Operation
To avoid that the gripping good could fall down, fix the locking
device in the gripping position (see circle in picture below 
Fig.3), when gripping cones with drain.
●
Now lift the device (together with the gripping good) and move it to the requested position.
●
Lower the gripping good at the place of destination, release the locking device and lift off the device (SHS)
without the gripping good.
●
Lightweight shaft element can be piled on top of
the bottom part already on the pallet, thus both
parts are installed together in one run.
