centre, because that could fall down.
● Set the stone layer carefully down.

● While using the device be sure that there are no persons in the working area. Life danger!!
● The use of the device is only permitted in proximity to the ground. Do not swing it over people heads!
● While using the device the stay of persons in the working area is forbidden. Except it is indispensable,
caused of the way of using the device, e.g. if the device must be leaded by hand.
● The operator is not allowed to leave the control unit as long as the device loaded with load.
● The device should not be opened if the opening path of the gripping arm is blocked by a resistance (e.g.
other concrete blocks or the like)!
● Do not pull out stuck or tightened loads with the device.
● Do not replace the seal of the pressure relief valve to increase pressure without talking to the
manufacturer!
● Never pull or drag loads sideways. Otherwise parts of the device could be damage
● Never exceed the capacity and the nominal width the device.

3.9.3 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.
If the tower is standing, the
gripping quality is OK.
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

EK may be used in connection with any carrier (mini-excavator, hydraulic excavator, wheel loader, forklift truck ….)
with a minimum dead weight of 1,500 kg (3,300 lbs).
● To operate the hydraulic installation clamp 2 separate hydraulic circuits are required on the carrier (excavator).
● With the device (HVZ-UNI-II-EK) it is possible to handle one layer of pavers. Do not exceed the and the maximum width
of the device HVZ-UNI-II-EK .
● Only pavers in good quality are allowed for laying. Pavers with „feet, bellies and blind spacers” are not allowed“,
because the complete bricklayer could fall out of the device.
The device is equipped with:
● Adjustable main tension, movable on low-maintenance steel-
polyamid sliders.
● Adjustable side gripping direction for accurate positioning of the
laying formation.
● Three operating handles for optimal guiding of the clamp.
● Height adjustable support for a variable gripping depth.
● Oil pressure gauge.
● With pressure control valve to avoid overload.
● With spring-mounted steel-lamellas for gripping.
● universal excavator suspension (UBA) with hydraulic rotating
motor (360°).
Requirements for hydraulic operation (Operating hydraulics of the carrier)
HVZ-UNI-II-EK:
–Volumetric flow (l/min), usable min. 25, optimal 35 –40, max. 80

● Every other use is not authorized and is forbidden!
● All relevant safety regulations, corresponding legal regulations, especially regulations of the declaration of
conformity, and additional local health and safety regulations have to be observed.
Prior to every operation the user must ensure that:
● the equipment is suited to the intended operation, the functioning and the working condition of the
equipment is examined, and the loads are suitable to be handled.
Any doubts about instructions should be raised with the manufacturer prior to use.

General
12 / 42
V2
GB
ATTENTION: The use of this device is only permitted in proximity to the ground.
Only stone elements with parallel and plane surface are allowed to be picked-up and handled.
Because the gripping good could fall down.
NOT ALLOWED AKTIVITIES:
Unauthorized alterations of the device and the use of any self-made additional equipment
could cause danger and are therefore forbidden!!
Never exceed the carrying capacity/working load limit (WLL) and the nominal width/gripping range of the
device.
All unauthorized transportations with the device are not allowed:
● Transportation of people and animals.
● Transportation of other loads and materials than described in this
manual.
● Never suspend any goods with ropes, chains or similar at the device.
● Transportation of non rectangular and round gripping goods, because
they could fall down. (see figure to the right). ➔
● Gripping of gripping goods with packaging foil, because they could fall
down.
● Transportation of material with “feet”, “bellies” and “blind spacers”.

5.2.1 Adjustment of the hydraulic control
● The hydraulic control is adjusted for an operating pressure
(operating pressure of the carrier –e.g. excavator) of
about 200 bar.
● Should the HVZ are mounted to a carrier with a higher
operating pressure (e.g. 200 bar or higher) must first be
checked, if the complete sequence (close and reopen)
works without problems.
● If the case occurs, that the main clamping (HSP) is already
opened, when the side clamping (SSP) is opening, the
bypass valve (1) needs to be open slightly.
5.3 Setting 170 bar and 200 bar
The bypass valve (see ) integrated in the control unit allows the hydraulic control to be adapted to carrier
machines (crane) with various oil flow rates. For loaders with large oil capacities, the bypass valve is opened even
wider (200 bar). On carrier machines with small oil capacities, the bypass valve is closed (170 bar).
Setting the side clamping / main clamping
Approx. 2 turns to the left to "+" = side clamping
and main clamping open simultaneously.
Approx. 2 turns to the right to "-" = first the side
clamping opens and only then does the main
clamping open.

5.4 Adjustment „Bypass valve“ (valve block at HVZ)
The integrated bypass valve in the control block (see ) allows an adjustment of the hydraulic control to the
carriers (excavators) with different oil flow volumes.
Carriers with large oil flows, the bypass valve is further turned up (rotation anti-clockwise).
Carriers with small amounts of oil flow, the bypass valve is further turned off (clockwise rotation).
Thereafter, secure the bypass valve again with the knurled nut.

GB
5.5 Adjustment additional „Bypass-Valve“ (hydraulic rotator/rotating head)
If the bypass function (of the above-described bypass valve) is not sufficient, for carriers with a larger oil flow volumes
(about 60 to 80 l / min) , to ensure a trouble-free sequence of the HVZ, there is the possibility to assemble an additional
bypass valve (see ) at the hydraulic rotating head.
The bypass valve in the control block (see ) allows an adjustment of the hydraulic control to the carriers (excavators)
with different oil flow volumes.
Carriers with large oil flows, the bypass valve is further turned up (rotation anti-clockwise).
Carriers with small amounts of oil flow, the bypass valve is further turned off (clockwise rotation).
WARNING:
If the shifting force of the side grippers is too low, the bypass valve most likely is opened too far! In this case the bypass
valve has to be tighten up slightly (so the volume flow rate of the oil to the installation clamp is reduced).
For support devices with volume flow rate ≤ 40 l/min the bypass valve remain completely closed!
To support appliances with hydraulic oil flow ≤ 40 l/min, the bypass valve is completely closed!
