Extension of the gripper width

For optimum gripping of the stone layers, it is possible to
change the gripper width (of the main clamping)
Reason: because often the outer feather-steel-lamellas (Fig
21.1) overlaps outside of the stone layer during the gripping
process and thus complicate the direct positioning to an
already laid stone layer eventually.
For this purpose, in each case the two outer feather-steel-
lamellas are depending on each situation (at the planum /
facing bedding sand and both on the machine side of the
main clamping) by replacing the appropriate accessories
"feather-steel-lamellas" (Figure 21.2).

at the main clamping (34010100)
D Feather steel lamellas to reduce the gripper length
at the main clamping (34010016)

●
With a stone layer breadth over 1000 mm the adjustable
pushing-off bar (max. 1200 mm) should be extended.
●
Pull out the spring loaded bolt () and rotate it a little
() at the same time. Then engage the spring loaded
bolt.
●
Then move the pushing-off bar () corresponding to
the stone layer breadth.
Pull out the spring loaded bolt () and rotate it a little
() at the same time and lock it in the borehole again.
●
Adjust the length of the pushing-off bar so, that the rail
NOT stands out of the stone layer contour.
The pushing-off bar should stand back approx. 2 cm
from the outer contour of the stone layer.
