Screed eccentric adjustment
To pave thicker layers of material, if the
piston rods in the levelling cylinder are
operating close to their limit position and
if the desired paving thickness cannot be
reached, it is possible to alter the ap-
proach angle of the screed by adjusting
the eccentric.
- Pos. I:
- Pos. II
- Pos. III
- The spindle (1) is not adjusted.
- Unfasten locks (2) for eccentric adjustment.
- Swivel screed to the desired position using the lever (3), and engage the locking
knob again.
If the levelling unit is connected to a height controller, this has the function of balanc-
A
ing out any rapid rise in the screed position: The levelling cylinders are extended until
the correct height is reached.
- The change in approach angle can only take place slowly and uniformly on both
sides at once during paving operation, and involves the use of eccentric adjust-
ments. Failing this, any rapid response in the screed could easily cause waves to
appear on the road surface.
The setting process should therefore take place before work starts!
When equipped with rigid screed, the second hole (4) is intended for (item I).
