Dead weight:
•is the own weight (without gripping good) of the device.
Carrying capacity/working
load limit (WLL*):
•specify the maximum possible load of the device (for lifting of gripping goods).
*= WLL →(english:) Working Load Limit

2.9 Safety procedures
2.9.1 General
•The use of the device is only permitted in proximity to the ground.
Do not swing it over people heads.
•The stay under lifted load is forbidden. Danger to Life!
•The manual guiding of the device is only allowed at the handles.
•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 jerky lifting and lowering of the device with and without load. e.g. caused through driving fast with
the lifting equipment/carrier over uneven grounds is forbidden. Because the gripping good could fall
down. Unchecked movements of the device.
•Do not lift any components off-centre (always in centre
of gravity), 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)!
•The operator is not allowed to leave the control unit as
long as the device loaded with load. The load must always
be in the range of vision of the operator.
•Never exceed the carrying capacity/working load limit
(WLL) and the nominal width/gripping range of the
device.
•Fig. A
•Do not pull out stuck or tightened loads with the device.
•Never pull or drag loads sideways. Otherwise parts of the
device could be damaged.
(see Fig. A →)
2.9.2 Carrier / Lifting device
•The used carrier/lifting device (e.g. excavator) have to be in good, safe working condition.
•Only authorized and qualified persons are allowed to operate the carrier/lifting device.

3.1 Authorized use
The device TSZ-UNI is specially designed for gripping, transporting and the following laying of gripping
goods such as, steps, kerb stones, contact angle and L-stones. Via the assembly of the accessoire
“steelfinger grippers WB-SQ” ashlar rocks can also be gripped.
The device is used in conjunction with a corresponding lifting device (e.g. excavator).
•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.
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 load is suitable to be handled.
Any doubts about instructions should be raised with the manufacturer prior to use.
ATTENTION: The use of this device is only permitted in proximity to the ground (→chapter “Safety at
work”).
Only stone elements with parallel and plane surface are allowed to be picked-up and handled.
Because the gripping good could fall down.

General

NOT ALLOWED ACTIVITIES:
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 transports with the device are strictly prohibited:
•The transport of people and animals.
•The gripping and transporting of other loads and materials than
described in this operating instruction.
•Never suspend any goods with ropes, chains or similar at the
device.
•Gripping of gripping goods with packaging foil, because they
could fall down.
•The gripping of gripping goods with treated surfaces (such as
painting/varnish, coating or the like), because they could fall
down. Treated surfaces lead to a reduction in the coefficient of
friction between the grippers and the gripping good.
•The gripping and transporting of non-rectangular and round
gripping goods, because they could fall down (see figure to the
right). ➔
•Transportation of material with “feet”, “bellies” and “blind
spacers”.

4.1 Mechanical connection
Use only original accessories, in case of doubt consult the manufacturer.
Take care that the carrying capacity / working load limit (WLL) of the lifting device/carrier is not exceeded,
through the load of the device, the attaching devices (turning device, fork sleeves etc.) and the additional
load of the gripping goods!
Gripping devices always have to be gimballed, so they can swing freely in any position.
In no case it is allowed to mount gripping devices with lifting devices/carriers in a rigid way!
Break of the suspension may occur within short time. Death, severe injuries and material damage can
result!
4.1.1 Lifting eye / Suspension bolt
•The device is equipped with a lifting eye / suspension bolt and can be mounted on various carrier /
lifting devices.
•Take care that the lifting eye / suspension bolt is safely joined with the lifting tackle (e.g. crane hook,
belt) and cannot slide down.
4.1.2 Load hook and chains
Fit suspension ring in the load hook of the lifting device/carrier.
Ensure that the single chains strands are not twisted or knotted.
Attaching the device to the lifting device/carrier, take care that all local safety regulation is observed.
4.1.3 Rotators (optional)
When using rotators, a free-wheel throttle valve must be installed.
In order to prevent a sudden speedup and stopping the rotational movements, as this may damage the
device within a short time.

4.1.4 Fork sleeves (optional)
To establish a mechanical connection between the fork lift truck and the fork sleeves you have to put the
forks into the fork sleeves and fix it with the locking bolt or with a chain/rope, connected to the eyelet on the
fork sleeves and the lift frame.
It is definitely necessary to establish this connection. Otherwise the device could slide form the forks.

6.2 Picture of the automatic release
The device is equipped with an automatic release, that means the OPENING and CLOSING of the gripping arms results
through the set down and lifting of the device.
Pictures of the positions of the automatic release:
•Device is lifted through the lifting
equipment/carrier
•Gripping arms are opened
•Device is set up on the gripping good
•Gripping arms are opened
•Device is lifted through the lifting
equipment/carrier
•Gripping good is clamped and can be
transported to the destination
•With faulty switching, the
change-over switch must be
pushed back manually (e.g. with a
screwdriver) 1)
•Device is set down with the gripping good (on the
ground)
•Gripping arms are opening
•Device is lifted through the lifting
equipment/carrier
•Gripping arms are opened
(laydown position of the device on
the ground)
1) Otherwise there may be faulty switching and when setting down the load this can cause deformation or
damage of the automatic release!
The jerky lifting and lowering of the device with and without load. e.g. caused through driving fast with the
lifting equipment/carrier over uneven grounds is forbidden
When replacing a defective automatic release, it is
essential to ensure that the slots of the two clamping
pins always point downwards.
The position of the slots must not be above or center,
otherwise there is a risk that the automatic release may
jam when switching!
