CHECK WEAR OF THE ROCK
Most of our rocks are armoured on the outside
and inside by welding to reduce wear.
The way of armouring depends thereby on the
rule of thumb from main fields of application of
the individual rocks.
See example Fig.: 17:
1 = inner armouring
2 = outer armouring
PREVENTIVE MAINTENANCE
Since the wear largely depends on the
operating conditions, we recommend checking
a new rock for the first time after about 5000
m³ conveyed concrete:
- To do so, clean the concrete pump as usual.
- Bring the rock into a final position.
DANGER
Danger of crushing and injury caused by
switching rock valve!
Switch off the drive motor and empty pressure
accumulator to prevent the rock from moving
independently.
- Loosen the pipeline outlet and check the
inner side of the rock with a torch.
- Bring the rock into the other final position and
repeat the inspection.
Further inspection intervals can now be
determined depending on the condition.
The rock must be exchanged when the basic
material "shows through" in individual places.
The inner armouring usually wears faster than
the outer armouring.
The exterior should be checked no later than
when detecting significant wear on the inside.
