Device operation
The locked device (FVZ-UNI) is positioned over the gripping good (bolder) and lowered slowly.
In order to get the grab arms of the device (FVZ-UNI) under the gripping good (bolder) in position, unlock
the interlocking mechanism and bring the device (FVZ-UNI) in grab position.
Be sure that all 3 gripping arms do have a contact point under a stone (overhang), before the gripping good
(bolder) is taken off and transported from the floor!
If the gripping arms had found a safe contact point at the gripping good (bolder), lift the device (FVZ-UNI)
and transport it
carefully
to the destination.
As soon as the device (FVZ-UNI) is completely set down, the interlocking mechanism will lock and the device
can be lifted again.
If the grab arms of the device (FVZ-UNI) should be
gotten caught by the weight of the gripping good
(bolder), you can proceed as follows:
Change the chain fixation from the suspension lug
(7) of hanging up for lifting into the opposite
suspension lug (4) of hanging up for release.
Now the device (FVZ-UNI) can be released with the
help of the lifting device/support frame from the
gripping good (bolder).
