1.2 Mechanical connection
5.1.1 Suspension lug
●The device is equipped with a suspension lug and can be mounted on various support frames/lifting devices.
●Take careful that the suspension lug is safety joined with the crane hook and can not slip down.
●The maximum carrying capacity of the support frame/lifting device is not allowed to cross over by the
dead weight of the device and the maximum load.
5.1.2 Load hook and chains
●Fit suspension ring in the load hook of the lifting equipment.
●Ensure that the single chains are not twisted and may be easily pulled through the jaws
●Attaching the device to the lifting equipment take care that all local safety regulation is observed.
●It is not allowed to exceed the carrying capacity of the lifting equipment with the device and the maximum
load.
6Adjustments
6.1 Adjustment - gripping range
Before the product can be lifted and transported, the gripping range has to be adjusted to the dimensions of
the product.
●Caution while adjusting of the gripping range. There is danger of injuring the hands!
●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 (5) upwards, rotate around 180° and lock in position (in nick).
●Move the rectangular tube (3), until the gripping range is approx. 5 cm larger than the gripping good.
●Pull the spring bolt (5) upwards again and rotate around 180°.
●Move the rectangular tube (3) 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 (3).

●When gripping L-stones, the gripping range must be adjust asymmetrical (because of the center of gravity of
the L-stone, so that when lifting, the L-stone is in horizontal position).
That means, it must NOT be used the same adjustable hole with both rectangular tubes (3) (a asymmetrical
positioning of the adjustable holes up to 2 holes is allowed).

6.1.1 Accessories –height adjustable support
When using the device (TSZ-uni) in batch operation, for gripping of single stone slabs (batched one upon the
other), we advise to use the accessories “height adjustable support” (43100867)! – see Fig. 1
Therefore, the inside height must not always adjusted again for gripping goods with the same dimensions (see
Figure 1). When picking up in batch operation the top stone slab may only be lifted!
●Caution while adjusting of the gripping range. There is danger of injuring the hands!

7.1 Operating for devices with automatic release
●The device is connected to the lifting equipment/support frame (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/support frame only on even ground. The gripping arms must
be opened enough, to ensure a secure standing of the device.
Otherwise exists danger of overturning!
7.2 Picture of the automatic release

7.4 Handling with steelfinger grippers (WB-SQ)
Before each use of the device, check the steelfinger grippers for mobility, abrasion and contamination
Worn (no longer sharp-edged) or bent steelfinger grippers must be replaced! Otherwise it exists slipping danger
of the gripping good!
1.) Position the device (TSZ-uni) direct over the gripping
good (ashlar rock).
2.) Put the device (TSZ-uni) at the gripping good (ashlar
rock). Then lift the device (TSZ-uni) approx. 20 cm
(7.8").
3.) Remove the safety chain from the chain box and
throw it under the lifted gripping good (ashlar rock)
see Figure A
4.) Suspend the security chain on the other side of the
device (at the hook ).see Figure B
Never grip with the hands under the gripping good (ashlar rock) –danger of squeezing the hands!

is secured by the security chain! see Figure C
The safety chain must never be used as a
"lifting tackle" to attach the device (TSZ-uni)
on the support frame (e.g. excavators)!

Before lifting the gripping good (ashlar rock) be sure that the steelfinger grippers do have a good hold/grip and
that the load is distributed evenly, otherwise there is a high risk of accident!
Touch/guide the device (ZSZ-uni) only on the handles and put the feet out of the danger zone.
