Adjustments
The gripping range must be adjusted always in the right way (look adjustment of the gripping
width). Otherwise there is no warranty that the tension force is sufficient to grip the gripping
good safety and there is no danger, that it will be slide down.
At the adjusting of the gripping range must be accounted, that the lower nut on the threaded rod (1) do 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 nut (3) and the bottom part (2). Otherwise, is the buffer of the tension force to low.
