3.2 Explanation of basic concepts
Gripping range:
●specify the minimum and maximum product measurements of the gripping good, which can
be gripped with this device.
Gripping good (s):
●is the product, which will be gripped or transported.

arms of the device.
Device:
●is the description for the gripping device.
Product dimensions:
●Are the dimensions of the gripping good (e.g. length, breadth, height
of the product).
Dead weight:
●is the own weight (without gripping good) of the device.
Load capacity:
●specify the maximum possible load of the device (lifting of gripping goods).

Unchecked movements of the device.
●While using the device be sure that there are no
persons in the working area. Danger to Life!
●Do not pull out stuck or tightened loads with the
device.
●Do not lift any components off-centre, because
that could fall down.
●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)!
●Never exceed the carrying capacity and the

4.1 Authorized use
The device (FTZ-UNI-15) is universal usable for gripping and moving customary prefabricated concrete products, with clean
gripping surface; like steps, kerbs (also natural kerbs), as well as “Kassler Bord” (Bus- and Train-profil-stones) and so on.
Connected with lifting equipment e.g. a excavator or a crane.
The device (FTZ-UNI-15) is universal usable because of the great opening width and a high carrying capacity.Look at the
technical data list for details.
This device is series-produced equipped with the
following elements:
universal adjustable opening range
suspension bolt for lifting tackle (crane-hook, belt etc.) at
support frame/lifting device
automatic release for the fully automatic switch over
from „full“ to “empty” .
exchangeable rubber grippers
The opening range of the device (FTZ-UNI-15) can be regulated universal over the spring bolt.
The device (FTZ-UNI-15) is equipped with a automatic release to switching full automatically from “full onto empty” (grip
and to loosen of the gripping goods). That means the opening and closing of the gripper be caused through the set down
and the heave of the device.
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 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”.
●The device is only designed for the use specified in this documentation.
●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.

5.1 Adjustment of the gripping range
Before the product can be lifted and transported, the gripping range has to be adjusted to the dimensions of the
product.
●The adjustment of the gripping range may never take place on both sides at the same time. Always adjust
the gripping range first to the one and then on the other side.
●Pull the spring bolt upwards, rotate around 180° and lock in position (in nick).
●Move the rectangular tube, until the gripping range is approx. 5 cm larger than the product.
●Pull the spring bolt upwards again and rotate around 180°.
●Move the rectangular tube so long until the spring bolt engages in one of the holes.
●The adjustment of the gripping range has to follow general symmetrical.
That means, it must be used in each case the same adjustable hole with both rectangular tubes.
●Caution while adjusting of the gripping range. There is a danger of injuring the hands!

5.2 Adjustment of the threaded rod
The gripping range must be adjusted always in the right way (see adjustment of the gripping range). Otherwise
there is no warranty that the tension force is sufficient for a safety gripping of the gripping good. Otherwise
there is a danger that the load could fall down.
With the adjustment of the gripping range must not the following:
The lower bolt nut on the threaded rod (1) must not drive on block, during the gripping action (lifting of a gripping good).
That means, to keep a minimum distance from 50 mm between the bolt nut (3) and the bottom part (2). Otherwise is the
buffer of the tension force to low.

6.1 Operating for devices with automatic release
●The device is connected to the lifting equipment/carrier (e.g. excavator).
●Before lifting the device, the gripping range has to be adjusted.
●The device is placed over the product, set down, the device closes round the product and it can be lifted.
●Set down on the ground again, the device opens automatically, the automatic release locks it into position so that the
device can be lifted without closing up.
●Placed over the next product, the automatic release disengages itself and the product can be lifted.
●The device therefore is a ONE-MAN-MACHINE.
Shut-down the device without lifting equipment/carrier only on even ground. The gripping arms must be
opened enough, to ensure a secure standing of the device. Otherwise exists danger of overturning!
6.2 Picture of the automatic release
